Is It OK to Sleep in Biofinity Contacts?

Yes, Biofinity contact lenses are approved for extended wear, including overnight use for up to six consecutive nights and seven days. This approval comes from both the manufacturer, CooperVision, and the U.S. Food and Drug Administration (FDA).

Biofinity lenses are made from silicone hydrogel, a material that allows more oxygen to reach the cornea compared to traditional hydrogel lenses. This increased oxygen permeability is important because the cornea receives less oxygen when the eyes are closed during sleep. By allowing more oxygen to pass through, these lenses help maintain corneal health during extended wear.

However, not all eyes tolerate overnight lens wear equally. Potential risks associated with sleeping in contact lenses include:

• Corneal infections: Sleeping in lenses can increase the risk of bacterial keratitis, a serious eye infection that can lead to vision loss if untreated.
• Reduced oxygen supply: Even with high oxygen-permeable lenses, extended wear can still limit oxygen to the cornea, potentially causing complications over time.
• Dryness and discomfort: Some users may experience dry eyes or discomfort after sleeping in lenses, even if they are designed for extended wear.

Given these risks, it's best to consult with your eye doctor before deciding to sleep in Biofinity lenses. They can assess your eye health and determine if overnight wear is suitable for you. Even if approved, it's advisable to remove your lenses before sleeping whenever possible to minimize potential complications.
