I had left eye irritation for 20 days and had blurred vision in the same. So I consulted an ophthalmologist and after check up and he told me that it may be because of some allergy and prescribed me with two eye drops for one week. Also he said that I have minus 0.75 power. It has been a week and now I feel better with the irritation. But sometimes I feel like my left eye gives blurred vision and sometimes like it gives normal. What is the reason? What is the solution?
