Good service

It is a very useful product during night riding

It was a very good experience. Although it is of not any relevance here, I lost my gold AUM which fell in one of the trial rooms. I realised the next day, met the store incharge, but I think it was too late.

Does it's work

Does it's work, actually bought it for night car driving. Would be good to have something that is specific to that purpose and which reduces the oncoming headlight glare while keeping the brightness level.

Amazing Product

Worth for money.amazing product.very useful in night.


This product is very useful for ridding in the night . It saves my eyes from flying insects and dust of air ..............!!!!!

Good value

Getting a pair of glasses that fitted my face comfortably and also allowed good protection from wind was essential. These glasses did all that and at a great price. A Win-Win.

Super glasses

Bought another pair as I lost the one I had, have been using these from a while riding my bike during night times and it's been a wonderful experience. Avoids dust as well as the glare from incoming traffic. Must have for long rides.

Works for driving as well

I know they are meant for bike riders but you can also use them while driving so you won't get blinded by the light equivalent of a 1000 Sun's emanating from the incoming 4*4 Endeavors.

ALERT not meant for night ride,people have a misconception that yellow glass means night riding purpose this glass is only made for low light like cloudy weather,dusk,dawn time use only and is 100% uv

Storage instructions

The quality of your vision depends on taking proper care of your sunglasses. The case is not just for show! Store your sunglasses in the case to protect them from scratches, bumps and getting crushed.

Care instructions

Clean your lenses with the appropriate accessory: towelette, microfiber cloth or lens cleaner (ORAO accessory range). Avoid using paper towel, cloths that contain silicone or tissues, as they may scratch your lenses. Household products, disinfectants and acetone may also damage your lenses and their surface treatment. In the event of splashes on your lenses, never wipe them dry: rinse with clear water first.
