Varifocal glasses, also known as progressive lenses (PALs), are a marvel of modern optometry. These highly advanced digital glasses offer near, distance, and intermediate vision through a single lens, and come with an incredibly seamless look. Thus, the wearer can see at all distances and focus on multiple points through just one lens.
Varifocal lenses are meant for people with double prescription requirements. Unlike traditional bifocals, varifocals do not have a reading segment or dividing lines, which make them aesthetically more people. Varifocals are perfect for individuals who want to disguise their presbyopia.
Do You Need Varifocal Glasses?
When it comes to who needs what type of glasses, there is no one-size-fits-all. Many people suffer from vision problems since birth. Thus, even children and teens might need varifocals. However, when we talk about typical circumstances, the need for varifocal glasses usually begins after a person touches their 40s.
As you age, the crystalline lens in your eyes loses elasticity and gets stiffer, leading to a deterioration of near vision. The flexibility of the lens in the eyes enables you to focus on different distances. Together with weaker muscles around the eyes, the vision may begin to blur when looking at closeby objects. The condition is known as presbyopia and is a refractive error.
Individuals with presbyopia are the primary target population of varifocal glasses. These state-of-the-art vision-correcting devices enable you to see clearly at all distances.
Things to Know before Opting for Varifocals
Opting for varifocals is a big decision for many people. Therefore, it is important to keep some points in mind. What are they? Let us find out!
- Customisation
Everyone’s vision is different, and no two people’s presbyopia is alike. Therefore, it is important that the varifocal lenses you get are customised to meet your unique vision correction needs.
A ready-made pair of lenses are not the best option when it comes to varifocals. Nowadays, it is even possible to tailor your varifocal glasses according to your lifestyle and behavioural needs.
- Lenses before Frames
When it comes to buying varifocals, you should prioritise lenses and then frames. You should ensure that you have the right lenses first and then move toward frames. For instance, some varifocal frames are more suited for thinner frames, whereas some are meant for thicker frames.
- Lens Enhancements
Last but not least, you must consider lens enhancements while choosing varifocal lenses. Many people are unaware that varifocal lenses also come with additional enhancements, such as anti-UV, scratch resistance, anti-glare, and more. For instance, lens coatings can reduce glare and reflections, and provide clear visual acuity.
Final Words
So, there we have it, a crisp overview of who needs varifocals and the things to consider before buying varifocals. In all honesty, varifocals are a boon for people with presbyopia, and other visual ailments.
So, if you have both near and distance prescription needs, then varifocal glasses are something worth considering. With a seamless look and multiple gradients, varifocals truly stand out as a technological marvel.
