Is It Really That Bad to Sleep or Shower In Contact Lenses?

No — it is absolutely not safe to wear contacts while sleeping (unless specifically approved for overnight wear) or while exposed to water. Here’s why.

Why Sleeping in Contacts Is Risky

Your corneas need oxygen and hydration to stay healthy. Sleeping in contacts limits oxygen flow to the cornea and reduces its ability to fight bacteria, making infections much more likely. This can lead to corneal abrasion and, in serious cases, permanent vision loss.

Why Water and Contacts Don’t Mix

Any water source — tap water, pools, lakes, or showers — can contain bacteria and microorganisms that get trapped under contact lenses against the cornea. This increases your risk of microbial keratitis, a serious corneal infection. Even brief exposure can cause contacts to change shape and stick to the eye, potentially causing scratches.

Eye Care Tips for Contact Lens Wearers

• Always wash and dry hands thoroughly before handling lenses
• Remove contacts before showering, swimming, or bathing
• Never sleep in lenses unless they are specifically approved for extended wear
• Follow manufacturer and eye doctor instructions for cleaning and replacement
• Store lenses in fresh solution only — never reuse old solution

If you experience eye pain, discharge, or sensitivity to light, remove your lenses immediately and contact Miamisburg Vision Care in Miamisburg without delay.
