Where should I get prescription sunglasses?
I’ve just gotten them from my regular optician — it’s just like applying a tint to plain ol’ prescription lenses, except the tint is a lot darker The tint can actually be any colour or darkness, they’re just dyed lenses, if you have a pair that you find to dark take them back its a simple and quite fast job to remove a tint completly or partially.
Some designers provide Rx adapters for sunglasses. There’s also eyeglasses.com, which provides custom frames in addition to tinting and polarizing services.
