LCD easier on the eyes than CRT

yes ive done a search. Anyway, I have switched ALL of my CRT's to LCD's because I hear there easier on the eyes. Whats the reason for this and is this a longterm/shorterm thing? Thx in advance

lcd = always on, only colors change
crt = strobed 60-120 times a second, whatever your refresh rate is
