1.Eye Injury
You can accidentally hurt or weaken your levator muscle. It could happen if someone or something hits you in the eye. Wearing contact lenses for many years or rubbing your eye a lot can cause it, too. Tell your doctor if the drooping doesn’t get better on its own or gets worse over time. Surgery may help.
2.Eye Surgery
Your eye might droop after cataract, glaucoma, or LASIK surgery. Doctors aren’t sure why this happens. Some think the tool that holds your eyelid back during surgery may stretch or damage your eye muscles. Surgery can also make your eyelid swell. This kind of ptosis usually gets better on its own. Talk to your doctor if it hasn’t gotten better after 6 months.
