Yes, it is possible to have eye strain from watching TV. To have a clear vision, no matter upclose or at distance, it requires a focusing power. If keep looking at the same distance or same object, eye strain would be resulted. When people are looking at TV screen or computer monitor, they tend to blink 5 times less than normal. Without blinking, it can't help spread the tear film produced by uppder eyelids to nourish the eyeball. It can also lead to excessive evaporation of tear in eyes. Eyes are dry, and so the vision becomes blurry.Serious eye strain might cause headache. To prevent eye strain, taking frequent breaks is a good method. Changing the focusing of vision could help relax eyes. Doing eye exercises or eye massage would help promot the blood flow to eyes and so allay the fatigue.
