Then we went to the opticians. He tested me loads, both eyes. Basically I am slightly short sighted on my left eye but there is no point giving me glasses which will sit on the shelf as I don't need to drive and he mentioned how it will actually help me seeing the Computer and my Kindle. My right eye is long sighted but as it is usually under a black thingy there's no point being concerned. And he said continue wearing the black thingy to prevent double vision
