I'm a Engineer and graphic designer, I spend thousands of hours in front of computer work stations, and many more thousands of hours surfing the intranet. I have never had dry eyes, burned and tired yes but can't say they have been dry enough to need drops on a daily basses or any related product, even contact lenses without problems. Yes sometimes we just need to get out from in front of that screen and get some rest, our body's are pre- 20th century and and we are using them to do post-21st century work, it's not a good match.
I guess you can blame just about anything on Diabetes, I would blame it on not enough sleep, multitasking, environmental, HVAC, pollution and smog. Where you live can have a impact, a big city, or in a place with a lot of Agra industry.
I have many things I could blame on Diabetes, many of my family members have the same issues, but what do they blame it on... "they are not Diabetics".
