Blepharitis is an inflammation of your eyelids. It can make your eyelids red and eyelashes crusty, and make your eyes feel irritated or itchy.
It can also lead to burning, soreness or stinging in your eyes. In severe cases, your lashes may fall out, and you can develop small ulcers or styes as well. You may find your eyelids become puffy. The symptoms tend to be worse in the morning and when you wake up you may find your lids are stuck together.
Blepharitis is a chronic (long-term) condition. This means that once you have had it, it can come back even after it has cleared up. It normally affects both eyes. You can usually treat it by keeping your eyelids clean. You may need to do this for several months.
