Single vision is the most common type of prescription lenses. This lens type features a single field of vision, or one prescription power throughout the entire lens, for correcting nearsightedness or farsightedness.
With the technological advance of today, there are multiple lens solutions for each condition. Someone who needs glasses to see the board in school or the road signs while driving, can choose not only a single vision lens to correct their distance viewing, but also a progressive lens to shift the power off at the bottom of the lens, where correcting power isn’t necessary to read or write in the textbook, or to look at the speedometer on the dashboard. This relieves the eyes from fatigue and strain. Someone who needs glasses for reading but spends most of the day in an environment where shifting focus between close and distant objects are necessary, progressive lenses can provide a convenient solution, instead of having to take the glasses on and off all day. Nowadays there are special lenses created for office solutions, so we don’t have to compromise a part of the lens for long distance correction, providing maximum field of view for the classroom or office environment.
One of the Optical Dispensers’ critical roles – working together with the Optometrist – is to find out your individual needs and offer you the best solution.
