Contact lenses cover your cornea, significantly cutting the amount of oxygen & moisture your eyes can receive & when you are sleeping with lenses on, the oxygen supply to cornea decreases further. Without enough oxygen a state called hypoxia develops, whereby the cells in cornea lose their ability to fight bacteria effectively.
Hence it puts you at an increase risk of bacterial or fungal keratitis.
But if you still make mistake of sleeping with lenses on & you can’t remove the dried out sticky lenses easily next morning don’t tug at lenses. Instill several drops of lubricating eye drops in your eyes to wet the eyes so that the extra lubrication can dislodge the lenses.
