So its summer-time and you’re at the beach.

Friends challenge you to a game of volleyball.

There’s only one problem: you can’t see the ball too well if you’re wearing your sunglasses and if you wear your regular eyewear then the sun gets to you.

Solution: prescription sun glasses

In the past few years, prescription shades have dawned heavily onto the eyewear market.

By prescription, it is means lenses that are measured to let you see clearly (be it from your myopia or far-sightedness) and still protect your eyes from the harmful UV rays of the sun, while shading them from the extreme light.

Mostly made of plastic, prescription sunglasses can be custom-made to suit your tastes in style of frame, tints, size and of course, lens prescription.

Except for wrap-around sunglasses, nearly any and every pair of sunglasses can be converted.

This is because prescription lenses usually distort vision when curved.

As an alternative, there are also these things called ‘clip-on sun lenses’ that can be attached to your normal prescription eye gear.

But they can get quite problematic since you might either just misplace them or find it too much trouble to clip them on and off everytime you go out.

But for some people, it can be a little expensive to carry two pairs of prescription glasses around.

Or, they simply find it troublesome to bring out more than a single pair.

For them, photochromic lenses might be the answer.

These are a form of prescription sunglasses, where the lens ‘changes’ to adapt to the changing environment.

So indoors, they are normal prescription glasses and outdoors they tint to offer you darker shades like sunglasses.
