Single Vision Eyeglass Lenses
“Single vision” eyeglasses are the type of eyeglass lenses where the lens is designed for one specific distance. Single vision commonly refers to ‘distance eyeglasses’ and ‘reading eyeglasses’.
Distance Eyeglass Lenses
Distance eyeglasses are used to help see far away (for driving or watching TV for instance). Some patients with a mild prescription may only use their distance vision eyeglasses occasionally, however many patients require this type of eyeglass lens all the time; and in many cases will leave them on even when they are looking at closer distances such as reading or at a computer.
Reading glasses are used for closer distances such as reading a book, looking at a menu, cell phone, and sometimes a computer. In many cases, the lenses in reading glasses will blur distance vision, so the eyeglasses will need to be removed when looking far away. It is important to note that there is a difference between the magnifying reading glasses that are sold in a pharmacy or grocery store, and reading glasses with a prescription dispensed by an optometrist or eye doctor.
Trifocal Eyeglass Lenses
Trifocal eyeglasses are similar to bifocal eyeglasses however in addition to the top portion for distance and the bottom portion for reading this lens type also has a middle zone that is used for intermediate distances such as computer. The distance, intermediate, and reading zones are each separated by a line.
Progressive addition lenses are sometimes referred to as a “no line bifocal” glasses. Progressive eyeglasses have a graduated change in the lens from distance, to intermediate, to near without any lines in the lenses.
Our Markham optometrists fit all types of eyeglass lenses for children with a special lens type that passes safety standard testing.
