My distant vision started looking blurred out of my right eye.I went to my retina specialist whom had laser a retinal tear 18 months earlier.He said all looked fine,after a lot of test and pictures. The only thing he said was I had a few small hard drusens in that eye which had not change in 4 years, he did not think they were the problem.,He sent me to the doctor who did my glasses to check my prescription, he said it was right.They then did a optical coherence tomography which was normal. Bottom line they gave me dry eye drops to use which has not helped after 2 weeks using. What would you check next, could it be infammation,that eye feels it is swelling at times, PLEASE HELP
