Replace the nose pad on your glasses

Remove the screws clockwise and use a toothpick to remove the things left of the broken pads so that the new one can be installed. The next step is to fix the nose pad that we just removed from it. Hold the glasses and then the hole for the nose pad is up, then place the nose pad in and press it with your finger. Then you can see that the round hole in the nose pad overlays with the round hole in that part, and at this time, you can turn the screws. When you finally turn it, you usually turn it three times to hold the nose rest in place. Often, the nose pad can be swung back and forth after installation. This is to match the different shapes of our noses.

Disadvantages of Progressive Lens

There are deformation areas under the left and right sides of the lens, which make the image blurry and irregular. It takes 1-3 weeks to get used to it. In addition, it has a narrower field of view in the near and middle distances, and long-term concentration on the narrow focal point can easily make the eyes tired. Suitable for people who need to alternate between distant, medium, and near vision.

However, with the development of science and technology, more and more progressive multifocal glasses have emerged that have a wider field of view, more comfortable wearing, and better meet the needs of eyes. Nowadays, the use rate of progressive lenses among middle-aged and elderly people abroad is quite high. Single-lens and double-lens reading glasses are gradually being replaced by progressive multifocal glasses.


Bifocal Lens

Bifocal lenses have two observation areas separated by visible lines, a larger observation distance area, and a smaller reading area. It may take some time for people who are wearing bifocal glasses for the first time to get used to the lenses. This is mainly due to learning how to move the eyes between the observation distance area and the reading area. Some people will also find that there will be an 'image jump' phenomenon at the visible line between the distance and the reading area, especially for those with limited mobility, who must look down when walking. The best way to get used to bifocals is to wear them as much as possible.



What is a progressive lens?

A progressive lens is a lens whose upper sides are used to see far, and the lower side is used to see near. The distance from the fixed distance 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.

Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses. However, is progressive lens good for eyes?


Defects of Adolescent Progressive Lenses

Long-term use of progressive lenses will cause a deficiency of binocular physiological regulation in adolescents. Long-term use of progressive lens may lead to ocular muscle imbalance in both eyes of adolescents. After wearing a progressive lens, part of the field of vision is not clear, which will affect the activities of young people. After wearing the progressive lens, when walking downstairs, riding a bicycle, and doing various sports, you need to see through the near area under the lens to see far, which will affect your activities due to blurring. It is not comfortable to wear a progressive lens to look at an upright screen such as a computer, and the refractive power of a progressive lens in these parts is different. To see the screen clearly, it is necessary to adjust repeatedly, which is easy to cause adjustment disorders and visual fatigue, even dizziness, and eye pain.
