Sleeping with Contact Lenses

Sleeping with contact lenses significantly increases the risk of infection.

Poor Contact Lens Hygiene

Improper cleaning and storage of lenses is one of the leading causes of eye infections.

Risky habits include:

• Reusing old contact lens solution

• Not replacing lens cases regularly

• Wearing lenses longer than recommended

These habits allow bacteria and microorganisms to grow, which can lead to serious eye infections.

Always follow the recommended wearing schedule provided by your eye doctor.
