I have high myopia and I try to keep my eyesight as best I can. I take vitamins, do exercises for the eyes, use special glasses for working at the computer. I completely agree with doctors that proper lighting is very important for eye health. I know that lighting affects eyes and mood a lot. Here you can get more information. From the cold yellow light you will be more active, focused and awake, at the same time with such lighting you will be more difficult to relax and fall asleep. Such lighting is perfect for the kitchen, living room or office. Warm yellow light is perfect for the bedroom, but if you don't like to read before bedtime. For work or reading, I use a cold-light desk lamp.Also don't forget about the breaks from work for 10 minutes every hour. This is very important for good vision.
