Pain behind ear when wearing glasses

There are two types of people who wear glasses. One type has eye problems, such as myopia, hyperopia, astigmatism, etc. They need glasses to see more clearly. Another reason is to decorate yourself, such as wearing sunglasses when going out. There are especially many people with myopia. It can be said that people with myopia do not want to wear glasses all day long, because it will hurt behind the ears after wearing them for a long time. Why is this?

After wearing glasses for a long time, my ears feel a little painful. That's because the frame of the glasses is clamped on my ears for a long time, so it feels a little painful. I suggest that you take off your glasses when you are resting or not using them during the day to give your eyes a rest. After a period of adaptation, your eyes will return to normal.

Is it better to wear glasses all the time or only when needed?

First, let's popularize the basic theory. For example, when we say a person is 400 degrees myopic, we are using the standard of looking at a distance of 5 meters. This means that you need 400 degrees to look at about 5 meters. If you look at 0.33 meters, which is the normal distance we look at the computer, theoretically you only need 100 degrees. If you look at 0.33 meters with 400-degree glasses, your eyes actually use 300 degrees of accommodation power. If used for a long time, it will cause fatigue. This is why your eyes become sore and swollen when you look at the computer too much. This is the reason.

With this foundation, you will understand:

If you have 450 degrees of myopia, it is your accommodative power that helps you adjust 300 degrees. And 150 degrees is really not adjustable, so I need myopia glasses to supplement it.

If you often look far away and have 150-degree myopia without wearing glasses, your eyes will always be in a state of tension. Over time, the ability to adjust will decrease and your myopia will easily worsen. Similarly, if you use 150-degree to look close, your eyes are actually also constantly using adjustment. Over time, the ability to adjust will decrease and the degree will worsen.

So my suggestion is: no matter how much myopia you have, you must wear glasses when looking at distant objects at a distance of 3 to 5 meters. If you look at close objects, you don’t need to wear glasses if the degree is less than 200 degrees. If the degree exceeds 200 degrees, you need to wear glasses for close objects, but the degree must be 50 to 200 degrees lower than the normal degree. At this time, it is best to have two pairs of glasses.

For example, if someone has 400-degree myopia, it is recommended that he wear a pair of 200-degree or 300-degree glasses for close vision. Wear it when looking at close objects, such as reading or using the computer. In addition, let’s popularize the consequences of not wearing glasses for myopia. We often see myopic people without wearing glasses, and they often squint when looking at things. Why can they see more clearly by squinting? It uses the principle of pinhole imaging. Let’s take a closer look at what serious consequences of squinting frequently? That is the occurrence of astigmatism and the deepening of astigmatism. What is the reason? Because astigmatism is caused by the uneven cornea of ​​our eyes, if we squint frequently, the vertical curvature of the cornea will be greater than the horizontal direction. The more frequently and longer we squint, the more serious the astigmatism will be. So if you are nearsighted, you need to wear glasses, and the effect will be better if you wear them in the way I recommended above.

The problem of eye deformation Why do eyes become deformed? Will the deformation be more serious for people with higher degrees? The reason is that most of myopia is caused by the elongation of our eyeballs. This is not the only factor, but the main reason. This is physiological. Therefore, the deeper the degree, the more the eyeballs protrude forward, and it looks particularly obvious. This has no direct relationship with whether or not you wear glasses.
