I suffer from headaches when concentrating at a distance, e.g. when driving and looking at a projection in lectures. This is happening almost daily. The headache is behind my right eye. I am short sighted and wear contacts. I have visited the optician and my prescription is fine, but they noticed I may have a blind spot in the upper, outer field of vision in my right eye. Could this be the cause of my headaches and is there a soloution?
Many thanks.
