Characteristics Of Metal SUNGLASSES

Jul 19, 2017

Summer sunlight is strong and easy to hurt glasses so young people must wear metal sunglasses in the summer, plus all day long on the computer so metal sunglasses are protecting glasses from fatigue and damage to the necessities of life.

Sunglasses can reduce the intensity of the sun's eye damage, Metal Sunglasses the glare of the light can cause headaches, sunglasses will have 95~100 filtration effect.

The benefits of wearing metal sunglasses in summer:

1. Prevent ultraviolet rays in sunlight. Ultraviolet rays can damage the cornea and retina, and metal sunglasses completely eliminate ultraviolet radiation.

2. To prevent the irradiation of strong light.

When the eye receives too much light, it naturally shrinks the iris. Once the iris shrinks to its limit state, then people need to squint. If the light is still too much, Metal Sunglasses such as the sunlight reflected in the snow, will damage the retina. Metal sunglasses can filter up to 97% of the eye light to avoid damage.

3, prevent glare.

Some surfaces, such as water, can reflect a large amount of light, and the resulting highlights can disrupt sight or hide objects. Metal Sunglasses Metal sunglasses can use polarized technology to eliminate such glare.

4, eliminate the specific frequency of light. Certain frequencies of light blur the line of sight.

Characteristics of metal SUNGLASSES

1, metal sunglasses also known as sunshade, for shading purposes. People in the sun usually rely on adjusting the pupil size to adjust the luminous flux, when the intensity of light than the human eye adjustment ability, Metal Sunglasses it will cause harm to human eyes. So in outdoor activities, especially in the summer, many people use sunglasses to block the sun, to reduce the eye adjustment caused by fatigue or strong light stimulation damage.

2, according to functional classification: anti-reflective protective lenses, color lenses, painting lenses, Metal Sunglasses polarized lenses and color-changing lenses.

A anti-reflective protective lens: To prevent strong light reflection, see things more clearly and not subject to strong light interference.

B Color Lenses: absorbs light at a particular wavelength, which is the most common type of lens used by sunglasses.

c) Painting lenses: the absorption of a specific wavelength of light, Metal Sunglasses the general degree of the sun glasses are mostly painted to deal with the lens.

D) Polarized lenses: eliminates or weakens the reflection of the non-metallic surface. It can weaken the glare of light that shines on the surface, land or snow, Metal Sunglasses and is suitable for outdoor sports, such as sea activities, skiing or fishing.

e) color-changing lenses: When the strong light irradiation into a colored lens to do protection, suitable for indoor and outdoor use at the same time, but the color change takes a certain amount.

f) Metal Sunglasses clip: The polarizing metal sunglasses designed for the myopia crowd, Metal Sunglasses effectively prevent glare, anti-ultraviolet rays. Night Driving Lenses: block the other side of the car strong light, effectively weaken glare and other harmful light, normal visibility of the road, thus ensuring your driving safety.

3, by color classification: Brown Department, Gray department, Green Department, Red Department, etc., of which the first three lenses of the best color.

A) Tan department: Soft tones, ease eye fatigue, improve visual contrast and clarity, in the air pollution serious or foggy conditions wear better, generally can block the smooth bright surface reflected light, suitable for drivers.

b) Gray system: can absorb the infrared completely, and most of the ultraviolet light, the scene darkens but does not change the primary color.

c) The Green Department: can alleviate the eye fatigue, but will change the scene primary color, the dark green lens light transmittance and the clarity is low, suitable for the sun to wear, when driving is not suitable, the blue lens effectively filters the sea water and the sky Reflection light blue, Metal Sunglasses is suitable for the seaside beach to play, but

d) Red Series: The effect of blocking ultraviolet rays and infra-red is better than that of three kinds, but the light barrier is better for some wavelengths.
