Have you ever wondered that trading can be bad for your health?
The first problem you can have is - eyes problems. Spending more time in front of your computer can be harmful to your eyes.
The second - stress. Stress can cause many problems from high blood pressure to depression.
I am really sorry to see your condition being deteriorated by the stress you are under while trading, you must have a limit on everything you do if not you will be under stress, i am not sure spending more time in the computer will harm my eyes as i am spending more hours in front of a system for the past 25 years and i am a healthy person with no eye problem, yes stress is an issue when ever i gamble or trade earlier, but with age you will learn to overcome those.
