Then, outside in bright sun, a grow-room lens is no help at all. Many growers end up juggling two pairs, or going without. A transition lens covers both: colour correction under the lamps and a proper sunglass tint outdoors.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnder HPS\u003c\/strong\u003e: wear them whenever the lamps are on and you are working in the room.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutdoors\u003c\/strong\u003e: the lens reacts to direct sunlight on its own – allow a few minutes for it to darken fully.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack indoors\u003c\/strong\u003e: give the lens a little time to return to its blue HPS tint before close inspection work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot for LED rooms\u003c\/strong\u003e: under full-spectrum white or blurple LEDs, choose a Method Seven FX or LED lens.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClean with a soft microfibre cloth\u003c\/strong\u003e and keep them away from lamp heat.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Method Seven Evolution HPSx Transition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens:\u003c\/strong\u003e HPSx colour-balancing lens with photochromic (transition) layer, polycarbonate blend\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTint:\u003c\/strong\u003e blue HPS tint indoors; darkens to dark grey in direct sunlight within a few minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection:\u003c\/strong\u003e UV protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesigned for:\u003c\/strong\u003e HPS grow rooms and outdoor wear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame:\u003c\/strong\u003e Evolution, TR-90, matte black, concealed flex hinges, made in Italy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e lens width 54 mm · bridge 20 mm · temple 130 mm · Base 6 curve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e average to large faces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot for:\u003c\/strong\u003e full-spectrum white or blurple LED lighting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cdiv class=\"hcs-faq\"\u003e\n\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eHow quickly does the lens change?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eIn direct sunlight it darkens fully within a few minutes, from its blue HPS tint to a dark grey sunglass tint.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eWill it darken under my grow lights?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eThe transition is triggered by direct sunlight, so in the grow room the lens works in its blue, colour-balancing HPS state.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eCan I use these under LED grow lights?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eNo. The HPSx lens is tuned for high pressure sodium.
