What happens when you put on contacts when you don't need to?

Wearing contact lenses when you don't need them can cause discomfort, dryness, and irritation to your eyes. It may lead to blurred vision if the lenses have a prescription that doesn't match your eyes. Additionally, improper use can increase the risk of eye infections or complications, as the lenses can restrict oxygen flow to the cornea. It's essential to use contacts only as prescribed by an eye care professional.
