Noninfectious keratitis
Keratitis can also be gotten from noninfectious ways, some of which include:
- eye injury, such as a scratch
- a weakened immune system
- wearing your contacts too long
- wearing your contacts while swimming
- using extended-wear contacts
- living in a warm climate, which increases the risk of plant materials damaging your cornea
- exposure to intense sunlight, called photo keratitis
If you start treatment early, you’ll likely start feeling better after one or two days, whether it is anti-infective medication you are taking or other treatment. Recovery will take longer for more severe cases.
