Polycarbonate optics have a high impact resistance, which makes it much tougher than traditional glass or plastic lenses. Additionally, polycarbonate lenses are typically thinner and lighter while also boasting excellent optical clarity and UV protection. Overall, this makes it a practical choice for a variety of optical needs.

Photochromic lenses can not only protect against the sun when going out, but also be used indoors. It combines sunglasses and ordinary lenses in one, which is more convenient. This lens has a very good visual effect both indoors and outdoors. After the lens changes color, it can be used as a sunglasses, and the depth of the color will change with the change of light intensity. The stronger the light, the darker the color. After leaving the ultraviolet environment, it will return to a colorless state and can be used as an ordinary lens.
gray lenses can absorb infrared rays and ninety-eight percent of ultraviolet rays. Its advantage is that it will not change the original color of the scenery due to the lens, and it is satisfying that it can effectively reduce the intensity of light. Gray lenses can absorb any color spectrum evenly, so the scenery will only become darker when viewed, but there will be no obvious color difference, showing a real and natural feeling. Gray is a neutral color that suits everyone.

Blue cut lens can effectively filter out high-energy blue light from screens, electronic devices and lighting. This blue light usually comes from electronic devices (such as computers, mobile phones, tablets, etc.) and LED lights. Long-term exposure to these blue lights may have adverse effects on the eyes, such as eye fatigue, blurred vision, dry eye symptoms, decreased sleep quality, etc.

Fast-changing means that these lenses change to a darker color faster than regular photochromic lenses in sunlight, change to a darker color in the same amount of time, and correspondingly fade faster after going from outdoors to indoors.
