Eyeglasses have become a necessity for many people to live on a daily basis. Its mission is not only clear from the requirements previously seen, but more importantly it is a comfort to wear. However, our glasses are so slender, often deformed, and often wearing a pair of deformed glasses has a great impact on our eye health. Here, Yushan glasses provide you with a list of distortions and hazards that are common in your life:
One, horizontal tilt, left and right mirror circle height inconsistent
Common causes of this situation are:
1. The height of the left and right temples is inconsistent;
2. The nose of the glasses frame is tilted;
3. The height of the wearer's ears is inconsistent.
Wearing this type of frame for a long period of time can cause dizziness and fatigue due to the fact that it cannot pass through the optical center of the lens and cause a certain prism effect. In the long term this may cause the eye to shift toward the center point.
Second, the horizontal shift of the glasses frame
Common causes of this situation are:
1. Most of the situations are caused by inconsistencies in the outside angles of the temples, especially the relatively large shifts, which are related to the opening angle;
2. The inconsistencies in the position of the nose pads and the left and right sides are easy to observe;
3, the length of the left and right temples inconsistent, the side of the bias is too short, so the glasses to one side;
4. The width of the left and right faces of individual wearers varies greatly or the left and right ears have different positions.
Wearing this type of frame for a long time will cause dizziness and blurred vision due to the inconsistency of the optical center of the lens and the peripheral degree and the prism effect, which will cause the central main viewing point to be misaligned.
Third, the glasses are not suitable for high and low position
Common causes of this situation are:
1, nose pads position and the wearer's nose does not match;
2. The length of the temple's bending point is not suitable;
3, the selected frame is too large or too small.
Wearing this type of frame for a long period of time may result in unclear vision, dizziness, and eye-opening due to failure to pass through the center of the lens.
Fourth, the legs are too loose or too tight
Common causes of this situation are:
1. Spectacle frame outside the temple or expansion;
2, the frame of the spectacle frame is too large or too small;
3, the deformation of the nose bridge glasses.
Wearing this type of frame for a long period of time can seriously affect the wearing comfort, and the overly tight temples will oppress the temples and cause pain.
