I had headache for a week  then i went for checkup and when i saw the hut in machine that was little dusty to me not very clear like hd like it was before but when i had to read letters i was able read them all but again dusty then dr gave me different lenses with those the difference was it was more clean and clear. But i had doubt and didn't want to put on spectacles because i was able read them all though with specs they seem more like high quality and my power was .5 for right and .75 for left but when i went to another opticians and told him everything he said if you are able read all letters in test then you don't need spectacles because spectacles can't be prescribed just for clearitiy.  now i am more confused whether to wear  or not because they actually give me clearitiy but without specs also i can read also he asked if i had any problem after using but i faced no such problem for a day or two i felt little pain but it didn't last long. should i continue using specs or not ?
