Wearing time

If the glasses are worn for a long time, you can relax other conditions and choose a lighter frame to reduce wearing fatigue. If the glasses are only

worn when the eyes are intensively used, such as reading or watching TV, the frames can be selected completely according to personal needs.

vision condition

People with high myopia should not choose semi-rimless or rimless frames, because thicker lenses paired with rimless frames are not only

unsightly but also easily damaged. People with high degrees of astigmatism should not choose frameless frames, because lenses with frameless

frames will cause the astigmatism axis to shift after long-term use, resulting in deformation of the objects being viewed.

1. If the purpose of wearing glasses is largely to match the image and the occasion you attend. At the same time, if your vision condition does not

place high restrictions on frames, you can choose according to your specific needs.

2. People who often engage in extensive physical activities and sports should choose frames with relatively compact frames made of plastic

sheets to reduce the chance of damage to their glasses due to accidental falls. It is also recommended to wear contact lenses when exercising.

3. People with busy work and frequent business trips can choose frames made of memory materials to prevent the frames from being deformed

and damaged due to frequent taking on and off, being thrown around, or being dropped due to improper placement when taking trains or airplanes.

Style 

Looking at fashion, with the personalization of consumer demand, the fashionable function of glasses is increasingly valued. The choice of style

should be combined with the current popular colors and elements. At the same time, referring to the corresponding styles to decide what materials

to buy frames will be targeted.

In terms of color 

check the depth. Place the glasses flat in front of your eyes and observe whether there is any difference in the color of the temple legs under the

same light intensity. Sometimes due to processing errors, the color of the left and right temple legs will be asymmetrical.

In terms of craftsmanship 

look at the details. Craftsmanship is the guarantee of the quality of the frame, and whether a pair of frames has excellent craftsmanship is often

reflected in the details.

Take a look at the welding points

Pay more attention to the welding points of metal frames to see if there are any cracks. Due to the thermal effect during welding, the stress

structure of the material is changed, or false welding, material fatigue, etc. make it prone to fracture when stressed.

Second, look at the temples, whether the two temples are flat. Place the frame flat on the table and check whether the contact points are floating.

If one side is high and the other is low, you will need a professional to adjust the temples to achieve left-right balance and up-down symmetry.

Third, look at the frame. Pay attention to whether the stipules of the frame are symmetrical on both sides and whether they are securely fixed.

For metal frames, you can use your fingernails to pick them to see if there are any scratches on the paint surface. For frames made of plastic

sheets, carefully observe whether there are plastic particles or roughness on the surface.

Look around for tightness, open and close the temples, and feel the elasticity.

It is generally believed that the tighter the better, which means that the screws are not lubricated enough, which can easily cause damage to the

temples.

Too loose is not good, because the screws may not be tightened. Moderate tightness is best.
