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.
Benefits of Progressive Lenses
Progressive lenses are different from traditional reading glasses and bifocal glasses in that bifocal reading glasses have to constantly change the focal length, causing fatigue. And there is no clear dividing line between the two focal lengths. They are more comfortable, more beautiful. When you see far or see near, a pair of glasses can be done, so they become the best choice for old people little by little.
Progressive lenses allow multiple fields of view to be merged into a single lens with no discernible difference between the fields themselves. Degrees of the lens vary gradually from far to medium to your full reading. This is why progressive lenses are often regarded as no-line bifocals or trifocal points.
A service is also a form of discount.
The eyewear industry itself is a service industry, and good service can increase sales. If they sell inferior glasses and gifts, they are destroying the brand. Optometry itself belongs to the service, when people are choosing glasses, they must include this kind of service. Consumers are willing to come to optical stores in order to get better service. Therefore, reception, recommendation, testing, and other services should be done. Such as door-to-door delivery, door-to-door product experience, introduction and recommendation, free maintenance and repair, add good value-added services, which is more likely to make consumers buy. This is also a form of promotional activity.
How long does it take to get used to progressive lenses?
Because the adjustment of each eye is different, so there will be some differences in the adaptation period. It usually takes about two weeks to get used to it. Probably many young people are familiar with this kind of lens, so they adapt to them for only a week or so and can restore the normal visual effect. If it's been two weeks and you still feel that you can't see clearly, or you have the feeling of nausea, etc., then you need to test and adjust. You need to go to the hospital to see the specific case, to find out whether it is a quality problem of the sunglasses, or there are some artificial reasons. If there is a problem, we should also replace the lenses in time, otherwise, it may lead to the problem of visual fatigue. Therefore, it is still necessary to promptly confirm the case of optometry, and then replace the appropriate glasses.
