Can you change sunglass lenses to prescription glasses?

[Seagoville]

I have a pair of Rayban sunglasses and I really love the style. I also need to wear glasses for vision correction. So I wonder if I can change the sunglass lenses to be prescription one?

Generally speaking, it can't be changed because the off-the-shelf sunglasses are fine in work. It is difficult to change its lenses to prescription ones. I suggest you get a new pair of prescription sunglasses.

It is impossible to change the sunglasses lenses to be prescripted without replacing the lens. If you really love the style, you can keep the frame and ask the optician to put new prescription lenses in it. Most optical store can do that for you if the frame is not excessively big.
