We often hear that many people worry about choosing spherical lenses and aspheric lenses. What is the difference between Spherical Lenses and aspheric lenses? Who are they suitable for?
From the appearance of the lens, the general aspheric lens is more beautiful. This is because under the same material and power, the aspheric lens is flatter and thinner than the spherical lens, so most people with higher power will Choose to wear aspherical lenses.
Spherical lenses have excellent impact resistance and are safe and durable. However, if traditional spherical lenses look at the object from the edge of the lens, the object will be distorted. The higher the power, the thicker the appearance and the difference. Because the higher the power, the greater the gap, so it is not suitable for people with a high number of people, but the following people are suitable for wearing spherical lenses:
1. Those with particularly sensitive eyes, including those with high pupil distance and pupil sensitivity
2. For those with squint, the prism effect of Aspherical Lens cannot be used for squint
3. Those who have strict requirements on proportions, such as painters
The aspheric design minimizes the edge difference of the lens, and does not change the shape of the object when looking at the object. Therefore, the surface curvature of the aspheric lens is an aspheric design, which makes it more natural to see things, with less distortion and more realistic viewing. The following people are suitable for wearing aspheric lenses:
1. Those who wear glasses for the first time;
2. Those who wear contact Lenses and frame glasses alternately;
3. People with high myopia;
4. People with high astigmatism;
5. People who have high requirements for image;
6. Those who have high requirements for edge vision, such as drivers;
7. People with high requirements for natural vision, such as paper designers;
8. People who use eyes with high intensity for a long time, such as computer operators
