I have shortsightedness and using -0.75 prescription glasses.Am recently experiencing problem of double images of objects which are at distance about 5-6mts away and with computer and mobile screen. Recently I visited an doctor after examination I was told that it is an minor problem and no need to worry but it's causing problems like loss of concentration and difficulty in seeing thing, doctor prescribed-1.0 power glasses recently. Should I see one more expert or should I neglect that???
