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.

Optical lenses fall into 3 main categories.

Single Vision Lenses, Multifocal Lenses and Occupational or Office Lenses.

All of them are available in different lens materials (effecting lens thickness and impact resistance), can be made as clear, photochromic or sunglasses, and also available with different lens coatings (for durability, eye health protection and enhanced visual performance through glare reduction).

Single Vision Lenses correct sight either in close or in distance viewing.

Multifocal Lenses describe a collective group of lenses correcting two or more viewing distances. Bi-Focal lenses are lenses divided into two parts to correct any two prescriptions, most commonly close and long distance, but sometimes close and intermediate vision for reading and computer work only. These prescriptions are divided by a visible segment on the lens. Tri-Focal lenses work the same way, but correcting vision in three different distances with a small portion of intermediate segment added to the lens too. A more advanced and aesthetically pleasing multifocal lens design, also known as progressive design, has the ability not only to correct vision close and far away, but everything in between. These lenses are developed to shift the power across the lens without visible lines separating the zones or sudden change in power. Although the Bi-Focal and Tri-Focal lenses have their advantages, they are considered outdated and less and less popular, and the expression Multifocal Lenses is now often used as a synonym for Progressive Lenses.

Occupational Lenses (or Office Lenses) are very similar to Progressive Lenses, they have a graduated power over the surface of the lens, without visible segmentation. These lenses are designed to prove the wearer with a large field of view for reading and as the person looks up through the lens the power gradually decreases to accommodate viewing computer screens or looking above to see a presentation during a meeting. These lenses are not designed for clear far distance vision but allows the user to comfortably focus on close up work and glance up across the office or room. These lenses are more useful in relieving fatigue than Single Vision glasses, since they have a range of working distances, and they also provide much wider reading and intermediate area than Progressive Lenses.
