"I think you are pretty clever!
If the eyeball is too long and the clear image is created in front of the retina, it is called shortsightedness.

"By the way, both shortsightedness and farsightedness can be compensated by lenses. If you add a frame to a pair of lenses you will get glasses and if you have lenses made of very thin plastic foil they are called contact lenses."
Now you surely have an idea how to solve the brain teaser's question from the beginning!
