Have specs and I have front viewing weak vision. During normal days my vision is fine and I am able to see without any problem, I do not wear specs constantly. At the time of office work load or long study hours my vision gets blurred, I cannot see things properly. Word full page seems as if it is blank due to which I am not able to focus at things properly. It has been around 4-5 years since I am suffering this. I have consulted an eye specialist many times and each time I got a new pair of plus power and this did not worked out for me. Due to this prolonged suffering the things had become worse, now even if think that my vision would get blurred suddenly I feel change in the shape of my eye lens and the vision gets blurred instantly. What shall I do, I am in deep trouble as my exams are near and I am not able to study at night, during the day time in sunlight I am able to study and focus but not for too long and during the night I am unable to study at all. Please help.
