Hello, I too have problems with sunlight and bright lights. I wear my sunglasses at all times outside and sometimes even when I am driving at night(they are prescription sunglasses) My vision continues to get worse and my opthalmologist contributes this to the dryness in my eyes. He is wanting to do surgery to put plugs into my tear ducts. He says this will keep the tears from draining out and will improve moisture. I am hesitant to do this. Has anyone had this procedure and has it helped? Thanks!
