Understanding varifocal glasses

Traditionally, if you needed two pairs of glasses – one pair for close-up work and one pair for everyday wear – you had to switch between them. That meant carrying two pairs of glasses with you everywhere you went.

This got annoying, so the bifocal glasses were invented to allow the user to see objects both far and near. These were then refined to allow wearers to see a wider range of distances in one pair of spectacles. But what are varifocals and how do they work? Read on to learn more about varifocal glasses and their uses in vision correction.

What are varifocal glasses?

Varifocal lenses, also known as progressive lenses, look the same as single vision lenses, but they are actually multifocal lenses that correct vision at different working distances – from reading distance to far distance.

Different types of vision according to different types of lenses.

The distance vision part of the lens is usually in front of the pupil, while the near vision section is located in the lower section of the glasses to allow you to read books, magazines, and menus with ease. They can take some time to get used to but are a valuable tool for those with multiple different prescriptions.

What is the difference between bifocal and varifocal glasses?

Bifocal glasses have two distinct optical powers. The designated spots in the lenses where the prescriptions change is very obvious and there is a distinct line between the areas. Varifocal lenses offer continuous vision across all distances in a single lens, without the obvious lines, and are designed to help correct presbyopia – most common in people over 40.

How do varifocal glasses work?

Varifocal lenses work by changing power from the top to the bottom of the lens. Moving your eyes up and down the lens will give you clear vision at every distance. So, for example you can glance down at your phone when out and about without moving your head too much before looking back up and carrying on down the street.

Reading

The bottom of your varifocals are for close distance reading. There is some soft focus at the edges of your vision in this part of your lens but you will have no difficulty reading up close, doing crafts, and other activities that need near vision.

Intermediate

The middle of the lenses is for intermediate distances.It’s perfect for tasks like using a computer or watching T.V. You might notice some blurred vision at your periphery.

Distance

Distance vision is through the upper part of the lens – no more blurry sunsets or missing out on bird watching. There might be a small amount of soft focus at the edge of your vision. H2 Benefits of Varifocal Glasses

Benefits of varifocal glasses

Although varifocal glasses tend to be more expensive than a single pair of glasses, they save you from having to buy two separate pairs of lenses. Which means you spend less but also don’t have to keep switching between multiple pairs and means you’ll never miss a moment again.

Varifocal lenses can also help with the eye condition presbyopia. This affects many people as they age but varifocals can help with the various symptoms that present.

Who needs varifocal glasses?

Although they’re very useful, varifocal lenses aren’t for everyone. They’re typically only prescribed to people over 40 years-old who need more help focusing on nearby objects. Presbyopia, a normal part of ageing that means the eye’s lens begins to find it harder to focus on close objects. Symptoms include blurred vision, poor vision in darker environments, eye strain and headaches and the condition can be diagnosed at a routine eye check.

Choosing the right varifocal glasses

You have a lot of freedom when it comes to choosing your varifocal glasses depending on your prescription. Some strong prescriptions may be limited to certain frame styles due to lens thickness but, in general, there are plenty of options to suit your needs and style – in fact, there are over 1,000 different types of varifocal glasses on the market. So book a style consultation with one of our friendly opticians to help you find the perfect pair of glasses.


Adjusting to varifocal glasses

It can take a while to adjust to your new varifocals. It can take anywhere between a few days to a few weeks to give your brain time to adjust.

It might feel strange at first but the best way to adapt is to keep wearing your glasses so that your eyes can gradually adjust. Resist the urge to take them off or switch back to your old glasses.

Most people adjust to their new lenses quickly but others may experience slight dizziness when moving quickly from one viewing area to the next. These sensations shouldn’t last long but if you’re concerned or not adjusting after a few weeks, don’t hesitate to get in touch with your optician.

Looking after varifocal glasses

Clean them daily with a microfibre cloth and lens cleaner to keep them free of dust, dirt, and fingerprints. When you’re not wearing your glasses, store them in their case or in a safe place so they don’t get scratched or damaged.

Conclusion

Varifocals are a valuable option for vision correction for those who require multiple prescriptions or who are experiencing issues with presbyopia. They are more convenient than needing two pairs of glasses and can be the more affordable option as well. And with a wide range of frames to choose from, you don’t have to sacrifice style for clear vision.

