Interesting.. When I'm on sugar rush, my phone screen starts flickering. But just to me - noone else. Could be high blood sugar increases eyes' photosensors' refresh rate.

Could explain why lots of devs are troubled by 60hz monitors while others aren't

@jespersh I'm not a diabetic, but thanks for the ref.

@netikras well, if you're experiencing "sugar rush" regularly enough to notice such effects, the correct phrasing would be "i'm not a diabetic - yet"

@tosensei only when I have too many sweets :) yes, regularly: every easter, christmas and my b-day :)

When 60Hz monitors were CRTs they were really easy to see flicker. Now the new LED monitors have a much longer fluoresce and does not flicker as much. Even 30Hz isn't as bad. I have a TV that refreshes at 30Hz and I cannot perceive any flicker. But the old monitors were terrible for some reason.

That is interesting that you can see this with modern screens.

@Demolishun it passed after 20 minutes or so...

Im diabetic, type 1, and when it was starting I almost got blind, when my sugar is high I have pain and some troubles to see.
It's better you look for a doctor to do a checkup, I got it with 23 years old and in my top of my body performance (at least I guest rsrs)

Mobile phone screens could be affected by PWM / pulse width modulation.

A high sugar intake can affect the bloodpressure.

@jespersh LOL

First see a doctor

Also check the blood sugar

Fasting (also 3 month average HbA1c)
After food
Random

Do it while happening also.
