These space goggles will help future astronauts see in space. They will help astronauts by having different types of lenses they can insert. There are many different lenses that can adjust to anyone's particular eyesight. The lenses are made of ABS plastic. They also help astronauts by having a part of them that produces light, like a flashlight. This part can easily be clipped on to the top of the glasses rim. The metal light is made of titanium, so it won't break easily. The sides of the glasses are made of titanium as well.
