Why Do Blue Light Glasses Have A Yellow Tint?

How to know your face shape to choose glasses?

To determine your face shape and spectacle styles that will look best on you, pull your hair away from your face and look directly into a mirror. Look closely at your face and head. You need to measure your forehead width, cheekbone width, jawline width and face length.

After measuring, you need to consider your facial features. There are a few characteristics tied to specific face shapes. For example, a rounder jawline is typically tied to a rounder face shape, a pointed chin is closely related to a heart-shaped face. And you need to take note of the angles and contours of your face to see they are soft or sharp or pronounced or not.

Then you can check whether you have a round shape face, squared face or others.

Round face shape: the forehead round at the hairline; the width of your face is the same as the length; the jawline round with very subtle angles, and the length of your face is the same as the width.

Square face shape: the hairline follows a straight line; there are minimal curves to your cheekbones; you would have a strong and squared jawline.

Diamond face shape: the width of your face is smaller than the width of your cheekbones; the cheekbones significantly wider than your forehead and jawline; you may have a narrow chin area; the length of your face is the same as the width.

There are also other face shapes. You can click here to know more.


Are titanium glasses frames worth it?

The maintenance cost of prescription titanium glasses is low. Apart from the durable feature, they hold their shape. It doesn't break on the ground. Even if the lens breaks, the frame will not break. You just need to replace the lens, do not have to pay for a new one. In other words, you don't have to spend a lot of time taking care of them, and you can make sure they last for years. It doesn't make your allergies worse and lasts for years. If you've ever broken a glass frame, titanium might be the perfect material for you.



Why do glasses with the same prescription feel different?

The old glasses 'remodeled' your eyes. Sometimes, all data on optometry and processing are accurate, and the spectacles equipped are in full compliance with the prescription for optometry, or the power of new spectacles is exactly the same as that of the old spectacles, but you will still be dizzy when wearing the new spectacles. This is because the old glasses 'remodeled' their eyes during long-term wear. For example, the old glasses used by some people have been severely deformed. The temples are no longer in the same plane, and the optical center area of the lens will deviate from the interpupillary distance measured by the glasses at that time. However, the wearer does not mention this situation, and the eyes gradually adapt to this kind of deviation. After putting on a new pair of glasses, you will not adapt to them.


Polygonal frame

Polygonal glasses frame is derived from square glasses frame. Some of the frames belong to mechanical cutting, and the lens has an exquisite diamond design, very popular with consumers. The irregular frame makes the glasses more angular and makes the frames less monotonous. It's more stylish and trendy. Gold is more popular, but the price is not high.



Half frame glasses

The half-frame glasses are more appropriate. A round face is wide on the left and right. For the half-frame, because it doesn't have a line underneath it, it will make the face look rectangular. Wearing the full-frame will make the jaw look narrower, and the jaw of a round face is narrow, so wearing the full-frame will make the jaw look narrower. Wearing a half-frame lengthens the jaw and makes up for the lack of a round face. On the other hand, full-frame glasses are more suitable for long faces.


How do I know what size glasses frame I need?

With unified factory product size, why others can wear without problems, but there is a problem when I wear the glasses? There are differences between the contours of each person's face, including factors such as the width of the head, the distance between the ears and the corners of the eyes as the crow flies, the thickness of the bridge of the nose, and so on, which involves ergonomics. But there is one thing we can agree on. When people with the same ear distance wear the same type of glasses, they have different feelings, even if the arm length of the glasses is the same. People with fatter faces will feel uncomfortable. The face will be uncomfortable because the ear distance is the same, but the face width is not the same, resulting in an increased oblique distance of the temple, resulting in a sense of pressure.

It is very simple to solve this problem. You need to look at a variety of parameters in the frame of the glasses, including the total width of the frame, the length of the arm. These parameters will be reflected in a qualified spectacle frame.
