People like me that work on computers for long hours often complain of eye strain. It was because of this eye strain that I decided to go for a new face for my computer. Yes I sold my old CRT monitor and bought a new LCD TFT monitor for my computer display. I have bought Acer AL1916W 19 inch wide screen monitor for my usage. I can observe irritation level in my eyes going down dramatically. I wish I would have made this decision earlier. There are two reasons for this observation; firstly LCD monitors do not release harmful rays/radiations that CRT monitors are known for. This is the exact reason why people were advised not sit in front of computers for longer duration.
Secondly since this monitors are ultra thin they hardly occupy any space on your computer table and thus increase the distance between the eyes and monitor thus automatically reducing any chances of eye straining. This increases the duration for which one can sit in front of the computer and also increase the efficiency of work done.
The most important thing that propelled my decision towards buying a LCD monitor is the beauty of LCD monitor. It just makes your house look complete and somewhere I think it also enhances the performance of computer, may be my CPU likes to have beautiful monitor helping him out.
