Choose a quality progressive lens.
Superior progressive lenses provide a better viewing experience. They also remove any distortions you might feel when reading what's in front of you. Lenses can also be coated with special coatings. Anti-reflective coating can prevent glare on the road, and anti-scratch coating can reduce wear marks.
What is a progressive lens?
Progressive multifocal lenses are lenses with different upper and lower powers for seeing far above and below for seeing near. The distance from the fixed far power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power. Compared with ordinary lenses, there are many advantages. The appearance of the lens is like a single vision lens, and the dividing line of the power change is not visible. Not only is the appearance beautiful, but more importantly, it protects the age privacy of the wearer, and there is no need to worry about revealing the age secret due to wearing glasses.
Since the change of the lens power is gradual, there will be no image jump. It is comfortable to wear and easy to adapt. So it is easy to be accepted. Because the degree is gradual, the replacement of the adjustment effect is gradually increased according to the shortening of the short distance. There is no adjustment fluctuation, and it is not easy to cause visual fatigue. Clear vision can be obtained at all distances in the visual range.
Such a pair of glasses meets the use of long-distance, near-use and various distances in the middle at the same time. It is especially good news for teachers, doctors, music workers, and computer operators, because these people not only need to see far and near objects clearly, but most of the time they also need to be able to see middle distance objects such as blackboards, piano scores, and computer screens. . This is not possible with any lens other than progressive lenses.
Single Vision vs Progressive: What Are Their Differences
In this part, we will show you some differences between single vision and progressive lenses. They differ in several factors, so here we will compare them one by one.
Progressive lenses generally have their reading zones just in the lower half of the lenses, while single vision glasses have the reading power all over the lens. So if you are working on something above your head and you need to see some small details, the progressive lenses will not work. And you can not see through the reading zone in progressive you need to switch to single vision reading glasses.
Single vision glasses are cheap than progressive lenses. Compared to progressive glasses, single vision glasses hold way fewer distortions in the periphery. So, there is no need to customize the lens design to the max. In addition, single vision glasses are often available in the optical store while the progressive often needs to be produced for you. In other words, the delivery time of single vision lenses will be shorter for you.
You can use your progressive glasses optimally just in an upright posture. As soon as you lay down on your couch, this will lead to blurry vision. The reason is your changed position which forces you to look lower through the lenses on the screen. However, with single vision glasses, you can change to an upright position and it would not be a problem anymore. You can position yourself on your couch as comfortably as you want and you can still see clearly with your single vision distance glasses.

How to Adjust Glasses If They Pinch Your Nose
In some cases, glasses will pinch your nose, so you also need to adjust them, too. If the glasses frames are metal, you should simply widen the plastic nose pads using your thumbs until the frames fit comfortably. If the glasses frames are plastic, you should soak the arms of your glasses in warm water for 30-60 seconds, and gently apply upward and outward pressure on the end of the arms to get a more relaxed fit.
After that, your glasses will become more suitable.
Unfortunately, not all glasses can be adjusted by yourself at home. You can’t adjust some glasses which are based on the material of your glasses. For example, the glasses with the following material can’t be adjusted at home:
1. Aluminum alloy.
2. Memory plastic.
3. Titanium or memory titanium.
If your glasses are made of these materials, you can’t adjust them by yourself at home. If something goes worse, you need to buy a new pair of glasses. It is also risky to adjust the rimless or semi-rimless glasses by yourself at home.
