Myopia sunglasses ^[1]

Traditional myopic sunglasses are not myopic sunglasses in the true sense. ^[3]

(A) stained lenses

With the rapid development of spectacles technology, resin spectacle lenses have entered the eyewear consumer market due to their advantages such as lightness, safety, and light transmittance close to optical glass, and more and more varieties, from no hardening to hardening; from low refractive index From medium refraction to high refraction; from discoloration to dyeing and even to discoloration.

Stained lenses are made by immersing resin lenses in hot water in which organic pigments are dissolved. The color depth can be controlled at the standard level, the entire lens can be dyed to a consistent color, or it can be a gradually changing color.

(Two) new myopia sunglasses

With tinted lenses, there are now myopia sunglasses in the true sense. The new type of myopia sunglasses combines myopia and sunglasses into one, which solves the problem of unclear objects in myopia, and can block ultraviolet rays and have a high value.

(C) the advantages of new myopia sunglasses

1. Blending into one, beautiful and lighter: myopia and sunglasses are integrated into one, more beautiful and lighter.

2. Freely customizable face bend: Freely customizable large face bend design, with a variety of curvatures to match fashion frames and sports frames, to meet the unique and individual needs of users.

3, colorful color choices: a variety of color dyeing film choices to meet your good "color" pursuit.

(I) Color Classification

(1) It is not recommended to wear myopic sunglasses for high myopic users whose myopia degree exceeds 800 degrees. Because the lenses of highly myopic users are thick, and the large frame design of the sunglasses, the lenses are thick and heavy, which is unattractive and uncomfortable to wear. On the other hand, the perception ability of highly myopic users is relatively weak. For example, if they are paired with a pair of colored glasses, a layer of dark fog is placed in front of their eyes, which makes it more difficult to see things. For the same reason, it is not suitable to wear astigmatism and corrected vision below 1.0.

(2) When purchasing myopic sunglasses, give priority to lenses with good impact resistance. Because the use of myopic sunglasses is mostly outdoor, severe activities may cause the lens to fall and the lens to break. ^[7]

(3) If there are fingerprints on the surface of myopia sunglasses, it will also destroy their fashion sense. It is recommended to pay attention to the lens film layer when purchasing, and try to choose a film layer with anti-oil stain and anti-fingerprint functions similar to that of A6 film.

(4) Myopia sunglasses are not suitable for long-term wearing indoors. Over time, it will increase attention and damage to eye health. You must prepare a pair of ordinary myopia glasses. Or consider using intelligent color-changing lenses, which adopt photochromic technology, which can change the color of the lenses quickly and evenly with the change of ultraviolet rays. In the sun, it will become very dark, and when entering the room, the lens will become nearly colorless.

(5) For those who drive, fish, and love sports, it is recommended to give priority to driving polarizers. Because sunlight reflects glare on sand, water, snow, and roads, it often causes eye discomfort and fatigue. The polarizing angles and radians of driving polarizers are designed based on precise optical principles. These irregular reflections can be reflected. Effective arrangement and filtering (such as the principle of blinds), the light is sorted into the same direction into the eyes, making the surrounding scenes look soft without glare.

(6) Myopic sunglasses must go to a professional institution for optometry and glasses, and never buy one casually. ^[8]
