Adaptation period after wearing new glasses
Adaptation period after wearing new glasses
People who wear glasses all have a problem, which is that every time they change their glasses, there will be a period of discomfort. Even after precise medical optometry and standardized mirror making, the vast majority of patients wear glasses clearly and comfortably. Some patients who have not worn glasses or have significant changes in the original lens power may initially experience varying degrees of discomfort.
If the visual object becomes larger (hyperopia lens), smaller (myopia lens), wave motion, mild visual deformation, glare, and ghosting; If it is a progressive multifocal lens, it may feel that the field of view becomes narrower, like jumping, all of which belong to optical phenomena and need to be worn for a period of time to adapt. The adaptation period varies depending on the person and the type of refractive index, ranging from 3-5 days to 2-3 weeks. Some people may even need to adapt for about a month, and the discomfort gradually disappears. If the discomfort is severe and lasts for a long time, it should be re examined in a timely manner.
What factors can lead to longer adaptation cycles?
1. Lens
For some customers who have used old glasses for a long time and have just replaced them with new ones, even if the refractive index does not change, wearing new glasses will still cause short-term discomfort. This discomfort is mainly due to differences in the clarity, transmittance, forward tilt angle, curvature, and height of the nose rest between new and old lenses, which is equivalent to changing the eye environment, so short-term discomfort is inevitable.
2. Diopter
The change in refractive index is the main cause of discomfort with new glasses. Including changes in myopia, astigmatism, and axial position. If the refractive index of new and old glasses changes significantly, it is more likely to experience discomfort and the adaptation period will be relatively longer; The smaller the change in refractive index between new and old glasses, the less likely they are to become unsuitable, and the shorter the adaptation period.
3. Mirror frame
The frame size of new and old glasses may vary, and there may also be discomfort. This is because the size of the frame varies, and the visual field perceived by the eyes also varies, resulting in short-term discomfort.
4. Uncomfortable situation
These possible uncomfortable situations include dizziness, feeling out of focus in both eyes, deformation when looking at objects, such as uneven ground, deformed phone and computer screens, feeling empty when walking stairs, slight swelling and pain in the middle of the eyes, eye soreness, fatigue, and sudden brightening of the environment.
How to adapt to new glasses faster?
1. Regular wear: New glasses should be worn regularly. If you don't get used to them at first, wear them for 3 hours a day and then gradually increase. Wearing more will help you adapt to the new glasses faster;
2. Quiet before moving: The new glasses should be worn while sitting at the beginning, and when it feels better to wear them while sitting, they can be put on for walking or going out;
3. Frequently facing computers: For computer enthusiasts, wearing new glasses when looking far away is more comfortable, and wearing old glasses when looking close is more comfortable. The transition between new and old glasses will be faster.
Of course, the adaptation of new glasses needs to be based on the correct refractive index. If there are any situations during the adaptation period and you still cannot adapt to the new glasses within a month, it is recommended to go to the store and have your vision re examined.
