Mine fitted new glasses and some other advice.
I recently returned 2 brand new laptops because the light used in the displays cause severe pain to my eyes within minutes. This must be the same lighting used in the IPads and IPhones because I cannot look at them for any period of time, either. The eye pain is likened to putting on someone else's strong eyeglasses. I have been using a Studio 1750 for the past 10 years. It has an LCD display. I understand that the light emitted from LCD is less direct and maybe that is why I can stay on it for 6 to 8 hours without any problem. I finally found an honest discussion acknowledging this problem on a website called Makeuseof.com. I only hope that I can buy a laptop with a LCD display in the future.
