Removing 23 forgotten contact lenses - GIF

[Gadgeteer]

Having never worn contacts I can't even begin to imagine having 23 of them in my eye socket. How can that not become painful long before that many were lost inside. Maybe the eyes become desensitized over time

This is a great example of the success of gas permeable soft contact lens material that can be worn and tolerated by eyes without aggravating eye tissues. Fortunately, the tissue in the white (sclera) of eyes has ample underlying blood vessels that provide cellular nutrients and oxygen. Since the cornea is, normally, devoid of blood vessels, it gets oxygen dissolved in tears when our eyes are open. During sleep, oxygen for corneal cellular requirements is dispersed by blood vessels in the tissue underlying eyelids.
