Airontek glasses, indispensable for those who grow indoors and want to protect their eyesight from the harmful rays of HPS or LED lamps; these rays are excellent for our plants but are very harmful to our sight (it would be like looking directly at the sun).
Airontek glasses filter the light protecting our retina, but they are also excellent for filtering the coloration of light and for seeing the real colors of our plants. They are also sold with two pairs of lenses, those with the filter for HPS lamps and those with the filter for LED lamps.
If we want to spend time in our greenhouse with lights on, these glasses are practically mandatory.
