 The Insignia or Company Logo.
For most people it is usually the insignia which they look for on a particular pair of designer sunglasses. Unfortunately, sometimes the insignia or logo is either just glued on a non brand pair, or the logo is changed ever so slightly from the genuine brand.
Apart from examining the logo thoroughly and looking for other clearly identifiable features, the best option is to deal with only optical stores of the highest reputation.

Eye Protection You Expect From Designer Brands.
When it’s all said and done, protection of your eyes is the main function of sunglasses. While it’s great to the designer look, make sure that your eyes are being protected.

UVA and UVB are the most damaging. Damage from the UVB fraction is thought to lead to cataracts of the eye and the formation of pinguecla and pterygium, whole the UVA rays are linked to skin cancer and some other skin conditions.

The lenses in your designer sunglasses should provide a minimum of 99% protection form UV rays. The superior lenses used in quality sunglasses should easily meet this standard.

Photocromatic  Lenses.
Most designer sunglasses will have the option of photo chromatic coating which reacts with sunlight and darkens the lenses as sunlight increases. The lenses are also UV protected for your eyes will be shielded from those harmful rays.

Polarized Lenses.
Lenses with polarizing filters block out the damaging reflective glare of the ”side to side” light waves. Light travels in waves and when it's reflected from any object the waves are distorted to include both the vertical and horizontal light waves. Polarized lenses are a great option to reduce the glare from shiny surfaces like metal, glass or water.
 The indirect sunlight which polarized lenses block is not in itself damaging to the eye, but the glare can impair vision and pose some safety risks.
