What is the difference between single vision lenses and multifocal lenses?

You may have heard of them: single, multifocal and varifocal lenses. But what does this actually mean and what type of lenses is best for you or your employees? In this article, we explain the difference and provide tips on choosing the right lenses for optimal work performance and comfort.

What are single lenses?

Single-lens glasses correct your vision at one specific distance: near or far.

• close: Single close-range glasses have a plus strength. This type is ideal for reading books or working at a short distance.
• Far away: Single distance glasses have a minus strength, suitable for tasks such as driving or watching TV.

With single lenses, the strength is the same everywhere in the glass, so you can only see clearly from one distance.

What are multifocal lenses (also known as varifocal lenses)?

Multifocal lenses, also known as varifocal lenses, combine multiple strengths in one lens. This means that with one pair of glasses, you can see clearly both near, at a distance (for computer work, for example) and far. The strength changes gradually depending on where you look in the glass:

• Reading distance: If you look down, you can read without problems.
• Intermediate distance: If you look slightly higher, this is ideal for computer work or other medium-distance tasks.
• Far away: If you look straight ahead, you can see clearly at a long distance.

Multifocal lenses are a solution for anyone who needs correction for different distances, without having to constantly change glasses.

When do you choose progressive or single vision lenses?

After 40, many people experience long-sightedness (presbyopia), which means that your eyes have trouble focusing at close range. At that moment, multifocal glasses can be a practical solution, because these lenses make it possible to see clearly at different distances without changing. For people who only need a correction for far or near distance, single glasses are sufficient.

Multifocal lenses and the workplace

For employees who often switch between different viewing distances, such as reading, computer work and meetings, progressive lenses are a worthwhile investment. At Seeh, we understand how important good vision is for work comfort and productivity. Through our collaboration with Hans Anders, we offer customized solutions for employees so that they can work with a clear view and optimal comfort. We do this with monitor glasses.

Whether you need single or multifocal (varifocal) lenses, good vision is essential, both at work and at home. Especially in the workplace, the right glasses make a big difference in comfort and productivity. Still unsure about the right type of glasses?

Frequently asked questions about single and multifocal lenses

When do I need progressive lenses?
If you notice that you need a correction for both near and far, progressive lenses are a handy solution. This usually becomes noticeable around the age of forty.

What is the difference between varifocal lenses and multifocal lenses?
Varifocal lenses and multifocal lenses are two terms for the same type of glass. Both offer different strengths in one lens, allowing you to see clearly at multiple distances.

Are progressive lenses suitable for screen work?
In principle, yes, because multifocal lenses have an interval that makes it possible to work on a screen. However, there are better options, such as workforce glasses (also known as work glasses or computer glasses). Workforce lenses are specifically designed for intensive computing and offer a wider, more comfortable field of view at short and medium distances. This means you look at the screen less tired, which significantly improves productivity and viewing comfort. Always get advice from a specialist to find the best solution for your workplace.
