How many hours a day should you wear contact lenses?

It’s always best to speak with your optician regarding how you wear your contact lenses and how long you should wear them for. However, general practice goes that you shouldn’t wear most contact lenses for longer than 10-12 hours a day.

The problems posed by wearing your contact lenses for too long include discomfort, drying of the eyes, blurred vision, redness of the eyes and increased chances of an eye infection. If you experience any of these problems, you should consult an eye care professional immediately.

What happens if I don’t change my contact lenses every month?

Failing to replace your lenses when required can cause your cornea to swell and lead to corneal abrasion, dry eyes, red eyes and an overgrowth of blood vessels which in turn can cause irreparable damage to your cornea. If you wear yearly contact lenses, then you don’t need to worry about replacing them every month, so long as they are cleaned and stored effectively.
