How to tell if sunglasses are fake or authentic?

Many websites on the internet sell sunglasses. Many of them claim they are authentic, some don't exactly say authentic but trick you into thinking replicas are authentic. In reality, it takes a smart shopper to determine which sites can be trusted. This guide will help you apply good judgment in determining which sites sell authentic products:

- Return policy: Stay away from web sites that will not take returns.

- Look carefully at the wording. Most official resellers who sell genuine sunglasses would let you know that what they are selling is authentic. So look for guaranteed authenticity.

- Quality: If a website is claiming that their sunglasses are "high quality", then this may be a cause for concern. Designer brand name sunglasses have a brand for a reason -- the brand speaks for the quality, and it's constant throughout. They may be talking about good quality knockoffs.

How to tell if sunglasses are fake or authentic?

- Examine the photos for packaging. Brand new sunglasses are always packed in a box and supplied with cleaning back and warranty card. Don't trust any seller who doesn't provide those items. The one and only case a seller can lack some of these items is when the sunglasses are not brand new and that cant is a good deal anyway.

- Sometimes fake 'designer' items may say 'designer inspired'. Don't fall for that trick; they say that so they don't get in trouble.

- Guarantee: A web site selling authentic sunglasses will always have a guarantee of authenticity. If there isn't one, you should be concerned.

- Beware of fake packaging. Since many fraud sellers are aware of what a buyer is going to look at first, they try to either fake a box supplied or use a box from a different model.

- Look at the code on the interior temple arm of the glasses. Once you have it, look at the designer site and verify the model number is authentic, a current style, appropriate color, etc.

 -Beware of deals too good to be true. 

- Research. Consider researching the work required to get a good deal when you find it. In the age of the Internet, every sunglasses company has its own website. You should take advantage of it.

- Use caution if the auction seller is using official photos taken from the designer. They may be copy and pasting the photo but selling you something that only looks similar. Make sure that the vendor doesn't use official photos. Well, in that case, you should ask to email you a few real photos. When you get the pictures, look carefully for anything unusual.

- Skip any item with words like "-style" in the title. That word is just screaming that it's a fake item.

- Ask the seller if the items are 100% authentic by and if you find the item isn't authentic they will refund your money, shipping, and handling. If they say no, you should beware.

Whenever you buy online it is important to protect yourself. Always buy designer sunglasses from stores that clearly display contact details and a company registration number on their website. Genuine online retailers have to comply with certain rules, one of them is the obligation to have a refund policy that complies with distance selling laws. Make sure you read their delivery and returns, terms and conditions and privacy policies before you purchase.

What is a gradient lense?

Gradient sunglass lense

Definition of gradient lens:
Gradient lenses have refraction that changes throughout the length of the lens. These lenses are darker at the top of the lens and get progressively lighter at the bottom.

Gradient lenses usually go from less powerful to more powerful, flowing along the length of the lens. Lightly tinted versions of gradient lenses are used mainly in fashion sunglasses.

Sunglasses often have gradient protective power. The most powerful protective section is found at the top of the lens. Protection fades toward the bottom of the lens.

 If your activities vary and you need clear vision mixed with your eye protection, the gradient sunglass can be a useful alternative.

Gradient lenses are not just adding a fashion element to the lens, gradient tint is pragmatically working great for driving. Gradient tin is your perfect option for sunglasses, aesthetically and functionally.

Are Reading Glasses (readers) Safe To Use?

Are readers safe to use?

Are reading (readers) glasses safe to use?
Absolutely. Leading ophthalmologists routinely recommend over-the-counter reading glasses for patients with presbyopia who only need simple magnification. Millions of people worldwide use ready-to-wear reading glasses.

Ready-made reading glasses are available in lots of fun styles and colors, too, so you can experiment with fashion, purchasing a somewhat outrageous pair of glasses without risking a lot of money. If you don't like the style, you can always get another inexpensive pair with a more conservative look. Pre-made reading glasses also allow you to stash extra pairs in different rooms of the house, as well as in your car, office, briefcase, purse, boat, and so on.

