Many people have heard the progressive lenses. But do you know what they are and how progressive lenses work? If not, keep on your reading and you will find some useful information here.
What Are Progressive Lenses?
Progressive lenses are designed for people who are over 40 years old. It is a blended multi-focal lens with distance correction at the top, intermediate in the middle, and reading at the bottom. The goal is for the lens to work how your eye naturally works to let you see things both close up and far away.
Progressive lenses are made with an hourglass shape so there is some blurriness on the outer edges, but since it gives you your full range of vision, it is generally better than a bifocal despite being similar.
After learning what progressive lenses are, do you know how to use progressive lenses or how progressive lenses work?
How Do Progressive Lenses Work?
In this section, we will show you how progressive lenses work. With digital progressive lens, there are dozens of incremental prescriptions between the distance and reading sections. You have to point your nose at what you are looking at. However, it is difficult for some people to get used to the progressive lenses and it may take some time to adapt to them. You can read the post: How long should it take to get used to progressive lenses to learn more.
Because progressive lenses work like how your eyes do, many people prefer them over bifocals. They also have more lens options such as colors and materials than bifocals, so they are becoming more popular.
So, how do progressive glasses work? Progressive lenses allow you to see at all distances with one pair of glasses. They start with your distance prescriptions at the top of the lens and increase as you move toward the bottom of the lens. You can move your head position to allow you to focus through different areas of the lens.
Move your head upwards to see something in the distance, and hold it straight for intermediate or arm’s length vision and down for near vision for objects that are close up. Apart from the aesthetic improvement of the lens without the line segments, progressive lenses avoid the visual discontinuity or image-jump when your eyes shift from one zone to the other in non-progressive multifocals.
