Will I go blind from computer usage?!

Will I go blind from computer usage?

I am 27 years old. Between 1997 and 2005 I would say my prescription was the same (-6.50 & -6.00 ). During the last two years I have been working behind the computer a lot more frequently because of my job.. I went up to a -7.50 right eye & -7.00 left eye. Ok so it freaks me out a bit cause I am already as blind as a bat. So is the computer going to continue to make me blind? I don't have to be on it all the time at work frankly I seldom have work to do.. I am just bored as hell like I am now and think using the computer is the best way to at least pretend that I am actually working. I wear contacts during the day and glasses when i get home by the way. I have considered lasik surgery but right now I am trying to buy new furniture for my apartment so it's not in my budget.

Because you are staring at a computer screen, your eyes for the most part, do not blink unless you look away. That causes eye strain. Add to the fact that the monitor screens (even the latest ones) are found to be harmful to the eyes, especially when looking at it in the dark, it can lead to blindness in the long run.

Blinking is important to keep your eyes at rest and fully focused. So try to have your eyes blink at least once every three minutes (better if you can blink once a minute). Also, try not to stare at the computer for too long and allow your eyes to rest and focus something else, such as reading a document in your office space or doing paperwork by hand. Seeing that you use the computer all day, it's suggested that you leave your computer for 15-30 minutes for every 3 hours you spent working on it.
