3 Common Problems with Progressive Lenses
Though progressive lenses are popular to correct some eye conditions, there are also some drawbacks. So, in the following section, we will show you some common problems with progressive lenses.
Dizziness: the three different focal lengths of progressive lenses can make people susceptible to dizziness, as well as vertigo. From long to medium to short distance, the lenses offer a gradient of increasing strength. So, it would have trouble in adapting the glasses for the people who are wearing them for the first time. A common mistake is to look out of the wrong focal length, causing their vision to be blurry and lead to an overall feeling of dizziness.
Peripheral distortion: another common problem of progressive lenses is the way in which they blur peripheral vision. Most glasses cause an initial distortion to vision. However, the three different segments found in these lenses can make that distortion feel more prominent than other pairs of eyeglasses. And most people may need two weeks to adjust to progressive lenses.
Depth perception: Since progressive lenses provide three different prescriptions to see objects clearly for different distances, it is important that you need to move your head instead of your eyes when focusing on objects at different distances. Prior to adjusting to this little nuance, progressive lenses can cause depth perception to feel off.
From the above information, you have known some common problems with progressive lenses. So, you may ask how to adjust the progressive lenses. The most popular way is that you need to wear them frequently.
Disadvantages of progressive lenses
Wearing progressive multifocal glasses for the first time may cause slight dizziness and shaking when walking. Be careful when moving up the stairs. The perception of space changes, the perception of the distance of the object, and the perception of depth have changed. New wearers should not drive immediately and do vigorous exercise. When you look close, you need to turn your eyes down, and your eyes are mildly uncomfortable. Seeing the object through the blurred vision area around the lens, the object becomes blurred. Therefore, when new wearers look at things, turn their heads more, turn their eyes less, try to use the far-distance zone, the near-distance zone, and the middle-distance zone to see the object.

How Do Progressive Lenses Work?
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.
