Grow rooms have lots of light, but it's not broad spectrum. Though this might be great for plants, it's not so great for your eyes. Human eyes contain rods and cones, which need broad spectrum light in order to focus, recognize shapes, register movement, and see color. In a grow room environment, sunglasses make things worse by darkening all the light, so you squint less, but you still can’t see color, and it’s even more difficult to focus. Other grow light glasses attempt to color balance the extreme light spectrum but use cheap plastic lenses with very poor clarity that distort light and are hazy or blurry.
With cheap grow room glasses, your eyes and brain work overtime to compensate. This leads to fatigue, headaches, seeing spots, and in some cases, experience damaging UV radiation. Your eyes are essential, and so is getting the most out of your grow. Don’t risk using sunglasses or cheap grow room glasses!
