U can try Usj Optometrist, just tell them u are lowyat member or recommend by me. They will give u better discount.
U should go for Varg eyewear, same concept as ic berlin but much cheaper price and its made of beta titanium that is flexible and super light weight. Usj optometrist has them on sale now, much better quality.
U should try carl zeiss new lens called drivesafe which comes with special coating mainly for drivers.
Oakley and rayban frame can be made into sunglasses. U can check them both in Usj optometrist.
Oakley got special edition which is cheaper, less than rm 800 can get together with multicoat lens, if ur power is low, can even get blue control lens but u need to go my friends shop la in subang jaya taipan, Usj optometrist.

U can order the replacement part for your oakley frame also.
