Can I use artificial tears like tears naturale II eyedrops (from alcon) everyday to prevent dry eyes. I'm an it engineer & I always use computer.

Dry eye. Tears naturale (artificial tears) is safe for the eyes. They can be used every 1 to 2 hours for dry eye, if needed. Remember to take frequent breaks when using the computer for long periods of time. Alternate choices include systane and theratears.
Yes. artificial tears with preservatives can be used daily up to 4 times a day. In my patients who need them more often I recommend preservative free artificial tears. Also, you can consider other treatments like restasis, punctal plugs, etc... a good ophthalmologist should be able to help you choose what is best for your eyes after doing an eye exam. .
