Contact lenses can cause eye pain if they are worn incorrectly, for too long, or without proper hygiene. Doctors usually point to these common reasons:
Why contact lenses cause eye pain
- Dry eyes
Contact lenses reduce oxygen and moisture reaching your eyes. This can make eyes dry, irritated, and painful. - Wearing lenses too long
Using lenses beyond the recommended time (especially overnight) strains the eyes and causes discomfort. - Dirty or infected lenses
Not cleaning lenses properly allows bacteria to build up, leading to redness, pain, and even infection. - Wrong lens size or type
If lenses don’t fit your eyes properly, they rub against the cornea and cause pain. - Dust trapped under the lens
Small particles stuck under the lens can scratch the eye surface and cause sharp pain. - Using expired solution or lenses
Old solution loses disinfecting ability and increases the risk of irritation. - Allergic reaction
Some people react to lens material or cleaning solution, causing burning and watery eyes.
Doctors’ correct way to use contact lenses
- Always wash hands before touching lenses
- Clean lenses with fresh solution, never water
- Do not sleep while wearing lenses (unless prescribed)
- Follow wear time (daily, monthly, etc.)
- Replace lens case every 1–3 months
- Remove lenses if eyes become red or painful
- Give eyes breaks by wearing glasses sometimes
- Never share contact lenses with anyone
When to remove immediately
Take lenses out right away if you notice:
- Sharp pain
- Redness
- Blurred vision
- Watering
- Light sensitivity
