Progressive lenses and single vision lenses
An optical lens that has only one luminosity on a single vision lens and does not have special functions.
The curvature of the front surface of the progressive lens increases continuously from top to bottom, and the refractive power increases gradually and continuously from the distance zone located on the upper part of the lens until the near zone at the bottom of the lens reaches the required near-use refractive power. A pair of glasses can be used. You can see far away, you can see close, and you can see objects in the middle distance.
Use the fishing sunglasses correctly.
Fishing enthusiasts should try to avoid wearing sunglasses that are easy to oxidize and corrode. They should wear sunglasses that are not easy to oxidize and corrode, such as plate frames, aluminum and magnesium alloy, pure titanium, and titanium alloy. Do not put the fishing sunglasses in a high-temperature environment for a long time, and do not immerse the fishing sunglasses in water for a long time. Avoid contact with perfume, insecticide, and other items containing chemical components to avoid chemical corrosion of lenses and frames and better protect your sunglasses. When they are not in use for a long time, please put them in a special bag so that the lenses can be taken good care of.
A saddle bridge is a type of bridge.
The bridge of the nose can make your nose look slimmer. There are two main types. The keyhole distributes the weight of the glasses to one side of the nose rather than the top. It's a good choice for those with a broad nose. The Keyhole Bridge is old-fashioned in the classic style, like a Keyhole. This design creates a small gap in the top part to give the impression of space, thus making your nose look smaller. Saddle bridge is a more modern style and usually goes around your nose with almost no gaps at the top. This close contact will make your nose look tighter.
Who need progressive lenses?
There is no limit to the degree of progressive multifocal lenses. Whether it is nearsightedness, presbyopia or moderate astigmatism, it can be worn, but not everyone can wear it. There are two types of progressive multifocal lenses on the market, one is hard and the other is soft. The main difference between the two designs is the length of the progressive channel. The rigidly designed progressive film has a short progressive path and relatively less peripheral aberrations. In order to ensure vision at various distances, fewer vertical dimensions are required. For example, a teenage progressive film belongs to this design, but because of its short gradual path, the gradation process is too short. Fast. Compared with the elderly, this design is more difficult to adapt; the soft design of the progressive film has a relatively long gradation channel and relatively large peripheral aberrations, but due to its long gradation channel, the gradation process is relatively smooth, which makes it easy to wear glasses It is suitable for people with poor adaptability.
If you are a person who is able and willing to accept new things, understand and adapt to the temporary discomfort caused by progressive addition lenses, we suggest that he can wear a pair, if he has severe hypertension, dizziness and other symptoms, or People who have misunderstandings about progressive lenses and are unwilling to adapt should not try them. Because you first wear progressive multifocal glasses, you may experience: slight dizziness, shaking when walking, and being careful when moving up the stairs.
The perception of space has changed, the perception of the distance of the object, and the perception of depth have changed. New wearers should not drive immediately and do strenuous exercise. When you look close, you need to turn your eyes down, and your eyes are mildly uncomfortable. Seeing an object through the blurred vision area around the lens makes the object blurred. Therefore, when new wearers look at things, turn their heads more, turn their eyes less, try to use the far-use zone, the near-use zone, and the middle-distance zone to see objects.
What is hard coating on lenses?
Lenses are mainly added in two kinds of film: anti-reflection film and hard film (and some manufacturers produce anti-fogging film and mirror film, but not common). The anti-reflective film is mainly by coating the front surface of the lens with multiple layers of transparent materials with different refractive index and thickness to reduce the excess reflected light on the surface of the lens, by using the principle of light interference. The film can be applied to both glass and resin lenses. The way of hard film plating is usually a soaking process. After many times of soaking and cleaning, soaking in an organic solution containing ultrafine silicon element for a certain time, and then keeping it at a certain temperature for 4-5 hours, the fixed polymerization process of the film has been completed. The surface wear resistance of CR-39 coating can be increased by 2-4 pH, which is similar to the hardness of optical glass lenses.
Why You Should Wear Blue Light Glasses?
However, many of our work and social life revolve around looking at a screen for multiple hours every day. Too much exposure may damage our eyes. So, you need to consider wearing blue light glasses. Here are several reasons for you to wear blue light glasses.
Less eye strain: looking at a screen all day can make you feel stressed or you may experience eye and muscle strain. So, wearing blue light glasses can help you to reduce eye strain.
Better sleep: spending time on a screen before bed can make you feel alert. In the same way, a walk outside sunlight can also help you feel alert. So, if you are unable to turn off your device an hour or two before bed, using blue light glasses may help you sleep better.
Fewer headaches: blue light can trigger migraines and exacerbate headache pain. Blocking blue light with special glasses may reduce headaches.
Lower risk of eye diseases: the cornea and eye lens are able to block out harmful UV light from reaching the retina. But, they can’t block blue light. If the retina is damaged, the risk of developing macular degeneration will increase, which would lead to blindness. In addition, blue light can penetrate your retina and lead to macular degeneration-like symptoms and increase the risk of developing cataracts. So, wearing blue light glasses can prevent this.
From the above information, can you wear blue light glasses all day or can blue light glasses damage your eyes? You may have got the answer. So, if you need a pair of blue light glasses, try Koalaeye glasses. They come in stylish and at a cheap price.
