The Cold Knowledge You Don't Know About Glasses

1. The degree can't be matched too deep, will it be worn deeper and deeper?

This statement is incorrect. If the power is not enough, the patient will squint his eyes when looking far away, causing the ciliary muscle to contract (adjust it), causing eye fatigue, which makes the power easier to deepen.

2. Will you not be presbyopic in the future? (Now myopia)

Presbyopia is a physiological phenomenon, everyone knows it. This is because old age and decreased ciliary muscle function make it difficult to see near (especially reading and writing), so it is called presbyopia, but people with myopia or presbyopia with good examples should hesitate. 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 the glasses are matched, should they be worn often?

Low myopia. Since it does not cause a very significant decrease in vision, it can be worn for a long time. It is only worn when using the eyes at ordinary times, and it is not necessary to wear it when going out or close. However, if the power is relatively high, the vision will be significantly reduced, and the viewing will be very blurred, and it needs to be worn for a long time. If you don't wear it, it is easy to cause eye fatigue, and the degree of myopia will increase faster and faster over time.


4. Some people will experience dizziness when wearing sunglasses with a larger arc?

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 the new glasses feel uncomfortable at first?

There are many reasons, A, the degree may be different, B, the angle has changed, because of the deformation and damage of the old glasses, long-term wearing has formed a bad habit, and it has to adapt to the correct angle. C. The old glasses are caused by wear and tear. Blurred, the current object is blurred, and because of the sharpness of the new glasses, the vision suddenly feels much brighter, causing a visual impact, so it feels uncomfortable.


6. Does the child have pseudomyopia?

False myopia must be increased and decreased. One increase is to increase the duration of outdoor activities. One reduction is to reduce the time of using eyes at close range. Once the child finds that his vision has decreased or his vision is blurred, he should go to the Provincial Eye Hospital for a formal mydriatic refraction to get the child's refractive status.

Due to the extremely long time for online classes this year, during the epidemic, many children took online classes at home. Many children have very good eyesight during physical examinations before the holidays. After the holiday, my myopia went up in no time. Some children are indeed myopia. However, there are some children who look at the blackboard blurry or have myopia. After refraction of ciliary muscle palsy, they are actually in a state of face-up. Decreased vision or nearsightedness is related to accommodation cramps caused by using eyes at close distances for a long time. This part of the child is pseudo-myopia.


7. Do the reading glasses get deeper and deeper?

It cannot be said that reading glasses will become deeper and deeper without wearing them. This is a physiological phenomenon and a manifestation of the decline in our regulatory function. It is the same for everyone.


8. How do I sometimes feel something flying around like a mosquito?

This phenomenon may be floaters. If it happens occasionally, it will not increase. It may be a physiological contract. Often it may be pathological. It is caused by intraocular diseases, hemorrhage or degeneration of the vitreous. Turbidity, you need to go to the hospital for treatment.
