Why new glasses will produce discomfort


Some users always feel uncomfortable after wearing the new glasses. What is the reason? Is there any way to solve it? Maybe we can offer some opinions for reference.

1: New glasses need a certain adaptation period. Although the new glasses have the same luminosity as the old glasses, the old glasses will have many differences in clarity due to the adsorption of fumes, impurities, Revo damage, and oxidation. When wearing the new glasses, the new glasses will feel brighter and may produce slight dizziness. Individual eye sensitivity is different. Sudden changes in visual brightness will also make your sensitive eyes slightly uncomfortable. You can fully adapt after wearing it for 3-7 days.

2: The new optometry power needs a certain adaptation period—the new eyeglasses are prepared according to the new optometry power. If there is a difference in luminosity from the old lens (such as an increase in degree), it will also change the refractive habits of the eyes and need to be adapted to wear; The adaptation period is generally 6-15 days.

3: The initial wearing with astigmatism requires a certain period of adaptation. Customers who wear astigmatic lenses for the first time sometimes tend to have a sense of shaking and distortion of their vision. However, after an adaptation period of 7-15 days, the correct astigmatism of optometry can provide you with more direct visual effects and eliminate visible ghosting. New glasses dizzy is very common at the beginning, so there is no need to worry about it.

4: Problems that are easy to encounter when wearing new glasses

(1) What should I do if the new glasses are worn unevenly or slipped down?

After processing each pair of frames, we will strictly adjust them following national standards to ensure the balance and coordination of the overall posture of the eyeglasses frames. Due to the peculiarities of online glasses, it is impossible to adjust them in person according to your facial features. There may be situations such as the uneven wearing of the frame and the incomplete fit of the nose pads. It is recommended that you go to a regular eyewear shop to adjust to new glasses (friendly reminder: all are free). Do not adjust yourself because you do not have professional tools. Forced adjustment may damage your glasses.

(2) Why do you feel that the ground has become higher?

 When people measure the distance visually, they are based on the original vision (clarity) after repeated practice and compare it with the space seen. Some blurry people feel far, and some clear ones feel close. The glasses improve binocular vision, and naturally, you will think that the ground is higher. Myopia glasses are concave lenses. When the line of sight looks down at the bottom through the lens, the line of sight passes through a bottom-down prism. The effect of the sharp-edged image shift prism raises the ground. Presbyopia spectacle lenses are convex lenses, and when you look down on the basis, you will feel that the earth is hollow. Suppose the glasses only improve the visual acuity of one eye, or the degree of improvement of the visual acuity of both eyes is different. In that case, the floor will inevitably be uneven. The ground is flat and not raised, so this is a wrong feeling.

 (3) Why are some people still unsuitable after a while?

 Suppose you wear new prescription glasses that improve your eyesight and engage in activities you are already familiar with. In that case, you need to constantly adapt to the visual distance and continuously experience the comparison to the actual distance. It takes a long time to get used to new glasses, but other problems may exist if the adaptation period exceeds one week. For example, weak people with blood circulation problems need more time to correct the illusion and feel more difficult. Therefore, if there is no need to improve your eyesight, you should keep your original vision when you wear new prescription glasses.

 (4) How to better adapt to the new power glasses? 

The new power glasses will cause visual errors, which will cause difficulties for people's actions in a short period. To eliminate visible mistakes, you must not be too hasty. It needs to be completed gradually, such as sitting and wearing new prescription glasses in the first week and wearing them indoors in the second week. , Wear it for outdoor walking in the third week. Or choose the good according to the individual's different situations, and re-establish the collaborative relationship between vision and body is certainly possible. Still, the time required for other people is additional.

(5) Do the eyes adapt to the glasses, or do the glasses adapt to the eyes? 

Some people mistakenly understand that glasses should adapt to the eyes, and the eyes should not be adapted to the glasses. If the new glasses are uncomfortable, it is considered that the glasses are not suitable, the power is inaccurate, or the quality is not good. If the eyes adapt to this kind of glasses, it is harmful to the eyeballs vision, and myopia will deepen. The actual situation is far from simple. The new prescription glasses bring us new vision. Such as: 

√The new eyesight.
√New color vision.
√New horizons that we need.
√The form and eyesight that we don't need (causing dizziness and inconvenience).
These problems are unavoidable and a process that must pass through. Therefore, the eyes have to adapt to the new glasses.
