My ophthalmologist recommends not using eye drops long term (except possibly artificial tears), unless you are treating something.

One of the most effective tactic is to not stare at your monitor all the time. Close your eyes or look outside a window between your pomodoros.

Get your eyes checked and make sure you have the right lenses if you need any.

Definitely sleep more.

Don’t work on a bright monitor (or playing with your phone) in darkness. Always work in a well-lit environment. A quick test is to place a piece of white paper beside your monitor, and your monitor should be as bright as the paper.

Keep your monitor at the right distance, roughly at arm’s length.

Mine had a similar recommendation about eye drops and additionally strongly advised me to never use drops with vasoconstrictors like Visene.

A better solution for redness is asking them to prescribe you some NSAID like Ketorolac (generic) or Prolensa (brand). Tell them your eyes get red/inflamed sometimes and they should give it to you. Very safe drop to even use for a few weeks straight so it's a great to have around for say a party/date/event where your eyes are bloodshot for some reason.

Of course if you have pain or feel something is wrong do not use this to mask it, go in for a check.
