My medical tool is very useful. It is basically sunglasses but better. They are called Dark Glasses. These glasses help prevent someone’s eyes from the sun. You’ll probably thinking it’s the same thing as sunglasses. But they aren’t. These glasses are specially made for being extra close to the sun. The lens are made very dark so when you look through them on earth, you’re lucky if you see anything. When you’re up in space, they will be just like sunglasses. Basically you put them on like sunglasses. The lens is made out of a really dark plastic. The sides of it is made out of solid plastic. This can be helpful because when you are orbiting the earth you will eventually see the sun at one point. For something that bright, you’re going to need something to protect your eyes. This is why my tool is very helpful.
