My problem is that whenever I watch tv, use a mobile phone or laptop my left eye becomes blurred. Even if I watch tv, phone or laptop for 5 minutes my left eye becomes blurred. My right eye remains normal. Then it (left eye) takes 15-20 minutes to become normal. I can't understand what is the reason. Should I use some special glasses while using a laptop, mobile etc. What should I do? Extra information: a few weeks ago I underwent medical examination (of the army) and eye specialist wrote some readings for my eyes (i don't understand these readings). For right eye, he wrote 0 and for the left eye, he wrote +0.25. And the eye specialist declared me fit.
