My mother has Glaucoma. It's easy to treat with eye drops, but if you don't treat it , you can ultimately lose your sight. It's caused by a build up of pressure in the eye. Daily eye drops needed.
YOU should also now have regular eye checks, because glaucoma is hereditary. You will now get free eye checks because a close member of your family has glaucoma. you must remember to tell the optician this.
