First it depends on what kind of PC you’re buying. LCD displays are very cool and smooth in picture quality and won’t hurt your eyes. So you don’t need screen filters also those are easy to adjust to your viewing needs. It will be way better than CRT make sure you buy one from a better brand like view sonic. You need once for cool prizes try one from the view sonic VA series which offers the best pictures colors resolutions for the money your paying .if ur buying a new computer it may include a monitor or a LCD.
