I'm not sure, but I think that its your skin that protects the internal tissues.
I actually have that problem. I have 20/40 vision and my left eye is pretty much blind. I was prescribed glasses so that my sight in my left eye would not get worse. All to say, I would consider glasses to be necessary in this case. It definitely helps in every day life.
I hope this helps and have a great day!! :)
