Are you tired of carrying around multiple pairs of glasses for different distances? Varifocal lenses, also known as progressive lenses, offer a convenient solution. These lenses allow for continuous vision at any distance, all within a single lens. Not only do they provide seamless correction for presbyopia, but they also eliminate the telltale lines found in traditional multifocal lenses. In this article, we will delve into the workings of varifocal lenses, discuss their pros and cons, and provide tips for finding the best ones for your needs.

How do varifocal lenses work?

Varifocal lenses are designed with multiple prescription strengths to cater to different distances - distance, intermediate, and close reading. Manufacturers achieve this by altering the thickness of the front and back of the lenses, creating a vertically smooth range of corrected vision. These lenses are particularly beneficial for individuals who require simultaneous correction for distance and close-up vision.

There are two main types of varifocal lenses: those designed for everyday use and those tailored for occupational use. Everyday varifocals have a denser focal graduation to handle various distances, such as reading a book, working on a computer, or watching TV. Occupational varifocals, on the other hand, provide more precise vision correction in a consistent office environment.

The pros and cons of varifocal lenses

Main pros:

  1. No visible lines: Varifocal lenses offer a more aesthetically pleasing option compared to traditional bifocals, as they do not have visible divisions. The upper part of the lens is for looking at far objects, the middle and sides are for intermediate distances, and the bottom part is for close-up tasks.

  2. Custom-fit: Eye companies can tailor-make varifocal lenses to suit individual needs. They consider factors like prescription details and pupillary distance (PD) to ensure a comfortable fit.

  3. No need for multiple glasses: Carrying around only one pair of glasses is more convenient and practical for everyday use.

Main cons:

  1. Costly: Varifocal lenses incorporate advanced technology, making them more expensive than standard prescription glasses. It is crucial to invest in high-quality lenses to ensure optimal performance and longevity.

  2. Peripheral vision: Some varifocals may have limited field of view, particularly in the peripheral areas of the lenses.

  3. Adjustment period: It takes time for users to adapt to using prescription glasses, especially varifocals. It may require two to three weeks or longer to fully acclimate to these lenses.

How to find the best varifocal lenses

Finding the right varifocal lenses involves considering various factors. Here are some tips to help you make an informed choice:

  1. Determine your lifestyle needs: Varifocal lenses are designed for different purposes, such as everyday use or occupational use. Choose lenses that align with your lifestyle and visual requirements.

  2. Test the lenses' accuracy: Given the higher cost of varifocal lenses, it is essential to ensure their accuracy before making a purchase. This step will help you avoid any potential issues or dissatisfaction.

  3. Assess peripheral vision: Pay attention to the lenses' design and confirm that they do not obstruct your peripheral vision, as this is a common concern with varifocal lenses.

  4. Consider UV protection: Look for varifocal lenses that offer protection against harmful UV rays. UV exposure can lead to various eye conditions, including macular degeneration and cataracts.

  5. Choose durable lenses: Opt for varifocal lenses that are scratch-resistant, waterproof, and anti-static. These features ensure longevity and maximize your investment.
