Can you wear the wrong contact lenses? new study investigates
NCT ID NCT06745375
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether wearing contact lenses with a prescription that is slightly off (within 2 units of the correct power) still provides good vision and fit. About 38 healthy adults who already wear contacts will try two different lenses. The goal is to see if these off-prescription lenses could be a safe backup option when the exact prescription is not available.
