Designer Sunglasses: What You Need To Know. Content Provided by the American Academy of Opthalmology
A number of scientific studies indicate that spending long hours in the sun without eye protection can damage your eyes by
contributing to cataracts, macular degeneration, and growths on the eye, including cancer. Based on these studies, ophthalmologists recommend that you wear 99% and above UV-absorbent sunglasses whenever you're in the sun for long periods of time.
When to wear sunglasses
Sunglasses should be worn anytime you are outdoors, particularly under these circumstances:
during the summer, when the level of ultraviolet radiation (UVA and UVB) is at least three times higher than winter; when at the beach or in the water; when participating in winter sports, especially at high altitudes; when using medications that can cause photosentivity.
What to look for when purchasing sunglasses
Most sunglasses are designed to protect our eyes from the sun's harmful effects. Often the labels on sunglasses promise protection from ultraviolet light and other kinds of natural radiation. It is important to know what kind of light you need to protect your eyes from and what type of light is not necessarily harmful.
*BLOCKS 99% OF ULTRAVIOLET RAYS: You should always buy sunglasses with this feature. Long-term exposure to ultraviolet (UV) radiation in sunlight is linked to eye disease. UVB radiation is considered more dangerous to the eyes and skin than UVA radiation. Both plastic and glass lenses absorb some UV light, but absorption can be improved by adding chemicals to the lens material during manufacturing or by applying special lens coatings. Look for sunglasses that block 99% or 100% of all UV light. Some manufacturers' labels say "absorption up to 400nm." This is the same thing as 100% absorption.
*GROUND AND POLISHED: Some nonprescription glasses are ground and polished to improve the quality of the lenses. Nonprescription lenses that are not ground and polished will not hurt your eyes. You do want to make sure that the lenses you buy are
made properly. To judge the quality of nonprescription sunglasses, look at something with a rectangular pattern, such as floor tile. Hold the glasses at a comfortable distance and cover one eye. Move the glasses slowly from side to side, then up and down. If the lines stay straight, the lenses are fine. If the lines wiggle, especially in the center of the lens, try another pair.
*IMPACT RESISTANT: All sunglasses must meet impact standards set by the Federal Food and Drug Administration (FDA) for safety. No lens is truly unbreakable, but plastic lenses are less likely than glass lenses to shatter when hit by a ball or stone. Most nonprescription sunglass lenses are plastic. Polycarbonate plastic, used in many sports sunglasses, is especially tough, but it scratches easily. If you buy polycarbonate lenses, look for ones with scratch-resistant coatings.
*POLARIZED: Polarized lenses cut reflected glare—sunlight that bounces off smooth surfaces like pavement or water. They can be particularly useful for driving and fishing. Polarization has nothing to do with UV light absorption, but many polarized lenses are now combined with a UV-blocking substance. Check the label to make sure the lenses provide maximum protection.
*LENS DARKNESS: A medium lens is good for day-to-day wear, but if you use the glasses for very bright conditions, choose a darker lens. The color and the degree of darkness do not tell you anything about the lenses' ability to block light.
*PHOTO CHROMIC: A photo chromic glass lens automatically darkens in bright light and becomes lighter in low light. Most of the darkening takes place in about half a minute, while the lightening takes about five minutes. Photo chromic lenses come in a uniform or gradient tint. Although photo chromic lenses may be good UV-absorbent sunglasses (again, the label must state this benefit), it takes time for them to adjust to different light conditions.
*WRAPAROUND STYLE: Wraparound glasses are shaped to keep light from shining around the frames and into your eyes. Studies have shown that enough UV rays enter around ordinary eyeglass frames to reduce the benefits of protective lenses. Large-framed wraparound sunglasses can protect your eyes from all angles.
*GRADIENT LENSES: Gradient lenses are permanently shaded from top to bottom or from top and bottom toward the middle. Single-gradient lenses (dark on top and lighter on the bottom) can cut glare from the sky but allow you to see clearly below. They are useful for driving because they don't dim your view of the dashboard. They're not as good, however, at reducing glare in snowy surroundings or at the beach. Double-gradient lenses (dark on top and bottom and lighter in the middle) may be better for sports where light reflects up off the water or snow, such as sailing or skiing. Double-gradient lenses are not recommended for driving because they make the dashboard appear dim.
