I asked my eye doctor about this a couple months ago. For context, I was getting an updated prescription and have no major health or vision problems, so I would assume the advice is probably applicable for other generally healthy people in their late 20s. I also spend about 90% of my waking time on computers, which I mentioned to him, thinking that I might need to do something special to take care of my eyes. He told me that he thinks computer glasses are marketing fluff, and suggested that if my eyes are feeling strained or dry, I could just use regular moisturizing eyedrops. Besides that, he suggested maintaining generally good physical health and a healthy diet. Disclaimer: if your eyes are actually bothering you in some specific way, please see an eye doctor. Or if you have mild hypochondria, just see a doctor and ask; there's no harm in asking. Otherwise, if you're young and generally healthy and have nothing wrong with your eyes that you can discern, there's probably nothing specifically about your eyes to be particularly concerned about even if you use a computer 12 hours a day. Your cardiovascular health, on the other hand, would probably be something to watch.
