How much do prescription sunglasses usually cost?

[Gotham]

Ive been thinking of getting some prescription sunglasses for a while, and now that its summer, i wanna be wearing sunglasses, only problem is that i use prescription eyeglasses, i used transition glasses, and i just hate them. So, around how much do prescription sunglasses usually go for? Im not looking for an exact price, just an estimate. I dont want high end Dolce Gabana glasses, just something simple. Im in California, if it helps.

It varies on different factors. Many lens options such as high density, UV coating, transition, and other package options can drive up the cost of a lens dramatically. If you just want a pair of ordinary prescription sunglasses, you can get it under $100 easily. If you want designer sunglasses, it can be as expensive as you can imagine.

It varies tremendously and it pays to shop around. I buy mine online at http://www.eyewearcanada.com/ with only $45, you won't get much cheaper, and the quality is the same as the expensive ones.
