WHATS UV PROTECTION THEN?
Ultra Violet, or UV for short, is simply one form of energy emitted from the sun. Although it’s not visible to the human eye, UV rays can cause sunburns, cataracts, retinal damage and in some cases, skin cancer.
When choosing your next pair of sunglasses, make sure they have full UV400 protection. This is your guarantee that the lenses block out harmful UVA & UVB rays up to 400 Nanometers, the industry standard.
All of the sunglasses featured at Fashion-world4u feature UV400 protection.

LENS TYPES
Polycarbonate: The most common lens material found in sunglasses today. Offers the highest impact resistance of any lens material, in fact polycarbonate lenses are 10x more impact resistant than conventional plastic or glass lenses.
Polycarbonate, or PC, can be mixed with many tints to produce lens shades. After injection, the material is placed in a centrifugal force mechanism to adjust its optical correctness and curvature base.
Glass: Provides the best optical quality and highest scratch resistance of all lens materials, although its weight should be considered. Also the material of choice for prescription sunglass lenses.
Acrylic: Unlike polycarbonate or glass, acrylic is not naturally UV protective. As a result, UV coatings are applied during the manufacturing process.

LENS TINTS & COATINGS
Smoke, Gray and Gray-Green Tints: The most common type of lens color. Transmits all colors evenly without changing value of color. Light enough not to impair vision, yet dark enough to provide overall protection from glare. Excellent for bright sunny days.
Copper or Brown Lens Tints: Especially good at blocking the blue light commonly found in diffused light such as one might experience on a cloudy day. Amber can improve both contrast and depth perception, and is a good all-around choice if you live in an area with changeable weather patterns.
Yellow or Amber Tints: High intensity tint for maximum sight performance during low light driving. Excellent for night riding, overcast, haze, or fog conditions.
Rose Tints: Help block blue light, thereby improving contrast. Maximum light and glare protection. Offers high contrast and very soothing to the eyes. Improves road visibility. Many people feel that rose tinted lenses are more comfortable for long periods of time than other lenses.
Mirror Lenses: Good at blocking glare without changing color perception. Quality mirror coatings are effective, but beware of very cheap mirrored sunglasses, as they may trick your eyes into allowing harmful radiation into the interior of the eye.
Polarized: When sunlight bounces off a reflective surface such as glass, water or snow, the result is glare. Glare can be much brighter than the light that caused it, and can irritate or even damage the unprotected eye. Polarized lenses block vertically-reflected light by horizontally aligning the crystalline structure of the lens. This makes them ideally suited for use around water, snow, and for driving. Avoid cheap polarized glasses, because poorly matched lenses may result in eye strain. Polarized lenses eliminate glare (which causes eye fatigue, discomfort, and temporary blurring of vision) and allows for the natural perception of color; no compromise of reds, greens, and yellows.
TAC Lens: TAC stands for Tri-Acetate Polarized lenses and contains 3 laminated lenses. TAC lenses are proving very popular as they are extremely strong and offer less impurities, defectives and shrinkage than most polarized lenses.

WHICH SUNGLASSES IS RIGHT FOR YOU?
THE CORRECT FRAME
Faces come in one of five basic shapes: square, round, triangular, oblong, or oval. By following the recommendations below, you will be able to select from one or more frame shapes or styles to compliment your features and help you look your best.
SQUARE FACE
Compliment a square face with frames that are slightly curved. The top of the frames should sit high enough on the face to downplay the jawline.
ROUND FACE
To play down the roundness, select frames with straight or angular lines. Deep color such as black or tortoise also minimizes fullness.
TRIANGULAR FACE
This shape is defined by a broad forehead and narrow mouth and chin. Frames with a thin rim and vertical lines will help balance the bottom part of the face. Frames should not sit too high on the face or they will emphasize the triangular shape. Avoid large frames, heavy nose bridges, bold colors and square shapes.
NARROW FACE
Long narrow faces are similar to square faces in that chin and cheek are of nearly the same width. Facial length, however, is far greater than the width. Frames should cover as much of the center of the face as possible in order to minimize the length.
OBLONG FACE
Oblong Face More frames look good with this face shape than any other, as long as the size of the frames is in proportion to the face.

CONSIDER THE NOSE!
LARGE NOSE
Large oversized frames are recommended for balance. Small frames will accentuate the nose.
LONG NOSE
Frames with high sidebars that draw attention upward toward the temples and away from the nose are a good choice. A double bridge helps a nose appear shorter.
SMALL NOSE
A high bridge in a light color lengthens a short nose or a nose that his small in proportion to the rest of the face.
