Every one good looking with sunglasses but with prada aviator sunglasses it make you look like superstars

Prada Aviator Sunglasses Are HOT!
I love Prada Aviator sunglasses. Not just on me but on women, definitely. My girlfriend looks really good with her Prada Aviator sunglasses on. She actually bought new sunglasses last week but after 2 days she decided she didn't like it. That coz it wasn't Aviator and she didn't ask for my advice first, heh? She gave it to his mother.What's good with Aviator sunglasses is it's versatility. You can wear it with either casual jeans outfit or with a suit.

Sun protection, which includes the use of sunglasses. Sunglasses protect your eyes from ultraviolet (UV) rays, reduce eye strain in bright conditions and protect you from flying debris hazards.

1.Understanding LensesLens Material
Lens Material
* Glass-PROS: Superior optical clarity; superior scratch-resistance. CONS: Heavier than others; expensive; glass will "spider" when impacted (but not chip or shatter).
* NXT polyurethane-PROS: Superior impact-resistance; excellent optical clarity; flexible and lightweight. CONS: Expensive.
* Polycarbonate-PROS: Excellent impact-resistance; very good optical clarity; affordable; lightweight and low bulk. CONS: Less scratch-resistance; slightly less optical-clarity than glass or NXT.
* Acrylic-PROS: Inexpensive alternative to polycarbonate, best suited for casual or occasional-use sunglasses. CONS: Less durable and optically clear than polycarbonate or glass; some image distortion.

-Lens Color (Tint)
All sunglass lenses are tinted to cut down on overall brightness and enhance terrain definition. But your choice of tint colors affect your vision by influencing 1) how much visible light reaches your eyes, 2) how well you see other colors, and 3) how well you see contrasts.
* Brown/gray/green-Brown, gray and green lenses are color-neutral, which means they cut down on overall brightness without distorting colors. These darker shades are intended primarily to cut through the glare and reduce eyestrain in moderate-to-bright conditions.
* Yellow/gold/amber-Yellow, gold and amber lenses provide less overall brightness protection, but excel in moderate-to-low level light conditions. They provide excellent depth perception, which makes them perfect for skiing, snowboarding and other snow sports. They also enhance contrasts in tricky, flat-light conditions.
* Rose/vermilion-Rose- and vermilion-colored glasses really do make the world seem brighter. They provide excellent low-light visibility and enhance contrast (perfect for skiing and snowboarding in cloudy conditions). They also enhance the visibility of objects against blue and green backgrounds, which makes them ideal for driving or exploring in forested areas.
* Mirrored or flash coating-This refers to a reflective film applied to the outside surfaces of some sunglass lenses. They reduce glare by reflecting much of the light that hits the lens surface. Mirrored coatings make objects appear darker than they are, so lighter tints are often used to compensate for this.

Lens Coatings
The more expensive the sunglasses, the more likely it has several layers of coatings. These can include a hydrophobic coating to repel water, an anti-scratch coating to improve durability and an anti-fog coating for humid conditions or high-energy activities.

Lens Constructions
Two methods are commonly used. Lenses made via the injection process offer the best in optical clarity, but are more expensive. The bent-sheet process is used to make both performance and inexpensive glasses. High-end styles use a longer process to offer similar optical clarity as injected models, while lower-cost styles used a simplified process that yields a bit less clarity.
Interchangeable Lenses

Polarized Lenses
Polarization is a great feature if you enjoy water sports or are especially sensitive to glare. When light reflects off of flat surfaces, such as a lake, the light waves align in horizontal patterns, creating intense glare. The filters in polarized lenses block these horizontal light waves, substantially reducing blinding glare and its resulting eyestrain.

2.Understanding UV and VLTUV Protection
UV Protection
* UVB rays are the main concern for eyes. According to the American Academy of Ophthalmology, "Long-term exposure to ultraviolet (UV) radiation in sunlight is linked to eye disease. UVB radiation is considered more dangerous to eyes and skin than UVA radiation."
* UVA rays are the primary ones absorbed by your eyes. While they pose far less concern than UVB, doctors still recommend that they be avoided.
* UVC rays are not a concern, as they are blocked by the atmosphere.

Visible Light Transmission
* All-purpose sunglasses have a VLT of around 15-25%. Aim for glasses in this range if you need a pair for everyday use and basic recreational activities.
* Glacier glasses (special sunglasses designed specifically to protect your eyes from the intense light at high altitudes) have a VLT of around 4-10%. Most glacier glasses also have shields to protect your eyes from light coming in from the sides of your lenses. Because of their low light transmission, glacier glasses should not be used for driving or other everyday activities.
* Photochromic lenses automatically adjust to changing light intensities to protect you in a wider range of conditions. These lenses actually get darker (to block more light) on bright days, and lighter when conditions get darker. A couple of caveats: The photochromic process takes longer to work in cold conditions, and it doesn't work at all when driving a car (UVB rays do not penetrate your windshield, so the process is moot).

3.Frame Considerations
Frame Material
* Metal-PROS: Easy to adjust to your face; less obtrusive to your field of vision. CONS: More expensive and less durable than other types; not for high-impact activities; can get too hot to wear if left in a closed-up car.
* Nylon-Manufacturers use different brand names for their frame nylons, including Grilamid and O Matter(TM). PROS: Inexpensive, lightweight and more durable than metal; some have high impact-resistance for sports. CONS: Not adjustable, unless they have an internal, adjustable wire core.
* Acetate and Zyl-Sometimes called "handmades," these variations of plastic are popular on high-style glasses. PROS: More color varieties are possible. CONS: Less flexible and forgiving; not intended for high-activity sports.

4.Find a Pair That FitsFit Tips
Fit Tips
* Frames should fit snugly on your nose and ears, but not pinch or rub.
* The weight of sunglasses should be evenly distributed between your ears and nose. Frames should be light enough to avoid excess friction on these contact points.
* Your eyelashes should not contact the frame.

Shopping online? Look for product descriptions that include fit guidelines such as "fits smaller faces" or "fits medium to large faces" for guidance. A few brands offer temples that are adjustable or come in several lengths.

Fit Adjustments
If you choose a metal or wire-core frame, you can usually adjust the fit by carefully bending the frame at the bridge and/or the temples. You may also be able to adjust the nosepieces, by pinching them closer together or farther apart, to rest on your nose more comfortably.

Lens Shape
* Wrap-around lenses block more of the light hitting your eyes from the side. They improve aerodynamics, cutting down on wind that can dry out your eyes, and provide extra protection against rain, sand and other debris.
* Different lens shapes complement the most common face shapes-oval, square, triangular and round:
o Oval faces look good in just about any shape of lens.
o Square faces, with their high temples, look good in rounded lenses, which soften contours.
o Triangular (or heart-shaped) faces look good in lenses that flare out toward the cheeks.
o Round faces are complemented by square lenses, which lengthen and slim facial lines.

5.Final Thoughts When Is It Most Important to Wear Sunglasses?
The American Academy of Ophthalmology advocates wearing sunglasses anytime you're outdoors, but particularly when:
* It's summer (when UV radiation is at least 3 times higher than it is during winter).
* You're at the beach or near water.
* You're outside at high elevations.
* You're participating in snow sports.
In addition, if you have an eye disease, have had cataract surgery or are taking photosensitizing drugs, you should wear sunglasses whenever you go outside.
