Question

Why can't you sleep with your contacts in?

Answer 1

Your eyes would be deprived of oxygen, unless you have O2 lenses...

Answer 2

it makes your eyes really dry, and oxygen an't get to them.

Answer 3

b/c bacteria will grow on them and your eyes!

Answer 4

I found out after years of doing it is very harmful because it deprives your eyes of the needed oxygen which cause more blood vessels in your corneas to grow-after this happens no eye dr. will give you lens's or lasik surgery and your eyes look continually bloodshot.

Answer 5

Cos the lenses will block oxygen from going into the eyes. And dryness will set in and redness will be seen. bad for eyes in long term.

Answer 6

glass contacts will scratch your eyes while you sleep and dream.  That causes an infection when combined with bacteria from not cleaning them daily, then PRESTO! you 've got serious problems.
