1.56 Photochromic Blue Block Flat Top Bifocal Lens

Product Details

Product Features

A bifocal lens is specially designed to correct vision problems and meet the needs of different distance vision. It features two different lens powers in one lens. The upper half of the bifocal lens is for distance vision, while the lower half of the lens contains a small segment for correcting near vision. This design divides the lens into two main areas. Due to the imaging principle of the lens, even half a lens can still present a complete image, and the two images do not interfere with each other. 

Product Advantages

Bifocal lenses have significant advantages in vision correction. For wearers who need to correct both hyperopia and myopia, bifocal lenses can achieve two different diopter adjustments on the same lens.

Flat-top lenses are considered one of the easiest multifocal lenses to adapt to, making them the most commonly used bifocal lenses. This style of lens is also among the most readily available, suitable for almost all types of moderate lenses, including comfort lenses. Flat-top bifocal lenses take advantage of the full width of the lens, providing users with a clear transition between reading and distance vision.

Photochromic bifocal lenses will automatically darken when outdoors, effectively blocking UV damage and reducing the risk of sun exposure, thereby reducing the possibility of eye diseases such as cataracts and macular degeneration. Photochromic glasses can also automatically adjust the color according to the intensity of light, eliminating the trouble of carrying and changing ordinary glasses and sunglasses. In strong light, photochromic glasses can reduce the intensity of light, making the eyes more comfortable and reducing the degree of eye fatigue.
