Eye patches probably don’t help small scratches on the to heal faster. They may even slow down the recovery somewhat.

Your may become slightly scratched if a small object gets into your eye – for instance, if you get a grain of sand under an eyelid or under a contact lens. Minor superficial scratches on the will usually heal by themselves within two to three days.

In the meantime, some people cover their eye with an eye patch to keep it closed and relaxed. There are possible reasons both for and against wearing a patch: On the one hand, it might speed up the healing process by reducing blinking that irritates the scratch. On the other hand, keeping the eye closed could, for instance, make it more prone to .

Eye patches do not speed up recovery

Researchers from the (an international research network) looked for clinical studies on the effectiveness of using eye patches to treat superficial injuries to the . They found twelve studies with about 1,100 participants who had damaged their in the two days before taking part in the study. The participants were all treated with medication.

Each study compared two groups: In one group the participants only used medication, and in the other they also wore an eye patch.

Overall, the results suggest that eye patches could slow down the healing process somewhat:

  • Without an eye patch, the injuries had healed after one day in 60 out of 100 people.
  • With an eye patch, the injuries had healed after one day in 54 out of 100 people.

But the studies had some weaknesses. For instance, those patients who didn’t wear an eye patch used antibiotic ointments more often. This could partly explain why the healing process was somewhat quicker.

Also, the studies only included people with minor injuries to the . It therefore remains unclear whether eye patches could help people with more severe damage to the . The studies didn’t look into other eye injuries, such as damage caused by chemicals.
