This is a question we frequently get asked, typically from growers who spend a lot of time in their grow rooms or from growers who are working on a large scale. If you have ever spent more than a couple of minutes under an HPS or MH light you know that the spectrum can really mess with your eyes and over time the lights have even been known to cause headaches.
Recently at a convention we came across a company that had the perfect product for this, Method Seven. The product is indoor, grow room specific, sun glasses. In addition to making the light far more tolerable the glasses also make it much easier to see what you are working on. The picture I took doesn’t do it justice and I can’t express the how helpful it is to have clear vision when working but strongly suggest any indoor growing taking the time to check out these quality specs.