Drugstore reading glasses (readers) give an approximation of one's prescription for reading glasses. While they are not nearly as accurate as prescription glasses if the same correction is needed for both eyes and you don’t have much astigmatism they can be recommended for occasional use.

You have to pay more than $100 for a pair of reading glasses from an optician, which might easily be lost or broken.

While readers are perfectly safe to use, they cannot provide the benefits of individual prescription glasses. Prescription glasses can be fine-tuned with bifocal or trifocal lenses to meet the exact needs of each eye and give you the best vision from near to distant and in between. Most people do not have exactly the same prescription in both eyes, and almost everyone has at least a small amount of astigmatism correction in their prescriptions.

The most important thing you can do for your eye health is to get regular eye exams. Routine eye examinations every two years for people over the age of 40 are recommended.

What is a polarized sunglass lens?

What is a polarized sunglass lens?

Polarized sunglasses are specialized eyewear designed to reduce glare and increase contrast sensitivity. Glare distorts the true color of objects and makes them harder to distinguish.

Unlike traditional sunglasses, polarized sunglasses selectively block out glare instead of dimming the entire field of vision. Traditional sunglasses may reduce glare, but they may also block out subtle details about the surroundings because of the dye used in tinting the lenses. 

Polarized lenses are transparent pieces of material, usually glass or plastic, that block certain types of light waves. Sunglasses and camera lenses are often polarized to reduce glare from surfaces, such as light reflecting off a lake or the hood of a car. Somewhat like the way Venetian blinds control the amount of sunlight passing through a window, polarization blocks as much as 50% of the light passing through a lens. The person looking through the lens can still see clearly in most cases, but it reduces the brightness and glare of light.

How They Work?

- When light bounces off of a surface, its waves tend to be strongest in a particular direction — usually horizontally, vertically, or diagonally. This is called polarization. Sunlight bouncing off a surface like water, a road, or metal will usually reflect horizontally, striking the viewer's eyes intensely and creating glare. Most polarized lenses in glasses are laminated with tiny vertical stripes that only allow vertically angled light to enter the wearer's eyes. Glare is eliminated because the horizontal light waves cannot bypass the vertical filter.

Lenses can be polarized to different degrees and in different ways. Most inexpensive polarized sunglasses have a thin film applied on one side of the lens. Many higher quality lenses have film laminated between two layers of lens material, preventing it from being scratched or rubbed off. In addition, the denser the film is, the more polarization it provides.

Today, polarized sunglasses are becoming more and more popular with other sports enthusiasts, including skiers, golfers, bikers and joggers, as well as the general public. Although they are more expensive than traditional sunglasses, polarized sunglasses effectively reduce glare from surfaces other than water, such as snow and glass. Drivers can also benefit from polarization, as the special lenses help reduce glare and reflections from the surface of the road.

How to choose sunglasses for kids

Sunglasses for kids

Kids can be pretty rough and careless when they’re at play. Sunglasses can get smashed, crushed, stepped on or cracked. Broken sunglasses have sharp edges that could potentially cause an eye or face injury. Finding sunglasses that offer 100 percent UV protection, while being a safe and smart choice for an active child, is important.

 Most parents don’t think twice about applying sunscreen to their children to protect them from the sun, but are they as careful about protecting their eyes?

During the summer months, children are often outside enjoying the warm weather and sunshine, whether it’s at the beach or in their backyard. It’s not enough to slip on a shirt, slap on a hat and slop on some sunscreen. UV rays can have the same harmful effects on a child’s eyes as on their skin. On average, a child’s exposure to sunlight is three times as much as that of an adult due to the amount of time they spend playing outdoors.

What should you look for when buying sunglasses for kids?

