Startup Idea: Health Monitor for Computer Users

Startup idea to develop software that alerts users when they've been using a computer for extended periods, potentially causing eyestrain or fatigue. The software would promote optimal computer usage by suggesting breaks and monitoring user posture to help minimize any associated physical discomfort.

A software that would tell a user that he/she has been in front of the computer screen for too long and they should take a break.

I am not sure if any of these ideas have existed before but I know that eyestrain is a huge problem and a software that could detect if the user was feeling tired or fatigued could help for optimal efficiency of the computer user.

Another monitor could detect proper posture of the computer user to help minimize back pain. I did not try finding a solution the only solution to this now is to force myself to take breaks.
