Choose glasses according to your face shape
Choosing the right frame shape can balance facial proportions, highlight advantages, and modify shortcomings. Here are professional recommendations for different face shapes:
Round face
Choose square or rectangular frames with sharp corners to add a sense of line to the face and avoid round frames.
Square face
Choose round or oval frames to soften the jawline and avoid right-angled frames.
Long face
Choose large, dark, and decorated frames to shorten the visual length of the face.
Heart-shaped face
Choose a frame with a wider bottom to balance the proportions of the forehead and chin.
- When trying on, make sure that the upper edge of the frame is at an appropriate distance from the eyebrows and does not press on the eyebrows
- The temples should not clamp the head, and you should feel comfortable and uncompressed when wearing them
- The width of the frame should be equivalent to the widest part of the face, avoiding being too large or too small
Lens knowledge
Understanding the basic parameters and characteristics of lenses can help you choose the lens that best suits you:
| Parameter |
Description |
Selection suggestion |
| Refractive index |
The ability of the lens to deflect light, the higher the value, the thinner the lens |
The higher the degree, it is recommended to choose a high refractive index (1.67 or 1.74) |
| Abbe number |
Measure the degree of lens dispersion, the higher the value, the clearer the vision |
Generally choose above 30, and you can choose above 40 for high definition |
| Material |
Resin (light, impact-resistant), glass (clear, heavy), PC (super tough, sports) |
Choose resin for daily use, PC for sports, and glass for extreme clarity |
| Functional coating |
Anti-blue light, anti-ultraviolet, anti-reflection, anti-scratch, anti-fouling |
Choose according to the use scene, anti-blue light is recommended for office workers, and anti-UV is recommended for outdoor |
Recommended practice
- Choose the appropriate refractive index according to the degree
- Choose well-known brand lenses, the quality is guaranteed
- Choose functional coating according to the use scene
- Regularly check the wear of the lens
Avoid doing
- Don't just look at the price and ignore the quality of the lens
