Hi,
Gunnar seem good but then any lens that has an anti-reflective coating on them will suffice in reducing eyestrain and glare not only from a computer screen but also while you drive at night. The main function of these lenses are to neutralize the splitting of white light when it hits a surface into its component 7 colors (vibgyor). An anti-reflective lens will aid in neutralizing the spillitn up of white light and allow pure white light to enter into your eye thus reducing strain.
I would suggest you visit an optician and ask him for any good AR Lens this can be from Zeiss, Essilor Hoya etc all these 3 companies have excellent anti reflective lens coatings.
I have been in the optical industry for the last 17 years and i can vouch for those lenses.
