Single Vision Lenses

Single vision lenses are standard prescriptions for glasses. The glasses have only one viewing area on the entire lens, and the correction area can be used for long distances, medium distances, or reading. For long-distance, if you wear glasses all day but don't have dual/zoom glasses, or need them most of the time to see things far away. For middle distance, if you primarily need this pair of glasses to work on a computer or something else at arm's length or if you are a musician you need this pair of glasses to read music. For reading, if you need to read things around you, such as files, documents, etc.

Progressive Lenses

Progressive lenses provide a smooth transition from the distance through intermediate to near, with all the in-between corrections included as well. You can look up to see anything in the distance, look ahead to view your computer in the intermediate zone and drop your gaze downward to read, and do fine work comfortably in the close zone. That is to say, progressive lenses are the closest to how natural vision is that you can get in a pair of prescription eyeglasses.

Our Lenses – KR Resin

Impact Resistant

KR resin material has high surface finish, and its products have good flexibility. The coating film can be coated with one layer or multiple layers. The coating material is usually magnesium fluoride (MgF2), and its refractive index is 1.38. This film has considerable hardness. Compared with the linear molecular structure of ordinary lenses, KR super-tough material has a network-shaped cross-linked molecular structure with strong impact resistance.

Improved Clarity

KR resin lens uses the mechanism of destructive interference to reduce the reflected light, and the visible light transmittance is greatly improved, generally reaching 98%. KR super-tough resin lenses have an Abbe number as high as 43, which is a medium-low dispersion material. These lenses minimize the colored edges when viewing objects, resulting in clearer views and the wider vision fields.
