Types of Lenses in Glasses | Aphrodite Livanes Optometrists

Whether you’re buying your first pair of specs or upgrading an old prescription, choosing the right lenses is even more important than picking the perfect glasses frames.

With so many lens options available today, it’s easy to feel overwhelmed – but we’re here to help you make the choice that’s right for you!

So, if you’re contemplating single vision vs multifocal vs blended lenses but are confused about the differences – read on.

Why is it so important to choose the right lenses?

Choosing the right lenses isn’t one-size-fits-all – your specific vision needs play a vital role. For example, someone struggling to see things up close due to age-related changes (known as presbyopia) may benefit from lenses that offer multiple focus zones.

In contrast, if your vision is blurry only at a distance or up close, a single-vision lens might be all you need.

Research has found that the right type of lenses in glasses has a positive impact not only a person’s vision, but also their quality of life (1).

Understanding the Different Types of Lenses

Single Vision Lenses

Single vision lenses are for people who need correction for just one field of vision – whether it’s distance (eg driving), near (eg reading), or intermediate (eg computer work). They’re commonly prescribed for myopia (short-sightedness), hyperopia (long-sightedness), or presbyopia (age-related near vision loss).

Patients with astigmatism (irregularly shaped cornea which reduces the eye’s ability to focus light) may also benefit from single-vision glasses – generally fitted with cylindrical or spherocylindrical lenses, which disperse light in one direction and help correct the blurry vision.

Single vision spectacles are often considered a simple, affordable option that is easy to get used to. However, as they only correct one vision range, you may need multiple pairs.

Bifocal Lenses

Bifocals are the original multitaskers! These are often prescribed for people who need help with both distance and near vision, especially those over 40 experiencing presbyopia.

Bifocal lenses are divided into two segments:

The upper portion corrects distance vision
The lower portion corrects near vision

While bifocals can be a handy two-in-one solution, you can generally see a visible line between the two segments, which can take some getting used to. Some wearers also report finding the jump between zones a bit abrupt.

Trifocal Lenses

Similar to bifocals in design and function, trifocals are designed for people who need correction at three distinct distances – near, intermediate, and far. They’re often used by those with advanced presbyopia, offering clear vision at all ranges without switching glasses. There are however visible segment lines to adjust to.

Multifocal Lenses

If you’re after something a little more seamless, multifocals may be a good option. These lenses allow you to see clearly at multiple distances – near, intermediate, and far – without needing to switch between glasses.

There are a variety of different types of multifocal lenses, including:

Progressive lenses: Offer a smooth, gradual transition between distance, intermediate, and near vision – without the visible divide and sudden adjustment of bifocals.
Blended bifocals: Similar in function to standard bifocals, but with a more aesthetically pleasing look. The line is softened or hidden, making them less noticeable on your face.
Extended focus lenses: Designed for clear close-up and intermediate vision with a seamless, wider viewing zone – ideal for multitasking in office or home settings.
Office or computer lenses: Similar to extended focus lenses but specially designed for computer workers or those required to stare at screens all day.

Tips for Choosing the Right Types of Lenses for your Glasses

Have an eye test with an experienced optometrist to ensure you have the correct prescription.
Discuss your habits and challenges with your optometrist – they’ll be able to recommend the best lens type for you.
Consider your lifestyle and workplace environments and needs, including how many hours a day you spend on screens. If you play sports, you may want lenses with enhanced impact resistance.
Your prescription strength may influence your choice of lens material: higher prescriptions may benefit from high-index lenses to reduce thickness.
And, revisit your prescription regularly – your vision can change more often than you think!
