The doctors do not necessarily need to tell you that constant time spent on your computer is harmful for your eyes as it is something which the world knows. Constant seating on the workstation means that your eyes will definitely be strained at the end of the day and you therefore need to think about alternatives that lesser the strain. One great alternative is to use LEDs to surround your workstation with ambient light. The ideal positioning of the lights should be behind the monitor or the screen as that helps reduce the strain in a considerable way.
Some inspiration can be drawn from Kevin Freitas and what he has done with his Vika Lauri table from IKEA. Kevin affixed a string of white or multi-colored Dioder LED lights from IKEA in the metal lip using sticky tape. This can really save your eyes and the added advantage is a chick looking working station.
