Clear non-prescription sunglasses are a trend.

Clear glasses will not appear old, as long as the choice of their own frame is good-looking, although it is often said that a round face is suitable for angular frames, and a three-dimensional face is more suitable for rounded frames, but the collocation of face shape and frame can not be generalized. A transparent picture frame gives a person a feeling of intellectual, restoring ancient ways of literature and art model. There are a lot of people who use it to reflect their modeling. It seems that there is a pure sense of feeling. And people who use it do not lose the taste of literature and art, and there is a unique personality. Half of the transparent glasses are made of TR material and plate, which is light and comfortable to wear and have many styles.


Eyeglasses in brick-and-mortar stores cost extra.

In order to attract the attention of customers, physical optical stores need to carry out store decoration, and customers need to buy glasses to share the cost, so the glasses in physical stores are more expensive. Physical optical stores have other expenses, such as electricity, employee costs, rent, and so on, which is a big expense, naturally, but also to the customer to share. These are invisible consumption and need to be tied to the customer.



Glasses frame material

Children with glasses can choose a soft silicone material frame. Soft silicone is light to wear and soft at the same time. It is comfortable and does not break easily. The child is young and still in the stage of development, so consider comfort when choosing the frame. A light frame is more comfortable, such as a titanium frame, TR plate, silicone. Or the glasses should be matched according to the child's face shape and pupil distance.


Let the rectangular glasses reflect the fashion aesthetically.

Modern frames are part of fashion and are no longer just medical devices. The person who matches glasses wears glasses, does not hope to expose their shortcomings, but hopes that the glasses can play a decorative role, making up for the shortcomings. The important rule is that according to the face shape, you can choose the appropriate glasses frame to highlight the appearance, to give people a sense of symmetry and balance. For example, people with square faces can wear circular frames and break feelings of edges, and the square frames can add the angular sense of a round face.



How To Choose Better Night Driving Glasses?

Choose and buy glasses to use a special night with anti - strong night driving lens. The demand is to block 80-90% of the strong lights and harmful lights, and at the same time to make the road more clearly. Choose glasses with thicker lenses, they are more durable and protect the eyes of drivers against irritation and accidental breakage. As common sunglasses and color-changing glasses are only suitable for daytime wear, wearing them at night will seriously affect the driver's vision.

Common light yellow night driving glasses can only block a small amount of light, and is not very suitable for night driving glasses standards. Therefore, in the choice of lenses of night driving glasses, we must do the selection and demonstration of the national authority of the formal institutions to test products, to achieve the desired effect in actual use. Don't buy products that are not up to standards from vendors. Such products not only do not block the lights but may affect the driver to see the road ahead, affecting the safety of the train operation.


Testing of aspheric lens

The optical axis of the optical center just overlaps with the visual axis of the eye, which is the most ideal state. Because the light from the edge cannot form a focus on the optical axis, when the optical axis does not overlap with the visual axis (the difference is greater than 2mm), such unclear and scattered imaging results will occur. When choosing frames and aspheric lenses, you need to ensure that they fit correctly, to achieve the best visual and decorative effects. Simply put, due to the special design of the lens, we found through a calculation that the optical center should move down 1mm higher than the pupil for every 2° increase in front inclination angle. Otherwise, the wrong pupil height will cause the lens to look like astigmatism, and cause discomfort. For glasses with aspheric lenses, there must be an inclination angle after wearing. The specific angle varies from person to person.



Each type of store has its own characteristics.

Nowadays, the optical stores in the market can be roughly divided into professional optometry and optical matching stores, fast fashion stores, brand flagship stores, and stores in shopping malls. The benefits of fast fashion optical stores are fast commodity update frequency, and they follow the fashion trend, which can bring consumers quite more choices. The size of fast fashion optical stores is usually not large, so they will use an open showcase design. The color collocation should be able to catch the attention of consumers, to attract customers to make self-service selection and experience.
