Pinhole glasses

Hey kiddo! Have you ever heard of glasses that don't have any lenses in them? These special glasses are called "pinhole glasses."

So how do pinhole glasses work? Well, when you put on regular glasses, it helps to focus the light coming into your eyes. This lets you see things more clearly. But what happens if you can't afford regular glasses or you lost them somewhere? Pinhole glasses can be a cheap and easy solution!

Pinhole glasses have tiny holes in them where the lenses would normally be. When you look through these holes, they help to reduce the amount of light that's entering your eyes. This makes the image you're looking at appear sharper and clearer.

Think of it like looking through a little peephole to see things better. The holes help to limit the amount of light that comes in, so it’s easier to focus on what you want to see.

So pinhole glasses are a helpful tool for people who can't afford or don't have access to regular glasses. Remember though, they're not a substitute for eye exams or proper eye care.
