Benefits of glasses without nose pads
Glasses without nose pads are mostly used for sheet materials because the sheet material is lighter and not allergic. From the viewpoint of aesthetics and comfort, no nose pads are more suitable. Glasses without nose pads have a relatively small contact area with the bridge of the nose, so it is not easy to have obvious indentations on the bridge of the nose, while glasses with nose pads will have obvious indentations after wearing them for a long time.
In addition to supporting the frame, the nose pad has another function to prevent allergies and avoid discomfort caused by allergies to metals or other materials. Whether it is better to have glasses with nose pads or without nose pads, depends on your personal situation. If your nose is sensitive to weight or the bridge of your nose is lower, you should choose glasses with nose pads. If you are particularly looking for beauty and don't want any marks on your face, then choose glasses without nose pads.
In fact, it is hard to say which one is better between nose pads and no nose pads. The key is to look at personal preference and wearing comfort. Generally speaking, a high nose bridge is suitable for choosing frames without nose pads. It is more suitable to choose the frames with nose pads for people with flat nose bridges in order to prevent the glasses from sliding off and affecting the visual effect.
It is more reasonable to use a visor
According to experts, if using the sun visor above the seat can solve the problem of dazzling sunlight, it is generally not recommended to use sunglasses. Although high-quality sunglasses can effectively reduce the impact of light on human eyes, they will more or less affect vision. Driving as a high-risk behavior, misjudgment of the environment can easily lead to accidents. If you really want to use sunglasses while driving, it is recommended that you develop a habit of wearing sunglasses to walk or work during your daily. Also, you can choose dedicated driving sunglasses. What needs to be reminded is that if your sunglasses are not usually worn, don't use them alone in the car.
Discoloration time and fading time for color-changing lenses
In general, color-changing lenses take about 30 seconds to 1 minute to darken on average when exposed to sunlight/UV and will continue to darken for about 10 minutes to reach the lens depth of full-color sunglasses. Color-changing lenses of good quality and workmanship are restored to an almost clear and transparent state in 2 minutes and completely cleared in 5 minutes, although the high temperature can affect this. If you want to change a single color change lens, the color of the old and new lenses will be inconsistent. This is because the discoloration performance of the old lens will be reduced due to the long-term use of the discoloration agent. Therefore, in order to ensure the normal use and aesthetic appearance, it is usually recommended to replace the two lenses at the same time.
Where to Buy Bifocal Glasses?
However, if you want to get a pair of bifocal glasses, you can purchase them from Koalaeye Optical. Koalaeye Optical is an online optical store and provides all kinds of glasses, sunglasses and frames, such as blue light blocking glasses, wrap around glasses, progressive glasses, polarized sunglasses, and so on.

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 are the causes of lens damage?
When the force area of the lens is small, the impact resistance of the lens is worse. When subjected to the impact of external forces, the lens will naturally be squeezed and cause breakage.
In particular, some lenses with low degrees and high refractive index are possible to cause this phenomenon. When the frame fell from a height due to wrong placement, there is a collision between the edge of the lens and the ground or hard objects. It will produce a broken or collapsed edge. In the process of the lens falling from high, the impact force is larger, and the stress point is smaller. When the glasses are falling, the upper edge of the lens, the convex groove of the upper frame, squeezes against the lens. The middle part of the upper half is easy to cause edge collapse. In the process of processing the template, the template is not accurate, so that the glasses side and the frame can not be uniform fusion, and the force of the lens is uneven. It will be easy to lead to greater stress in some parts, resulting in edge collapse.
