When on the market for a pair of sunglasses, there are a few factors that consumers should take into account when deciding which pair would make the best choice.
- Understanding Ultraviolet Protection
Sunglasses that have the ability to block either 100 percent, or 99 percent of ultraviolet rays, are the preferable choice. Since both UVA and UVB rays can cause eye damage, finding a pair that blocks out both types of rays is crucial. Sunglasses which carry the label, ‘UV 400’, have the wearer covered on both the UVA and UVF front, since such protection blocks rays with a wavelength of up to 400 nanometers. Not only will choosing such a pair protect the eye health, but it will also reduce the chance of the more delicate skin around the eye aging prematurely. Here are some tips.
- Choosing Polarized Lens Protection Is Vital
Consumers should only consider glasses which are marked as polarized. These lenses don’t just provide a darker version of the surroundings, but also decrease glare from surfaces such as snow, glass and water. Since polarized glasses give the wearer a clearer view of their environment, they are far a superior choice over normal tinted lenses, especially for driving and participating in a variety of sports.
- A Quick Guide To Lens Tints
Whilst polarized lenses certainly come up tops for giving the wearer the maximum sun glare protection, some consumers prefer to choose tinted lenses. Lenses are treated to a tinting procedure with the purpose of then absorbing passing light. The color of the tint is a matter of personal preference, however certain colors do offer a variety of benefits.
Gray Tinted Lenses: These lenses do not change or distort color, and will give a reduction in brightness.
Brown and Amber Tinted Lenses: These lenses will cause some color distortion, however they do reduce sun glare to a certain extent, for example blue frequency sunlight glare.
Yellow Tinted Lenses: In comparison with brown lenses, lenses with this tint provide increased glare protection from blue light, hence they give the wearer a clear and sharp view of images, however color is distorted on a greater level.
Green Tinted Lenses: This tint gives the wearer ability to differentiate well between objects. In addition they reduce some glare from blue light.
Rose Tinted Lenses: For people who participate in water sports, or other outdoor activities with a blue or green backdrop, this tint choice is well worth considering, since it offers good object contrast within such backgrounds.
- A Look At Polycarbonate Lenses Or Other Alternatives
Whether the sunglasses are polarized or tinted, polycarbonate lenses are an excellent material choice. The lenses are made by compressing plastic tubes, the process providing a shatter resistant product. In the event that the lenses do suffer a breakage, the tubes will roll together, in contrast to glass and other materials where a breakage causes the material to shatter into tiny pieces. Such a feature gives the wearer a higher level of safety.
CR-39 is an alternative material for sunglasses, another plastic type material this choice is especially seen in prescription glasses. A further option is glass, however this choice is not only heavier for the wearer, but also does not offer the same safety level as polycarbonate lenses.
- Last, But Not Least, Fashion
The current fashion statement for sunglasses is large frames. It could be said that the first and original design for sunglasses is returning to the fashion scene. It should be noted however, that since large frames can put extra pressure on the bridge of the nose, the tops of the ears and the temples, some wearers may suffer from headaches.
A pair of lightweight sunglasses doesn’t have the same risks, so any potential consumer should try on a selection of sunglasses first, before making a purchase. Titanium makes an excellent frame choice, being a lightweight, long-lasting and flexible material. People who wear sunglasses every day will especially appreciate the hypoallergenic and non-corrosive elements to this frame choice, providing a sturdy pair of sunglasses that are built to last.
