Learn the 9 Necessary Parts of Glasses
Rims: the rims lend form and character to your eyeglasses and they also provide function by holding the lenses in place.
End pieces: they are small parts on the frame that extend outward and connect the lenses to the temple.
Bridge: it is the center of the frame that rests on your nose and joins the two rims together.
Hinges: hinges sit between the end pieces and the temple, allowing you to close your glasses folding the temple inward.
Lenses: lenses are the essential parts of eyeglasses. They are clear pieces of glasses, plastic or other lens materials held in place by the rims. The lenses are crafted and shaped with your unique prescription to help you to see clearly.
Screws: they are the small metal fasteners near the hinges and they are used to connect the end pieces with the temples.
Nose pads: nose pads give your glasses a more comfortable and secure fit. They are the round plastic pieces under the bridge that sit on your nose.
Pad arms: pad arms are able to extend from the rims and hold the nose pads in place. They are adjustable to fit the natural shape of your face.
Temples: temples are the long arms on both sides of the frame that fit over your ears for a snug fit.
These are all the 9 essential parts of eyeglasses. Knowing the name of parts of glasses can help you to repair them once they are broken or crooked.
What are the benefits of Silhouette?
The wonderful style suits both men and women. The glasses are made of strong, reliable, and not heavy metal. They adopt a screw-free design and high-quality process. The glasses are made of titanium alloy temples and are highly ergonomic. They are not heavy and elastic (only 1.8 grams in weight), independent of momentum changes and extreme gravity. The temples and nose pads are made of hypoallergenic titanium alloy. With no screws and hinges, they provide optimal safety in space conditions.
What is blue light?
To prevent blue light, we must first understand what blue light is. The visible light with a wavelength range of 400-500 nanometers is called blue light. The light sources used in daily LED lighting and display products, including mobile phones, flat panels, and TVs, are mostly LED light sources excited by blue light. However, not all blue light is harmful to the human body. The human eye has an extremely low tolerance to blue light radiation in the 400-440 nanometer range. When the light intensity enters this threshold, photochemical damage is likely to occur. However, blue light radiation in the range of 459-490 nanometers is essential for regulating the human body's circadian rhythm and can affect the secretion of human melatonin, which in turn has an impact on the body's biological clock, alertness, and mood.
Scientifically effective anti-blue light lenses must not only block harmful blue light but also cannot filter beneficial blue light. Most of the ineffective anti-blue light products on the market currently have two types of problems. One is that there is almost no protective effect on the blue light in the vulnerable zone of the human eye. The other is excessive protection, shielding the blue light spectrum in the beneficial band so that the blue light that is beneficial for physiological adjustment cannot enter the human eye. At the same time, the color of the lens is yellow, which is prone to color shift, aggravating visual fatigue, and even inducing the risk of myopia.
Benefits of MR Lenses
It is made of MR series material of Mitsui Chemical, Japan. The biggest advantage is that it is both thin and has good optical properties. Besides, the material has good impact resistance and toughness, so it is not easy to be deformed or broken. Wearing such lenses not only looks more beautiful, but clear and comfortable, and safe at ease. Using a lower density polyurethane material, the lens is lighter and thinner, making it more comfortable to wear. The higher machining success rate increases the processing efficiency and reduces the processing cost. The film compatibility and dyeing properties of MR™ are better than those of ordinary materials, which can improve the quality of functional lenses like photochromic lenses and myopic sunglasses. MR-8™ combines high refractive index, high Abbe number (for better imaging), and better processing performance, suitable for rimless, half-frame, and other glasses, which are less broken and safer. MR-7™ provides better dyeing performance, faster and more uniform color application, and can be used for myopic sunglasses. MR-8 Plus™ is safer and further improves the impact resistance of the lens while maintaining the high Abbe number of MR materials.
Design and Fashion of KOALAEYE Eyewear
Women's glasses, which are functional and sexy, can add so much to an outfit and even serve as a personal expression.

With different styles, the feel and appearance are better. They can effectively reduce the pressure of the bridge of the nose. The stylish style is popular with most people.
What Are Pinhole Glasses?
Pinhole glasses, also called stenopeic glasses, are plastic eyewear with hundreds of pinhole-sized perforations in place of lenses. Pinhole glasses are mostly used to improve refractive errors in the eye because they shield the eye from indirect rays of light which can distort vision. This would decrease the blur circle on the back of the retina.
The shape of the lens is also important.
Aviator and cat-eye glasses should be avoided, as both will cut off the base of the prescription, resulting in poor reading vision. Instead, they should opt for shorter frames with rounded edges, such as bull horn frames, vintage wingtips, round frames, and oval frames.
