How To Choose Better Night Driving Glasses?

You should select light alloy material and polymer material with memory, collision resistance, and low friction coefficient characteristics. It can effectively prevent the damage to the eyes and face caused by the friction of the broken lens frame during use. Because of its specific molecular structure, the chemical resistance is good. In the high-temperature environment. it is not easy to deform and can withstand 350 degrees in a short time of high temperature, not easy to melt and combustion. The glasses made of this material are light and strong, and the ears will not be uncomfortable because of wearing the glasses for a long time.



Where can use the glasses emoji?

Glasses emojis are commonly used in glasses-related social media posts and are used to refer to things that have a point of view or demand only a little direction (for example, a museum exhibit, a movie, or a beautiful viewing platform). Although glasses have become a hot fashion accessory in recent decades, they still mean bookish or clever to a certain extent.


Are titanium glasses really more expensive?

Due to its lightweight, corrosion resistance, non-allergic and memory quality, titanium is becoming a new type of glass frame material. But titanium frames are more expensive than other metal, sheet, or plastic frames. Titanium is not a rare metal. It has the fourth-largest reserves after aluminum, iron, and magnesium, and is 16 times more than the world's copper, nickel, leads, and zinc combined. Scarce resources are supposed to have higher prices. With so much titanium in store, why would titanium frames be more expensive than frames made of other materials?



Heart-shaped face with angular glasses

The heart-shaped face is also a common face shape in daily life. This face shape is somewhat similar to the inverted triangle face shape. Generally, the chin is a relatively sharp face shape. For this type of face, the most important thing is to modify the cheekbones above the nose to highlight the slenderness of the chin. Therefore, it is better to wear a pair of angular glasses, which can effectively modify the facial lines and look more perfect.


What are the causes of lens damage?

When the force area of the lens is small, the impact resistance of the lens is worse. When subjected to the impact of external forces, the lens will naturally be squeezed and cause breakage.

In particular, some lenses with low degrees and high refractive index are possible to cause this phenomenon. When the frame fell from a height due to wrong placement, there is a collision between the edge of the lens and the ground or hard objects. It will produce a broken or collapsed edge. In the process of the lens falling from high, the impact force is larger, and the stress point is smaller. When the glasses are falling, the upper edge of the lens, the convex groove of the upper frame, squeezes against the lens. The middle part of the upper half is easy to cause edge collapse. In the process of processing the template, the template is not accurate, so that the glasses side and the frame can not be uniform fusion, and the force of the lens is uneven. It will be easy to lead to greater stress in some parts, resulting in edge collapse.

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.