*MIRROR-COATED: Mirror finishes are thin layers of various metallic coatings on an ordinary lens. Although they do reduce the amount of visible light entering your eyes, do not assume they will fully protect you against UV radiation. blocks 90% of infrared rays. Infrared wavelengths are invisible and produce heat. Sunlight has low levels of infrared rays, and the eye tolerates infrared well. Some sunglass manufacturers make health claims for their products based on infrared protection, but research has not shown a close connection between eye disease and infrared rays.
Giorgio Calvin Klein, Armani, Marc Jacobs, Gucci, Donna Karan, Guess?, Tommy Hilfiger, Fendi, Kenneth Cole, Hugo Boss, Vera Wang, Valentino. The list goes on and on. Designer names are the mainstay of the clothing business, and nearly every notable designer name that you can associate with fashion has found its way into the sunglass business. Even some of the very high-end names, such as Chanel, Dior, and Prada, have recently gained attention by launching sunglass lines. If you crave a fix for a designer name, then you have come to the right place — the sunglass market. For even if you can't swing the cash for that Chanel suit, Armani dress, Fendi handbag, or Cartier necklace, you will find the price for their sunglasses much more palatable.
If you are looking for designer sunglasses but are unsure which name is right for you, be sure to shop at a variety of stores or one shop with a large selection so that you can try on styles from many different lines. Each designer has a certain image that he or she has created through clothing and accessory designs as well as through advertising and promotions. Most optical shops, department stores and sunglass specialty stores will have materials in the sunglass section that portray the images of the designers' lines they feature. You can also question the sales staff about the qualities of each designer. Certainly the true test is in trying the frames on and finding what's right for you. Some lines are more conservative, some are feminine, some are urban and cutting-edge, and some are simply but beautifully designed.
Typically, however, if you like the clothing styling from a designer you will also like their frames. Most designers maintain a large amount of control over the design, pricing and imaging of their sunglasses. This, even though the lines are produced under a license with an eyewear company that has great experience and knowledge in manufacturing and distributing eyewear. The result is a product that is right for that fashion designer and the designer's loyal customers.
Designer Sunglasses and the Celebrity Influence
Celebrities! What is it about this breed of people that keeps us forever scrutinizing their every waking moments (and sleeping ones to, sometimes!!)? Why the need to keep up to date with what they’re eating or what they are wearing? Why do we care where they go when they leave their homes?
We care because we have an insatiable need. An insatiable need to know what they are eating because tomorrow that’s what the neighbor will be eating, an insatiable need to know what they are wearing because tomorrow that person in work will be wearing the same thing.
We have this insatiable need because the world of celebrities dictates modern trends and we do not want to be left behind when it comes to the new trendy food fad, outfit or those new designer sunglasses they seem to be wearing. And it seems that designer sunglasses are by far the hottest fashion accessory associated with celebrities. The bigger the celebrity, the larger the clamour to own a pair of these ‘wonderful’ objects; and let us not forget - the bigger the celebrity wearing a particular brand of designer sunglasses, the happier that particular sunglass manufacturer is!
Now, it’s obvious that sunglasses play an important part in our everyday lives and routines. Their main function is to protect our eyes from the glare of the sun, in doing so providing vital protection from harmful ultra violet rays which can cause serious damage to our eyes. On a much lower level, sunglasses minimize the effects of squinting which can cause the laughter-line effect seen around the eyes. There’s no doubting that celebrities use sunglasses for these vital functions as well, but more often than not they choose their sunglasses as much for fashionable purposes as well as practical purposes. And don’t the major brands know it! All major fashion designers who are worth their salt produce a range of designer sunglasses but these are normally out of the price range of Joe Soap. There is no denying that these sunglasses are exquisite pieces, elegantly crafted with the….celebrity in mind.
These sunglass manufacturers fall over themselves to offer their wares to the top celebs on a complimentary basis, knowing full well that they will have a free, walking advertising board and the eyes of the world on them. And what people see is what people want and they will go looking for them in the shops.
The bottom line is this, just as we need air to breathe, while there are celebrities there will be a market for designer sunglasses.
