Contact lenses come with different shapes, colors and sizes. There are two kind of contact lenses such as: eyesight lenses and none eyes sight lenses. Contact lenses are affordable and usable. People these days can easily find it at optics and shops.
It sounds like it is normal but it is abnormal after you hear about contact lenses in 1948. It may makes you scream without knowing after seeing the video shows how it made of.
Do you want to try 1948 contact lenses? To me; if you rent me hundred dollars or thousand dollars or even more, I would not try it. My eyes are worth than your money.
