Boston IN/OUT Sunglasses - Gray Lately, work styles have been changing, with more people working from home or remotely. The time spent staring at PC and smartphone screens has also increased, and I think the strain on the eyes has also increased. When you go shopping nearby, you can go out as you are with these glasses. They react to ultraviolet light, gradually changing the lenses from clear to gray, transforming them into sunglasses. The rounded, inverted triangle frame shape will fit your face line and give you an intellectual impression. They are 2-WAY eyewear, functioning as blue light-blocking glasses indoors and sunglasses outdoors.
