Sunglasses though mostly treated as a fashion accessory, it also protects the eyes from the harmful glare of the sunlight consisting UV rays. The most common harm is the cataract caused by the UV rays. This reason must be kept in mind to select the right type of sunglasses for eye protection.

That causes a strain in the eyes slowly damaging the ocular field unknowingly. One experiences hazy vision and dizziness after removing the sunglasses. No doubt, these features are generally associated with the cheap and substandard sunglasses.
2. Not to go by the fashion or trends, the color of the lens has some beneficial aspects too. Each color provides a definite range of protection. Yellow lenses provide the maximum protection from blue light, whereas the copper colored lenses provides the highest resolution of the lens.
3. Another important aspect to check out for is the volume of light transmission or VLT. VLT within the range of 18-27% goes very well with those sunglasses on a bright sunny day. Any range above or below the above mentioned percentage gives poor visibility and the solar radiation defense is not sufficient.
4. Persons who spend a lot of time in outdoor activities, sports sunglasses are of great benefit to them. Lightweight sunglasses are preferred by the sportsperson, so that it keeps them relaxed without the feel of any load on their faces.
