answer:It could be the prescription is a little strong for you. If I have the prescription that’s apparently right for me, I can’t read my computer properly so they have put in lenses based on my old prescription. I spoke to my eye specialist who is an eye health guru and he said eye tests ‘are subjective you know?’ Perhaps try getting another test with another doctor and see if the prescription is the same. Also, think about whether you have changed something in your life. Are you sleeping the same? Doing the same things? Have you been using your computer more? Could your eyes be tired? How’s your diet? No other health issues? Your eyesight can be affected by other things like blood sugar levels for instance.
