Aging comes with a lot of eye-related problems. Bifocals are getting common among the elderly, but a new technology called progressive addition lenses (also known as progressives) is here to replace them. This new technology allows farsighted and short-sighted people to enjoy the advantages of natural vision without making use of dividing lines like in bifocals. Such people can now see distant to near to intermediate vision needs and back again with little or no adjustments and discomforts. In a nutshell, these progressives give several focal points in only one lens.
These progressive lenses are also known as varifocal lenses. It is very frustrating when given two prescriptions for distance vision and reading. Previously, people that face such situations have to buy two bifocal lenses and switch between their use. But with varifocal lenses, this problem is easily resolved. The glasses change strength from top to bottom with several focal points allowing the vision of all distances.
Belson Opticians offer you the best grade of varifocal glasses you can get in the market. We make use of the best supplies of materials to make the best and easy to use varifocal contact lenses. We are a leading lens provider in the UK and are well-known for high-quality and long-lasting varifocal lenses.
What Are Varifocal Glasses?
Varifocals or varifocal glasses are progressive lenses that allow the automatic adjustment of the eye to be able to view both near and far distances easily. To achieve this auto-adjustment that are drawbacks in bifocals, they make use of multiple focal points. This means that a user who used to make use of two bifocal glasses for reading and distant vision needs only one now; a varifocal glasses.

Varifocals are carefully designed not to include the dividing lines that bifocals have. This makes the glasses cosmetically appealing and can also work to hide presbyopia.
How Do Varifocal Lenses Work?
Varifocal lenses make use of auto-adjustment to different distances that are to be viewed by the user. To achieve this properly, there is a change in the strength of the lens from top to bottom. This change is gradual and allows the user of the glasses to see far, near and intermediate objects easily.
The varifocal lens is divided into three major regions:
- The distance region: this is the upper part of a varifocal lens that allows for distant vision.
- The intermediate region: this allows for intermediate distance vision and connects the reading and distance regions.
- Reading region: this lower part of the varifocal lens that provides for reading.
So, to view any distance that is required, all you need to do is to move your eyes to the region that allows the vision of such distance. At Belson Opticians, we use to make use of precise digital eyecare to find the measurements that best suits your needs. This will make it easier for you to quickly switch to the different types of distant vision you desire.
How Long Does It Take To Get To Adjust To Varifocals?
When you buy any pair of glasses, you will need to get used to how it works. Some opticians often say that your eyes and brain need to be in synch to understand how a new pair of lenses work. This is very true, particularly to varifocal lenses.
Initially, it may be uncomfortable, and you might experience dizziness when moving from one viewing region to another. This feeling does not last for long, but the best way to get used to this new type of glasses is to keep wearing it.
Varifocals are a new technology that most people have not tried out before. So, many, it may take a few days or weeks to adjust to the new glasses, and for others, it may take a longer time. Many people complain that they can only see the rim of their varifocals, but this is perfectly normal. The brain must also be allowed the time it needs to adapt to the new visual conditions.
Using the varifocals that we provide in Belson Opticians is less stressful than bifocals. All you need to do is move your eye to the region that allows a type of vision, and the lens will do the work for you. Adjusting to varifocals or varifocal contact lenses should not take more than two weeks.
How To Look Through Varifocals?
One of the differences between varifocals and bifocals is that varifocals do not have a dividing line in their lens. Instead, the lens is divided into three regions for the viewing of different distances. To properly view a particular distance, move your eyes to the region of the glasses that you wish to view and focus on it. Make sure that the lens of your varifocal is big enough to accommodate the comfortable vision from these regions.

Side Effects Of Wearing Varifocal Lenses
People who begin to wear varifocal lenses usually complain of a couple of problems. The glasses themselves are not harmful to the eye when adjusting to the conditions of these glasses a couple of sensations may be experienced.
A common problem that people face with varifocal glasses is the inability to focus when it is required. This problem leads to dizziness, headaches and migraines when performing quick auto-focusing tasks like switching from reading a book to looking at the sky. This problem usually goes away with time as the user adapts to his/her new pair of varifocals.
Another side effect of wearing varifocals is that you may experience a swimming-like feeling when walking. This feeling can be likened to the dizziness one feels when awakening from sleep. If you are too aware of the peripheral distortions in your glasses at the edges of the lens, this sensation will be experienced.

Also, another way to avoid this side effect is to avoid looking at the distortions when walking.
