The principle can be followed when choosing glasses for people with round faces
Choosing the right frames is not an easy task. Choose a color closer to your skin or lighter than your eyebrows for a more natural look. In reality, there is no exact answer to choosing glasses based on face shape. The rule to follow when choosing glasses for a round face is to make up for the lack of a round face by choosing an angular style. The vertical lines of the frame should be narrow.
Disadvantages of Progressive Lenses
It takes time to adapt to the lenses. It can generate poor visual resolution (blur). There is also a geometric distortion of the field of view. Some of the problems with advanced progressive lenses occur when walking up and downstairs. Because the reading correction is at the bottom, the staircase may look like a rebound. However, this is all done to accommodate your progressive lenses, and within about two weeks the shortcomings should disappear. It takes some time to get used to progressive lenses. Changes in vision occur at the rim of the lens, leading to slight changes in peripheral vision. For some people, change is a little difficult. Because the first wear of progressive lenses may occur slight dizziness, shaky walking. One should be careful when they exercise or go Up and down the stairs. Because the sense of space changes, the distance judgment of the object, the sense of depth changes, people who first wear should not immediately drive or do strenuous exercise. When looking closely, the eyes need to turn down, they have mild discomfort in the eyes. The object becomes blurry when they look at it through a blurred area around the lens. Therefore, new wearers turn their heads more and turn their eyes less when they see things and try to use the far, near, and middle distance areas to see the object.
How to buy prescription glasses online
Consumers should choose different styles of frames according to their age and professional characteristics. Because everyone has different face shapes, different interpupillary distances, and different diopters, the size of the frames should vary from person to person.
Lenses are divided into glass lens, resin lens, and PC lens, and you can choose according to your preferences. The glass lens has a stable refractive index, good abrasion resistance, and stable optical performance, but it is relatively heavy and easy to break. Resin lens with high light transmittance is light, safe, and not easy to break, but the surface is easy to wear. PC lens has a high refractive index, but the surface is easy to wear.
What is a progressive lens?
Progressive multifocal lenses are lenses with different upper and lower powers for seeing far above and below for seeing near. The distance from the fixed far 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. Compared with ordinary lenses, there are many advantages. The appearance of the lens is like a single vision lens, and the dividing line of the power change is not visible. Not only is the appearance beautiful, but more importantly, it protects the age privacy of the wearer, and there is no need to worry about revealing the age secret due to wearing glasses.
Since the change of the lens power is gradual, there will be no image jump. It is comfortable to wear and easy to adapt. So it is easy to be accepted. Because the degree is gradual, the replacement of the adjustment effect is gradually increased according to the shortening of the short distance. There is no adjustment fluctuation, and it is not easy to cause visual fatigue. Clear vision can be obtained at all distances in the visual range.
Such a pair of glasses meets the use of long-distance, near-use and various distances in the middle at the same time. It is especially good news for teachers, doctors, music workers, and computer operators, because these people not only need to see far and near objects clearly, but most of the time they also need to be able to see middle distance objects such as blackboards, piano scores, and computer screens. . This is not possible with any lens other than progressive lenses.
Benefits of Saddle Bridge Glasses.
The most common type of plastic bridge is called a saddle bridge. The style is very comfortable because it distributes the weight of the glasses over a larger area rather than focusing on smaller points, like adjustable nose pads. Saddles are known to cost less to repair because they have fewer moving parts and are possible to maintain their fitness. There is now a new saddle bridge-type transparent silicone cushion for a screw-type nose pad. It is made of medical-grade soft silicone. It can be bent and is very soft. To fit the curve of the nose, a plastic frame with a saddle or keyhole bridge can slip off the nose without proper support. Silicone is a soft and elastic material that can be formed according to the contour and shape of the nose.
Why are titanium glasses so expensive?
Pure titanium can guide the electron wave to produce ions so that the current tends to ionize, and positive and negative ions can reduce the harmful effects of the body's biological current chaos caused by electromagnetic waves. To the human body, it has a great health care role. It avoids fatigue, muscle stiffness, soreness, and other symptoms or problems.
