Hello. I am going to gym from the past 1 year and my Eye power seems to be increasing every 3 months. I sit in front of my PC and work. I also work late night. Is that the reason? How can I protect my eye? I already wear glasses. Secondly, I wanted to get my eye laser surgery done. How effective is it? Can I undergo this? My age is 20. But my power keeps changing. My doctor said me that the eye power can change because I workout and become thin. Please suggest me about the laser treatment and also my increasing eye power and solution to siting in front pc for longer period. Any gadget or glasses I need to wear? (i already wear my power glass) Please reply Thank you.
