Seven Things You Don't Know About Glasses
1. Some people say that the lens degree should not be too deep when getting glasses, otherwise it will get deeper and deeper?
Answer: This is not true. If lens degree is lower than the actual eye degree, patient will squint when looking far away which will cause the contraction of ciliary muscle to adjust, and the eye is prone to fatigue, which makes the degree more easily deepened.
2. Will I not be presbyopic in the future? (Now myopia)
Answer: Will I not be presbyopic in the future? (Now myopia)
Answer: Presbyopia is a physiological phenomenon, and everyone knows it. This is because the function of the ciliary muscle decreases with age, which makes it difficult to see near (especially reading and writing), so it is called presbyopia. It is just that people with myopia or good eyesight will have presbyopia later. If the degree of myopia is shallow, it can be washed away with the presbyopia, so when you look closer, you can remove the reduced degree of the height number, and you can see the distance unchanged.
3. After getting the glasses , should they be worn often?
Answer: Generally, if the degree is lower(-1.00-2.00), you don’t need to wear it often when you look close. This will not aggravate the adjustment of your eyes. But if it exceeds -3.00D, no matter whether you look near or far, you need to wear it often. If you don’t wear it, the adjustment will deepen if you see the object blurred, resulting in fatigue and depth.
4. Why do some people experience dizziness when wearing sunglasses with a larger arc?
Answer: Some people have this situation, mainly because of sensitive eyes and large curvature of the lens. After assembly, a certain prism effect may occur, so dizziness may occur.
5. Why did people feel uncomfortable when wearing newly-matched glasses at first?
Answer: There are many reasons, A, degree may be different, B, the angle has changed, because the old glasses are deformed and damaged, long-term wearing has formed a bad habit, and it has to adapt to the correct angle. C. The old glasses are worn out. As a result, the lens is blurred and the current object is blurred. Because of the sharpness of the new glasses, the vision suddenly feels much brighter, resulting in a visual impact, so it feels uncomfortable.
6. I have cataracts, can I have glasses?
Answer: First of all, we must determine whether you are in the early stage or the middle or late stage? If it is an early stage, you can get glasses, but if it is in the middle or late stage, it’s useless to wear the glasses. It is recommended to have glasses three months after the operation.
7. After wearing reading glasses, will the degree of presbyopia become deeper and deeper? It is not true. The degree of presbyopia will become deeper and deeper without wearing it. This is a physiological phenomenon and a manifestation of the decline in our adjustment function. Everyone is the same.
