(1) Dim the lights:
You want your computer screen to be the brightest thing in the room. You want your office space to have as few ‘bright spots’ and as indirect shining on you as possible.
(2) Reduce glare:
Glare usually means there is one spot on your screen that is particularly bright. Your eyes will have trouble adjusting to the brightness of the glare with the rest of the screen which can result in discomfort.
(3) Minimize blue light exposure:
All electronic devices emit blue light and you should definitely avoid exposing yourself to blue light at least 2-3 hours before bed, as it disrupts your circadian rhythm. You can try programs like flux which adapts the color of your computer screen to the time of day.
(4) Follow the 20-20-20 rule:
Look away from your computer or screen every 20 minutes and focus on a distant object at least 20 feet away for at least 20 seconds.
(5) Make your workspace eye friendly:
Most of us have our desks setup completely wrong. Rule-of-thumb is that your eyes should level with the top of the screen. Try this website to help you figure out how to optimize your workstation to protect your eyes.
(6) Take vitamin-A:
Retinal is processed vitamin A, and retinal is essential to the process your rhodopsin (also known as visual purple, a biological pigment in our eye's photoreceptor cells of the retina that is responsible for the first events in the perception of light) goes through when you perceive light. The average human needs between 700-900 micrograms or 5,000 International Units (IU) of vitamin A every day.
Sweet potatoes, carrots, leafy greens all have high levels of vitamin A in them, so get to noshing.
(7) Listen to what your eyes try to tell your:
If your eyes feel tired then they are tired! Don’t try to write off eye fatigue as something else because like most health issues, this one isn’t likely to get better when ignored.
If you feel eye strain or headaches, take a break. Try blinking slowly for ten times to re-wet your eyes. You can also trace a figure-8 pattern with your eyeballs, and cup or palm your hands over eyes. The idea is to give your eyes some variation which can provide you with some relief.
