Has any body been growing cmh lights for 5+ years and have eye damage?

yes those lights arent good.. i got lil yellow growths on my eyeballwithin a few weeks of just going in to do watering etc. similar buildup damage from sun and snow. thankfully they go away if not too severe. i have a 630 cmh ballast and bulb f/s if anyone wants that junk.

I grew using old 4000k Philips CMH and incurred Welder Flash several times, nothing with HPS or LEDs even those with decent UVA diodes. Like fine dust in the eyes for a couple days with watering.
