Loss of sight depends on many causes. It may be sudden and temporary, or it may be permanent. Of course a medical man will be consulted to decide this. If it is accompanied by great pain and hardness of the eyeball (Glaucoma) immediate treatment, by operation, possibly, is demanded. Blindness may occur apart from any real change in the eyes, and in such cases, as well as in some where there is actual change, medicines may be very efficacious. They should be given frequently (every hour) until benefit is perceived, then less often.