- Let them choose. You're not the one who has to wear the glasses or hear other kids' comments on them. Children are likelier to actually wear them if they select them themselves.
- Eyeball the glasses. Check to see that lenses are not scratched or warped and have no other flaws that distort vision.  Very young children may not know to complain if the glasses are flawed, so it's up to you to check before buying.
- Double Up. Sunglasses block only rays that come directly through the lenses. The skin around the eyes remains vulnerable to rays entering through the sides or from the top or reflected upwards off snow, sand, water, etc. Wearing a wide-brimmed hat is a good backup, blocking out many rays from above and even from the sides, while also shielding the face and neck. Seeking shade during the sun's most intense hours, 10 a.m. to 4 p.m., provides another level of protection.
- Find glasses that block 99-100 percent of both UVA and UVB rays. Buy ones that indicate the percentage of UVR protection they provide.   The more skin covered, the better, so look for large, wraparound styles.
- Use playground-proof lenses. Kids run, trip, fall, and bounce off objects at an alarming speed. Their sunglasses should match this active lifestyle.  Find impact-resistant, scratch-proof lenses that don't pop out of the frames. Avoid glass lenses, unless recommended by a doctor; plastic is safer. Frames should be bendable but unbreakable. Make sure the glasses fit snugly, close to the face.

Should my child wear sunglasses?

Kids should wear sunglasses

It's a habit to slather kids in sunscreen and pop on their hats before they go out in the sun. But do your kids wear sunglasses? Have you ever wondered if they need to?

It's a good idea to wear sunglasses, because exposure to ultraviolet rays may raise his risk for cataracts and other eye problems later in life. But if your child resists, don't push it. A visor or a hat that keeps the sun out of his eyes might be a more workable choice than shades for babies, toddlers, and even some older kids.

Children under age 10 are at high risk for skin and eye damage from UVR. The skin on their eyelids and around their eyes is more delicate and vulnerable than adult skin. And until about age 10, the lens of a child's eye is clear, allowing greater solar penetration and thus greater UVR-induced ocular changes.

We need to teach children early the importance of wearing sunglasses – just as we teach them to brush their teeth and wear a seatbelt so that they develop good habits that last for life!

Fortunately, good sunglasses protect both the skin around the eye and the eye itself.  While children under 6 months old should never be exposed to the sun, once they reach 6 months, they should wear sunglasses outside. If they require prescription glasses, they should also wear prescription sunglasses.

Here are some situations in which it’s important to remember sunglasses for your child:

- Remember to replace sunglasses once the lenses become scratched, and choose polycarbonate lenses, which provide extra impact resistance if your child will wear the glasses while playing sports.

- While playing outside in any season.  The sun shines bright all year round and can be especially harmful during the winter months when the sun reflects off of white snow.

- Anytime your child will be around water, whether it be the pool, beach, or lake. Like snow, the sun reflects off of the surface of the water and can create a harsh glare.

- While your child goes to an amusement park or sporting event. Spending extended hours in an area with little shade requires the protection of sunglasses. 

-Riding in the car. You wouldn’t think about driving around without sunglasses on when the sun was shining brightly and glaring off other cars, so don’t forget to shade your child’s eyes too.  Even if they may be avoiding UV damage while in the car, sun headaches aren’t fun for anyone.

How to select sunglasses - the online guide

Face shapes for sunglasses

There's such a huge selection of sunglasses styles, prices, and features that sometimes it's hard to decide which pair is the best. What should you look for in a pair of sunglasses? Three important qualities: good eye protection, comfort, and fantastic style.

Your new sunglasses must provide protection from ultraviolet radiation a component of sunlight that contributes to eye disease. We recommend you to look for sunglasses with lenses that block 99-100% of UVA and UVB radiation. The label should read either UV 400 or 100% UV protection.

Finding a pair of sunglasses you love is easier if you start thinking about your possible choices now before you go shopping.

When selecting sunglasses, you may wonder how to pick out the best frames for your face shape?

