Single vision lenses are for standard glasses prescription. These lenses have only one vision area in the entire lens, and the correction area can be long-distance, medium-distance, or reading.
Long distance-If you wear glasses all day, but don’t need bifocal/zoom, or you mainly need these glasses to see far things.
Middle distance-If you mainly need these glasses to work with computers or other things at arm distance, or you are a musician, you need these glasses to read music.
Reading-if you need to read things close to you.

A bifocal lens refers to a lens with two focal points. A small part of the eyepiece lens is reserved for near vision correction. The rest of the lens is usually distance corrected. When focusing on a far point, you look up and pass through the distance part of the lens; when focusing on reading material or detailed work beyond 18 inches, you look down and pass through the dual focus part of the lens.

Progressive lenses are closest to the natural vision of a pair of prescription glasses. They are not just close corrections defined in one lens. On the contrary, progressives provide a smooth transition from distance, through the middle to near, and all corrections are included. This escalating prescription means that you can look up into the distance, look forward to the computer in the middle area, look down, and comfortably read close and do fine work.

Blue light blocking glasses are ideal for all glasses wearers, especially office workers and those who use digital devices for long periods of time. Helps protect your eyes from harmful blue light and reduces eye strain.

When you go out, the lens will automatically darken due to the sun’s ultraviolet rays! Same quality as your doctor’s office.
