Recently my vision has changed a lot. Now I'm watching a lot of dvds on my computer. And I'm also having great difficulty focusing on the text on the screen. Went to the "doc" to get fitted for "computer " glasses. I'm 59 & wearing multifocals I purchased 12 years ago. Eye exams, taken as regularly as the Ontario government agency allows, always recommended only a sight adjustment. The various "docs" said not to bother. Me (the uninitiated purchaser) & he ( the EXPERT) both failed to recognize the need to shift the eyes between a written page/document, the keyboard, and the screen. So I see the screen just fine but am pushing the glasses down to see the keyboard. (Don't even add shifting eyes to the blackboard (taking evening class.)) So off to see another doc & upgrade the multis. 1. How many focal lengths is the average multi supposed to deal with. Three? short, med & infinity? And I guess the transitions are unique to each customer? What ate the average transition numbers? Now I think I need 4. Is this normal in older viewers? 2. Does any company provide an x (glued?) on plastic/polycarbonate bubble attachment / lens that turns a monocular lens (my computer glasses) into bifocals? And should cost about ! Or do I just get another pair! thanks in advance (off to see the new guy on tuesday)
