hi dear sorry about what you are going through. Your issue may be caused by a number of things which would demand an eye exam to unravel. It could be just simple refractive error or you probably abraid your cornea from your vigorious itching or just any other thing outside these mentioned which would be revealed in the course of having an eye exam . I advise you visit a good eye clinic around you

hi dear, different clinics have different prices even for same service . The price is clinic dependent as charges isn't commodity based . I'll advise you visit clinics around you to find the cost and then you decide which you would use.

Hi Doc Good evening,please I need ur advice, I have been experiencing this ache from my right eye for over three weeks now, at times it comes with a headache and I notice that it gets worse whenever I'm using my phone(although I reduced the phone brightness to the lowest) ,system,seeing any bright colour at times walking under the sun can trigger the ache, although I visited a government hospital about a year ago and the doctor told me that it's just strain that I should watch my reading light but I don't read much now and the ache is at times excruciating,and my left eye can be itchy for Africa,sometimes when I wake up my eyes will be reddish in colour.
