How to select the frame according to the optometry data

Abstract: astigmatism has an axis position, and once the axis position changes, it will cause blurred vision. Therefore, when selecting the frame, it is necessary to ensure that the astigmatism axis position will not change in daily wear. At this time, the boundless frame, the frame is thin, easy to deform, and the frame is not suitable for round frames., Everyone wants to choose a pair of glasses suitable for themselves, but when faced with thousands of frame styles, we can only sigh: “flowers are becoming more and more attractive”, and we can’t start at all. What shall I do? Do you still choose one as casually as before and wear it to make people feel better? As people with new thinking, we certainly don’t want to be influenced by glasses., Each of us will have an optometry before wearing glasses. After the optometry, we will have our power and pupil distance. Don’t let go of these two data easily. They are the sharp tools for choosing the frame next: 1 High myopia (myopia degree is greater than 600 degrees): when selecting the frame, we should consider the lens thickness. We all know that the nearsighted lenses are thin in the middle and thicker in the periphery. At this time, we should select the lens with smaller frame size. At the same time, we should select the frame whose sum of frame size and nose bridge size is close to our own pupil distance according to our own pupil distance. Considering the safety, we’d better choose the full frame frame frame frame , Especially the plate frame is better (can cover the thickness of the edge of the lens). 2. Low myopia (myopia degree is lower than 300 degrees): at this time, the constraint of the frame size on our selection of the frame is reduced, but due to the thin lens, we have higher requirements for the frame type of the frame, so we’d better not choose frameless. 3. People with astigmatism: because astigmatism has an axis position, and once the axis position changes, it will cause blurred vision, so when selecting the frame, we should ensure The astigmatism axis position will not change during daily wearing. At this time, the rimless frame, the slim and deformable frame and the round frame are not suitable.,

everyone wants to choose a pair of glasses suitable for themselves, but when facing thousands of frame styles, we can only sigh: “random flowers are becoming more and more attractive”, and we can’t start at all. What shall I do? Do you still choose one as casually as before and wear it to make people feel better? As people with new thinking, we certainly don’t want to be influenced by glasses.

each of us will have an optometry before we wear glasses. After the optometry, we have the degree and pupil distance. Don’t let go of these two data easily. They are the sharp tools for choosing the frame:

1 High myopia (myopia degree greater than 600):

When selecting the frame, we should consider the lens thickness. We all know that the nearsighted lenses are thin in the middle and thicker in the periphery. At this time, you should select the lens with smaller frame size, and select the frame whose sum of frame size and nose bridge size is close to your own pupil distance according to your own pupil distance. Considering the safety, it is best to choose the full frame frame frame, In particular, the plate frame is better (it can cover the thickness of the edge of the lens).

2. Low myopia (the degree of myopia is less than 300):

at this time, the constraint of the frame size on our selection of the frame is reduced, but due to the thin lens, the requirements for the frame type of the frame are relatively high, so it is best not to choose no frame.

3. People with astigmatism:

because astigmatism has an axis position, and once the axis position changes, the vision will be blurred. Therefore, when selecting the frame, it is necessary to ensure that the astigmatism axis position will not change in daily wear. At this time, the endless frame, the frame is thin, deformable, and the frame is not suitable.

4. Those whose refractive state is hyperopia:

hyperopia lenses are just opposite to myopia lenses, which are thick in the middle and thin around, Moreover, the diameter of domestic hyperopia lenses is generally small (generally 65mm). At this time, the restrictions on the selection of frame are relatively large. For example, those without frame, half frame and large frame are not suitable.

5. Selection of old flower frame:

Compared with those with hyperopia, the selection of presbyopic glasses frame is more demanding, because presbyopic glasses need close pupillary distance, It is 3 to 5mm smaller than the pupil distance (far use) of the glasses we often say, and in addition to the limitation of the lens diameter, whether the size of the selected frame can be done or not should be considered when selecting the frame. The ideal choice is the full frame frame frame frame with small frame.

6. Select the frame according to the pupil distance:

Pupillary distance is the distance between the centers of the pupils of the two eyes when the eyes look forward. The lens shifting operation must be carried out according to this parameter when matching glasses. If the shifting amount of a pair of lenses is too much, it is easy to appear prism effect and cause dizziness and fatigue. Therefore, when selecting the frame, the sum of the frame size and the nose bridge size should be as close as possible to our pupil distance, especially for people with high myopia.

after reading the above points, I should have some experience in choosing the mirror frame. What are you waiting for? Hurry to choose a pair suitable for yourself!
