An In-depth Look Into Progressive Lenses And How They Work
Updated: Nov 17, 2022
With technology advancing as it is, the traditional way of doing things has become increasingly obsolete. Instead, we’ve had to evolve to take on new tasks and overcome modern-day challenges. This is becoming more apparent with the prevalence of computers and other digital devices in our lives. The need for comfortable and clear near vision is now more undeniable than ever.
Today, people have multiple ways to achieve their desired clear eyesight through ingenuity and fast-paced technological advancements. Premium Progressive lenses have emerged as one such increasingly popular method of doing so. Read on for a comprehensive run-down on what progressive lenses actually are and how to use them.
What are progressive lenses?
Progressive lenses are a form of multifocal lens that can aid people who require corrective lenses to look at objects both far away and close. These lenses are utilised explicitly for clear vision and multiple distances without using a bifocal line.
The older an individual gets, the more likely they are to require progressive lenses. Many have difficulty seeing objects nearby clearly by age 40 – a condition known as presbyopia. To fix this issue, people resort to single-vision glasses for looking at objects at a distance, as well as reading glasses for near vision.
While this is a perfectly feasible – if tedious – approach, progressive lenses provide a more straightforward answer to these vision troubles.
How do progressive lenses work?
Unlike regular bifocals or trifocal lenses, Progressive lenses do not have a visible line that bisects the lens. Instead, they offer a gradual and smooth change in power as you move down the lens. There are no distinctive zones for the different distances. Progressive lenses provide a seamless transition of focal powers that offers clear vision when looking at objects both near and far.
Progressive lenses begin with an individual’s distance prescription on the top of their lens before gradually increasing as it moves towards the bottom. All you have to do is shift your head to focus on the different parts of the lens.
If you want to look into the distance, just look straight. Tilt your eyes slightly lower (~15 Degrees lower) to view things at arm’s length and down to look at objects close to you.
Other than simply looking better, the absence of line segments on the lens helps prevent image jump and visual discontinuity, especially when your vision moves from one area of the lens to another.
Despite the fact that these lenses are most commonplace among older adults, progressive lenses can also be utilized by people outside this age group. For instance, both near and far-sighted children can use progressive lenses as a form of myopia control.
Adjusting to progressive lenses
Although most people tend to adapt to progressive lenses quite rapidly, even immediately—for some people, it might take some days to gain comfortable vision through progressive lenses. This is natural since your eyes must get used to looking through the correct zone of the lens, and the visual changes when you move from one zone to another, particularly if you tilt your head abruptly. Talk to your optometrist if you see that after a few days, you are still having issues adjusting to the lenses; they might not be the best solution or the correct fit for you.
Progressive lenses are the modern-day answer to many of your eye-related needs. They’re convenient, effective, and appropriate for people who require a more complex solution to their vision troubles.
