Common Problems with Varifocal Glasses
In this section, we will list some common problems with varifocal glasses. The most common problem with varifocal glasses is people being unable to focus on what they need to. Losing focus often leads to some discomforts such as headaches or dizziness when performing tasks that require quick changes in near and middle-distance focus.
Besides, some people also experience a sort of swimming feeling when they are walking. It may be caused by being very aware of the distortions in your peripheral vision as well as the reading portion at the lower part of the lenses.
So, how to use varifocal glasses? The best way is to keep yourself from looking downward as you walk. You may also experience soft focus at the edges of the lenses and need to move your head more to see near objects better.
Can clear lenses be polarized?
At present, there are no clear polarized lenses. A polarized lens is a thin film vertically arranged with silicon crystal coating placed inside the lens, just like a shutter, which covers the parallel light and only allows the vertical light to pass through. In this way, the glare from all directions can be eliminated, so it is clear and comfortable to wear. Transparent polyamide, the material of nylon lens, is a new variety of polyamide. The material of the nylon lens is mainly transparent polyamide. Due to the effect of the light filter, only light from a specific direction is allowed to pass through the lens, which filters the dazzling light from the sun on the water, land, or snow very well. It can not only make the landscape soft, clear, and natural but protect the eyes to a certain extent.
How To Use Contact Lens Correctly?
A periodic review is necessary. In the process of wearing contact lenses, the eyes may change due to the existence of contact lenses. At the same time, in the process of wearing contact lenses, the lens may be polluted, damaged, and have other changes. This is to check regularly to prevent damage to the eyes. Usually, the recommended review period is one week, one month, three months, half a year, and once every half a year after wearing it.

What Are Bifocal Glasses?
Bifocal lenses are divided into two parts to accommodate two different prescriptions in one lens. One area of the lens will have one prescription (usually distance) and a segment in the lower half will have the other (usually near vision).
Bifocal glasses are most used to correct presbyopia - an age-related eye condition where the eyes begin to struggle to focus on anything up close. This difficulty usually results in people requiring glasses with two different prescriptions, one for short and one for long-distance.
On bifocal glasses, there is a distinct line between the different prescriptions. Wearers have to look up and down to switch between the prescriptions they need, with long-distance prescriptions at the top and near vision at the bottom.
The main parts of glasses
1. Spectacle lenses
One of the most important accessories for glasses is spectacle lenses. Due to the increase in myopia patients, the demand for spectacle lenses is also very large, but the prices of spectacles on the market are also uneven. To know whether the spectacle lens is good or not, you can't just look at the price of the product, but learn more about the value of the lens itself. For example, the resin lens is lighter and suitable for patients who wear it for a long time. The quality of the optical glass lens is better, and it is not easy to break, suitable for some elderly people.
The quality of spectacle lenses is also a key consideration. The market generally classifies lenses based on their structure, materials, and usefulness. The information on spectacle lenses is mostly chemical substances. It is very beneficial for us to select some good-quality lens materials. It is not only necessary to consider the function of the lens, but also to consider whether the lens material is harmful to the human body. Generally, the crystal stone materials are very safe and reliable, and we can choose carefully.
2. Spectacle frame
Another important figure in eyeglasses accessories is the frame. For those who like lightweight glasses, it is more appropriate to choose ultra-light frames or half frames. However, the frame must have durable and play a good role in maintaining the lens, otherwise, it will lose the meaning of the frame. Of course, the temples are also a part of the frame. There are also nose pads for glasses accessories. Many people have more requirements for nose pads. Generally, they choose soft ones that are not easy to press on the bridge of the nose.
