I doubt radiation is the main cause for short-sightedness. There are also other factors such as improper lighting condition and glare which also applies to LCD and plasma Televisions. That said, the latter do have an advantage over CRT in the area of flickering images. This problem can induce eye strains in older non-100Hz CRT Televisions.
