Which type of lenses are made to guard against harmful UV rays?

UV protective lenses are specifically designed to block or absorb ultraviolet (UV) radiation from the sun. UV rays can cause significant damage to the eyes over time, leading to various health issues, including cataracts and macular degeneration. These lenses incorporate UV filtering materials during their manufacturing process to provide a protective barrier against these harmful rays, thus promoting overall eye health.

While polarized lenses (often used in sunglasses to reduce glare) can also provide some UV protection, their primary function is not specifically to guard against UV rays. Similarly, single vision lenses are designed to correct vision without necessarily offering UV protection. Image displacement lenses, while relevant in specific optical applications, do not pertain to UV protection. Therefore, the most accurate choice for lenses that specifically guard against harmful UV rays is UV protective lenses.
