Jasif, just pay a visit to all malls and all optics in them. Most probably you will find nice models/brands and prices as well.

But of course in the end it will depend on your budget and what model fits you better.

In city center you have like + 6 (maybe more)places that sell sunglasses

Just check out!!!!

Good luck!!!
