What Are Varifocal Glasses?
Varifocal glasses, also known as varifocals, varifocal lenses, PALs, or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between. This allows you to see all distances and focus points through just one lens. Varifocal lenses are typically used when you have two prescriptions, one for distance and one for reading.
There are three regions of a varifocal lens which are distant zone, intermediate zone and, near/reading zone. Usually, the upper portion of the varifocal lens is the distant zone and the bottom portion of the varifocal lens is the near or reading zone.
One of the benefits of varifocal glasses is that you do not need to prepare 2 separate pairs of glasses or need to switch between frames for different vision needs.
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.
Metal frames have many benefits.
It has a certain hardness, good softness, good elasticity, wear resistance, corrosion resistance, gloss, and good color and luster.?For example, for the high nickel alloy frame, nickel content reaches more than 80%. It mainly has nickel-chromium alloy, manganese nickel alloy. High nickel alloy’s corrosion resistance is better. In addition, the material elasticity is good.?Titanium frame has a high melting point, light material, strong corrosion resistance, and solid electroplating. The eyeglass frame that uses pure titanium is deft and comfortable, more in accord with human body engineering. And flexibility is good, long-term use is not out of shape. And they do not fade, do not cause skin allergy, relatively durable.? Memory titanium alloy frame refers to a new alloy made up of nickel and titanium according to the atomic ratio of 1:1.?Memory titanium is more resistant to corrosion than high nickel alloys but less resistant than pure titanium and β-titanium.
Does a long-face suit wear transparent glasses?
A long face gives people a sense of being relatively thin, so it is best not to wear a transparent, thin frame, or it will show a longer face. It is best to wear glasses with wider rims and darker colors. Compared with women and men, because the overall image of the difference is relatively large, in the selection of glasses, it is best to foil the characteristics of the face and highlight the overall contour of the face. At the same time, the man with a lighter skin color can choose a lighter color frame like the tortoiseshell gold silver frame. People with dark skin color can choose a heavier color frame, like red, black, and so on.
