How old are you? I know at 83 my eyesight has deteriorated so that I no longer read books because of eyes strain, also watching the 55 inch TV can become blurry, it's actually better to watch a smaller screen like a 42 inch. Had eyes checked several time at Bkk/Pattaya hospital, once was told needed a cataract op, next time a different doctor said my eyes were OK. Who do you trust?
