The lens material

Lens material affects the effect of protecting our eyes, so we should choose the kind of driving glasses made of polarized lens, which can effectively reduce the dazzling lights, and can filter out the redundant lights. When used at night, the powerful light is softened and the vision is clearer, thus ensuring the safety of drivers and relieving eye fatigue. If you can, let the seller dim the light when you buy, feel the softness and clarity of the light after wearing the product.


Progressive lenses and single vision lenses

Single vision lenses are the most commonly used prescription lenses. This lens type has a single field of view or a prescription ability of the entire lens and can be used to correct myopia (nearsightedness) or hyperopia (supervision).

Progressive multifocal lenses are lenses with different upper and lower powers for the upper part to see far, and the lower part to see near. The distance from the fixed power above the lens to the fixed power below the lens does not change suddenly, but there is a gradual transition between the two through the gradual change in refractive power.

High-index lenses correct all types of refractive errors. And they are also available as single vision lenses, or a reading prescription that corrects presbyopia, such as in a bifocal or progressive lens.