Migraine glasses: can tinted lenses help with headaches?
If you experience migraines or frequent headaches, you may have noticed that light can make symptoms feel worse. Bright environments, glare or certain patterns can trigger discomfort and make it harder to focus. Many people searching for migraine glasses in the UK are looking for ways to reduce these visual triggers. While glasses cannot treat migraines themselves, certain lenses, including carefully selected tinted lenses, can help improve visual comfort and reduce the impact of light. If you are exploring your options, it can also help to understand how tinted lenses for everyday comfort and clarity and everyday use.   Why light can trigger migraines and headaches For many people, migraines are closely linked to how the brain processes light. Bright or flickering light, glare from screens, or high-contrast environments can place extra strain on the visual system. This can lead to: Increased light sensitivity (photophobia) Eye strain and visual discomfort Difficulty focusing Headaches triggered or worsened by bright environments Some people may also experience visual stress, where patterns or contrast make text or surroundings feel uncomfortable or unstable.   What are migraine glasses? The term migraine glasses is often used to describe glasses designed to reduce light sensitivity and visual discomfort. In many cases, these involve tinted lenses that help soften brightness and reduce the intensity of certain light wavelengths. One commonly referenced option is FL-41 tinted lenses, which use a rose-based tint designed to filter specific parts of the light spectrum. Some people find this type of tint more comfortable, particularly in environments with artificial lighting or screen use. However, there is no single tint that works for everyone, and results can vary.   Do FL-41 lenses work for migraines? FL-41 lenses are often discussed in relation to migraines, and some people report improved comfort when using them. They are designed to reduce certain wavelengths of light that may be linked to visual discomfort. However, it is important to understand that: They do not prevent or treat migraines Their effectiveness varies between individuals They are one of several tinted options, not the only solution For many people, a personalised approach to tinted lenses can be more effective than choosing a single standard tint.   How tinted lenses can help Tinted lenses work by reducing overall brightness and improving how your eyes respond to light and contrast. For some people, this can help: Reduce visual discomfort in bright environments Soften glare from screens and artificial lighting Make reading or focusing feel easier Create a more relaxed visual experience If your symptoms are linked to light sensitivity or visual stress, you may also benefit from understanding the different types of tinted lenses and colours available, as some tones feel more comfortable than others.   Tinted lenses vs blue light glasses You may also come across blue light glasses when searching for migraine solutions. Blue light lenses are designed to filter a portion of light from digital screens and may help reduce glare for some people. However, there is currently limited evidence to show that they reduce migraines or prevent headaches. These lenses can enhance warmer tones, meaning a white background may appear slightly softer or more sepia in tone, similar to the setting often used on e-readers. Tinted lenses tend to offer a broader approach by reducing overall brightness and improving contrast, which may feel more beneficial if your symptoms are linked to light sensitivity rather than screen use alone. Compare blue light lenses vs tinted lenses to understand which is right for your needs.   Finding the right tint for you There is no one-size-fits-all solution when it comes to migraine glasses. The way your eyes respond to light is highly individual. Some people find relief with softer tones such as rose or grey, while others benefit from more specific colours tailored to their visual response. If visual stress is a contributing factor, a personalised assessment such as a colourimetry visual stress test can help identify which tint feels most comfortable for you.   Start with a full eye examination Before choosing tinted lenses or migraine glasses, it is important to understand what is causing your symptoms. A comprehensive eye examination allows us to assess your vision, check for underlying eye conditions, and understand how your eyes respond to light. From there, our qualified dispensing opticians can guide you towards the most appropriate options for your needs.   Takeaway Migraines and headaches can affect everyone differently, and the way your eyes respond to light is highly individual. While glasses cannot treat migraines, the right lenses can help reduce visual triggers such as brightness and glare, making everyday environments feel more comfortable. Tinted lenses, including options similar to FL-41, may help some people by softening light and improving visual comfort, particularly where light sensitivity or visual stress is a factor. However, there is no single solution that works for everyone, which is why a personalised approach is so important. At Leightons, we take the time to understand your symptoms, your lifestyle and how your eyes respond to light. Starting with a comprehensive eye examination by one of our optometrists, our qualified dispensing opticians can advise on the correct lens solution or you, whether that involves tailored tinted lenses or further assessment such as colourimetry.
