well the directions with my ballast said never look directly ino the light, but after a wile it dosent even look that bright, but all it does is bleaches you retina (if you were to stair into it for a couple mins)which, can take up to 30mins before you can see the darkest levels of colors.
OLDJIMMYBONES Reviewed by OLDJIMMYBONES on . HPS light harmful for eyes? My friend has been growing for quite a while and whenever I enter his room where he grows, my eyes begin to hurt after looking at his babies because of the light. I am wondering if this is a concern at all if I decide to grow given I have bad eye sight already. My friend says you get used to it but he does feel like he's lost ability in his eye's pigmentation. Anyone have any ideas? Rating: 5
