Review on 🕶️ Bertoni F188PH Photochromic Aviator Motorcycle Vintage Goggles: Stylish Sunsensor Black Leather Glasses for Helmets by Eric Trask

Works great I first tested it on a cloudy day and it sucked. However, I correct myself. The manufacturer wrote to me and said they react to ultraviolet light. The higher the UV value, the darker they darken. Today was a bright sun, they changed quickly. They don't change with a flashlight or indoor lights like my glasses, it has to be sunlight. I take back my negative review and give them 2 thumbs up.
