It is said that glaucoma is one of the main causes of blindness in the United States. While anyone can get glaucoma, some people may get it over age 40, everyone over age 60. Kid, you can tell your grandpa that he needs an eye exam timely. I think only the doctor can help him at this moment. Eye drops are usually prescribed for treating glaucoma. Before using it we should wash our hands. And hold the bottle upside down.
