Understanding how varifocal lenses work

If you're over a certain age, you might have noticed that your eyesight isn't quite what it used to be. Suddenly, you find yourself struggling to read small print or making frequent trips to the optician to update your prescription. If you're looking for a solution that's more practical than constantly swapping between different pairs of glasses, then you might want to consider varifocal lenses.

Varifocal lenses, also known as progressive lenses, are a type of lens that provides different prescriptions in different areas of the lens, allowing the wearer to see clearly at multiple distances. They're popular among people who need different levels of magnification for reading, using a computer, or looking into the distance. In this blog post, we'll delve into the details of how varifocal lenses work, their advantages, how to get used to them, and other related topics.

How Do Varifocal Lenses Work?

1. They have a gradual change in prescription

The lens power gradually changes from distance vision at the top to reading vision at the bottom, with intermediate vision in between.

2. They use a technology called “free-form” design

This technology allows for a more customised lens design that takes into account the unique needs of the wearer, resulting in improved vision clarity.

3. Varifocal lenses have multiple zones

The top of the lens is for distance vision, the middle for intermediate in the middle and the bottom for reading vision. Each zone is blended together to make a smooth transition between the prescriptions.

4. The shape of lens determines the width of each zone

The more rounded the lens, the wider the viewing area for each zone. A flatter lens may provide a smaller viewing area for each zone.

5. Wearer need to look at the lower part of the lens when looking at close-up things

This requires the wearer to tilt the head slightly downwards to look through the reading zone.

6. Getting used to varifocals may take some time

It can take a few days to adjust to the new way of seeing. The wearer may experience some distortion or blurriness in the beginning, but this should improve with time. So, this is how varifocal lenses work!

Getting Used To New Varifocals

When you first start wearing varifocal lenses, it can take some time to get used to them. Here are a few tips to help you make the adjustment:

• Start by wearing them for short periods:If you're not used to wearing varifocals, it's best to start by wearing them for short periods of time and gradually increasing the duration as you get used to them.

• Look straight ahead when reading:To see through the lower part of the lens, you'll need to look straight ahead and point your nose at the text you want to read. Avoid looking down through the lens, as this can cause distortion.

• Adjust your head position: When looking at distant objects, you may need to adjust your head position slightly to find the clearest part of the lens.

• Be patient: It can take up to two weeks to fully adjust to new varifocals, so be patient and give yourself time to adapt.

Cost of Varifocals

The cost of varifocal lenses can vary depending on the type of varifocal lenses, the frame you choose, and your location. As a general rule, varifocals are more expensive than single vision lenses, but they're also more versatile.

Specscart provides best-in-class, widest vision field varifocal lenses for just £84, which are usually priced above £200 by other brands.

Can you wear varifocals for driving?

Yes, varifocals can be worn for driving. In fact, many people find that varifocals are well-suited for driving because they allow for a seamless transition between distances. However, it's important to make sure that the lenses are properly adjusted for driving, as the placement of the corrective power can affect depth perception and peripheral vision.

Can new varifocals give you a headache?

It is possible for new varifocals to cause headaches or other discomfort, especially if the prescription is significantly different from your previous glasses. However, this is usually a temporary side effect that should improve as you get used to the new lenses.

If you experience persistent headaches or other discomfort, it's important to speak with your eye doctor. They may be able to adjust the prescription or suggest other solutions to improve your comfort.

What shape glasses are best for varifocals?

The best shape of glasses for varifocals depends on your individual needs and preferences. In general, it's important to choose frames that are compatible with the size and shape of the varifocal lenses.

Some people prefer frames with minimalistic design, such as rimless or semi-rimless frames, as they can provide a wider field of vision without any obstructions. Others may prefer full-rimmed frames, which can provide more stability and durability.

Ultimately, the best frame for varifocal lenses is one that fits comfortably, provides the necessary support for the lenses, and suits your personal style.
