Is this just FUD? I've been using contacts and doing coding for over a decade now. I get my annual checkup from the eye doctor. They would know if my eyes were getting damaged, wouldn't they?
Anecdotally, I've yet to find a pair of glasses that lets me function in the world as well as contacts. (My eyesight is poor enough that I cannot see the screen on my phone with both eyes open, as it has to be so close to one eye that it is too far from the other.) Wearing contacts lets me see the entirety of my world, not just the portion within the frame of my glasses.
The natural blink reflex can be supplemented with an external reminder, similar to alarms that remind you to stand for a few minutes, or focus your eyes at infinity to balance out the close monitor.