First, determine your face shape. There are seven basic shapes: round, oval, oblong, triangle, inverted triangle, diamond, and square. Once you determine your face shape follow our guide for choosing an appropriate frame shape for it:

-    Oblong face: frames that are as wide or wider than the broadest part of the face
-    Round faces: rectangular or squarish frames, thicker frames
-    Oval faces: most frames will look good, but especially square and wrap-around

-    Diamond-shaped faces: rimless frames, frames with distinctive brow-lines, or oval frames
-    Square faces: softer-edged frames; round, oval, even cat-eyed, also thinner frames
-    Triangle shaped face: colorful frames or cat-eye sunglasses, also frames with straight toplines
-    Inverted triangle-shaped face: rimless frames, light colors, and materials

The frame size of the sunglasses you select should also be in scale to your face. If you have petite features, don't select oversized frames, they will dwarf your face.

Choosing a Lens Color for sunglasses

Lens color for sunglasses

The color of sunglasses lenses doesn't just affect your fashion statement it affects how well you detect contrast and differentiate colors. Some colors enhance contrast, which can be useful, however, this is often at the expense of color distinction which can cause problems (when you're driving, for example, and need to be able to clearly differentiate the colors of a traffic light). Some sunglasses even come with interchangeable lenses so you can change the color easily, depending on what you're doing.

Here are some advises on how to choose the appropriate lens color for your activity:

- Red/orange lenses are good for snow sports but only on overcast days. If you're a hunter, orange lenses are good for clay targets against open backgrounds.
- Violet lenses are good for hunters who need to see clay targets on a green background.
- Copper sunglasses will mute the sky and grass against a golf ball.
- Blue and green sunglasses enhance the contrast with a yellow tennis ball.
- Gray lenses reduce light intensity without affecting contrast or distorting colors.
- Brown lenses partially enhance contrast by blocking some blue light. Good for snow sports. Also generally good for hunting in bright light, against open backgrounds.
- Amber/yellow lenses significantly enhance contrast because they block most or all blue light, and that makes them popular among hunters who benefit from that contrast when looking at targets against the sky. They're bad, however, for any activity that requires color recognition (like driving!). 

Eye protection from the sun with sunglasses

Protect your eyes with sunglasses

To protect your eyes from harmful solar radiation, sunglasses should block 100 percent of UV rays. Just as the sun’s ultraviolet (UV) rays can damage skin, they can also harm the lens and cornea of the eyes.

UV radiation increases your odds of getting cataracts, which cloud the eye’s lens and lead to diminished eyesight. It has also been linked to macular degeneration, a treatable, but an incurable disease of the macula, a part of the retina that is essential for sharp vision.

Long-term exposure to UV radiation can lead to cataracts, skin cancer around the eyelids, and other eye disorders. In the short term, excessive exposure to UV radiation from daily activities, including reflections off of snow, pavement, and other surfaces, can burn the front surface of the eye, similar to a sunburn on the skin.

Frames with a close-fitting wraparound style provide the best protection because they limit how much stray sunlight reaches your eyes from above and beyond the periphery of your sunglass lenses.

Be sure to select sunglasses that block UV rays. Don't be deceived by color or cost. The ability to block UV light is not dependent on the price tag or how dark the sunglass lenses are.

Wear gray-colored lenses because they reduce light intensity without altering the color of objects, providing the most natural color vision. Lens color is really a matter of preference the most important feature to look for in a sunglass lens is how much UV radiation it absorbs.

Do not forget protection for children and teenagers. They typically spend more time in the sun than adults. Children's sunglasses now come in an array of colorful designs, many modeled after adult styles.

Polarized vs none Polarized?

Are polarized sunglasses worth it?

One of the main issues people encounter before purchasing sunglasses nowadays, is the popular question of what is the difference between polarized and non-polarized lenses?

Nearly every pair of sunglasses you buy give your eyes at least some protection from the sun's harsh rays.

