The most important factor from which vision deteriorates due to the monitor is dry eyes, that is, if you blink more often, thereby moisturizing your eyes, you will be fine with it. Also, do not forget if you you feel that you have been sitting at the monitor a lot, you can use the methods of various exercises for the eyes that google in a minute, another important factor is the quality of the monitor itself. despite the fact that from all of the above, I only execute the item with the monitor :). Health to you!
As an additional advice to the previous ones: if you plan to read / type a lot, then make the font bigger. Since childhood, my eyesight is not perfect, but ignoring the wearing of glasses when working with small print added to everything else astigmatism from constant squinting.
When working with a computer, eyesight deteriorates mainly from the fact that you look at a stationary object next to you for a long time.
Elementary breaks and eye exercises every thirty minutes and there will be no complications.
