Seek a second opinion with an ophthalmologist. Severe headaches should not result from resolved conjunctivitis. The ghosting may be a refractive issue, even though you measure 20/20 on the eye chart. There could also be some higher-order aberrations in the cornea causing the ghosting.
Actually my work invloves working 10-12 hours in front of the computer , that is what causes headaches without work I dont get them . and I also did the pin hole test and found out that I dont get ghosting while looking through the hole . doctor has given me a prescription of cyl -0.5 axis 180 , but I even get more headaches by wearing that actually by wearing those glasses it feels like my facial muscles are streched, I am scheduling a appointment with cornea specialist this week . Do you think RGP lenses might help me .