The level of protection varies widely, but even the most bargain-basement pair of tinted lenses offer a bit of shade for your eyes. Polarized lenses take what nonpolarized lenses a step further. Polarized lenses are specially designed to protect your eyes from horizontal glare created by the sun. Think of the glare created when the sun hits the hood of your car. With a nonpolarized lens, that glare will bounce right at you. Although it will be dimmed compared to looking at it without any sunglasses, it will still shine in your eyes. Polarized lenses filter out that glare, protecting your eyes and making it easier to see.

The polarized lenses are used to block the intense light that is reflected from flat surfaces. The sunglasses made from polarized lenses are able to block the glare because they are vertically polarized while the light reflected by flat surfaces is horizontally polarized. The non-polarized lenses have a dark shade and reduce the intensity of light.

Polarized lenses have many benefits but they aren't for everyone. Some ski enthusiasts find that they make seeing the ups and downs of the hills harder than nonpolarized lenses. Others just don't do enough driving or outside sports to make springing for polarized lenses worth the extra cost.

Is it important to wear sunglasses?

Is it important to wear sunglasses?

Are sunglasses important? Of course, they are. As the summer months are upon us, many people will buy a new pair of sunglasses. While it may seem like sunglasses are more of a fashion statement than anything, they are actually a great tool to be used to keep your eyes healthy and to preserve your eyesight.

If you are in the sun too long it is not only bad for your skin but bad for your eyes. You have probably been in the street before without your sunglasses on a sunny day and your eyes hurt. This is not good.

One of the best ways to protect your eyes is to wear sunglasses! 

You really should wear them all of the time, as sunglasses are not just for when it’s really bright outside. Even when it’s cloudy or not very sunny, there are still rays that can have damaging effects on your skin and eyes. Shades can protect your eyesight from sunlight eye damage by protecting you from harmful UV rays.  By wearing sunglasses, you can make a fashion statement and protect your eyes from the sun!

Sunglasses have been popular with people for years, both for comfort and as a fashion accessory. However, as studies and research continue to demonstrate a relationship between UV-A/UV-B exposure and ocular disease, the protection of the long-term health of your eyes is yet another reason to wear sunglasses.

When you're choosing sunglasses, look for UV-protection details on product labels. Choose sunglasses that block 99 to 100 percent of both UVA and UVB rays. Skip sunglasses that are labeled "cosmetic" and those that don't offer details on UV protection.

Are designer sunglasses worth it?

Designer sunglasses

I do not think designer sunglasses are worth the price. In fact, I normally buy fairly cheap sunglasses because, given my history with sunglasses, they have a high likelihood of being sat on, dropped from my head or otherwise crushed before the end of summer. At least when this happens I only feel bad about being out $15 instead of $200 (or more).

Consider the following:  

- Designer shades can cost up to $500. Even if you keep a pair for five years, that’s still $100 a year. Think of what you could do with that money!

- Most designer sunglasses are all made by the same manufacturer. Luxottica, an Italian company, is responsible for creating shades by all your favorite designers, including Burberry, Bulgari, Dolce & Gabbana, Chanel, Donna Karan, Polo Ralph Lauren, Ray-Ban, Salvatore Ferragamo, Paul Smith, Vogue, Versace, Persol, Tory Burch, Miu Miu, and Stella McCartney.

- While designer brands do make their products more durable, they’re still scratchable and breakable, just like any other pair of sunglasses.
- The most important reason to wear sunglasses is to protect your eyes from the sun’s harmful UV rays. Inexpensive sunglasses offer 100% protection just like pricier designer sunglasses.

With the upcoming 2016 summer season, everyone is stocking up on all their summer essentials. Swimsuits, sunscreen, floppy hat, and sunglasses are at the top of the list for many. While sunglasses are irrefutably essential, many people see them as luxury items you need to have. Yes, they do help block harmful UV rays and protect the eyes from premature aging and cataract. But spending more than $50 on a pair of good sunglasses maybe a little too much for some.
