1.61 Blue Block Progressive Finished Lens

● It allows for a seamless transition between different prescription powers within a single lens. The upper part of the lens is typically optimized for distance vision, enabling clear sight when looking at objects far away. The middle portion provides an intermediate power, which is useful for tasks like looking at a computer screen or reading street signs from a medium distance. The lower part of the lens is designed for near-vision activities, such as reading books, newspapers, or using a mobile phone. This eliminates the need to switch between different pairs of glasses for various visual tasks, providing convenience and a more natural visual experience.

● With a refractive index of 1.61, these lenses are relatively thin and lightweight compared to lenses with lower refractive indices, such as 1.50 or 1.56. The high refractive index allows the lens to bend light more efficiently, meaning that the same corrective power can be achieved with a thinner lens. Thinner lenses are less likely to cause pressure on the nose and ears, reducing the discomfort associated with wearing glasses for long periods. 

● Convenient and offers a younger appearance.

● Blue block harmful blue light.
