YIMI Polarized Photochromic Driving z87 Sunglasses For Men Women Day and Night safety glasses

The photochromic glasses with aluminum-magnesium alloy frames are designed to be worn during the day or night. The lens color automatically adjusts according to the light intensity during the day, becoming darker in stronger light, and brighter in the evening, in order to see things more clearly. When encountering high beams, the lenses soften the light without making the vision completely dark, allowing the clear visibility of the surrounding environment. Overall, these glasses are good quality and resist well, making them ideal for everyday use. They have a lightweight design and come with a nice case. However, some customers have had issues with these glasses. A few had trouble with the photochromic lens, stating that the glasses do not get very dark in bright sunlight. Others found that the glasses were too fragile and easy to break. Some were disappointed with the darkness of the lens and the lack of Z87 certification.
