The nose pad
When you're shopping for a driver's glasses, you can't ignore a nose pad. Choose one that is soft and elastic. This way, it won't make your noses feel depressed or uncomfortable.
How to Perform Glasses Measurements?
If there is no number on the temple of eyeglasses, you can perform glasses measurements by yourself. Now, we will show how to do that.
To measure the glasses’ size, you need to prepare a ruler or a tape first. To measure the frame width, measure the entire horizontal front of the frame, from the furthest extended point on either side. As for lens height, you should measure the vertical height of the lens. As for the bridge, you should measure the part that goes across the bridge of your nose. The temple arms include the front of the frame on either side and the rest behind your ear. The lens width is the horizontal diameter of one lens. So, when measuring these, you should be careful.
After that, you have measured the glasses frame size. If you want to know whether your face is right for this frame, you can read the post: How to Measure Face for Glasses Frames - 7 Steps
If you need a pair of new glasses, you can try Koalaeye glasses. They are stylish and cheap and they are lots of available choices.
Aluminum Night Driving Glasses
These night vision glasses feature advanced HD technology. The aluminum frame is lightweight, allowing you to comfortably wear your driving glasses and reduce glare for safe driving. Because the lenses are yellow, these glasses act as night vision goggles to reduce glare, reflections, and their negative effects, while improving and brightening the visual area. Polarized lenses have a special anti-reflective coating that eliminates intense reflected light and reduces glare and scattered reflections. They can double as day and night glasses, improving clarity around the clock.
Why are rimless glasses so expensive?
Rimless glasses are the design vantage point in the frame of glasses. The structure of rimless glasses requires many higher physical features (flexibility, surface texture, etc.) and machining accuracy than TR, PEI, and other materials. In order to ensure comfortable wear, the common materials are very exquisite. And for processing technology, the frame is the most difficult. It's not just grinding, it's a full polishing, and it's perforating. This is the technical demand and the most time-consuming.
Acetate frame and plastic frame
What is the difference between acetate frame and a plastic frame? Acetate frames are lighter and generally considered to be better than plastic frames. Acetate is known for its hypoallergenicity, so it is a popular choice for people with sensitive skin. Unlike some plastic or metal frames, they can cause allergic reactions.
- The manufacturing process makes the plastic frame more brittle than the acetate frame.
- If the temple does not have a metal bracket, it is difficult to adjust the plastic glasses.
- There are fewer choices of colors and patterns for plastic frame
However, you will notice that acetate frames are generally more expensive than ordinary plastic frames. Spectacle frames are daily necessities that we use for a long time. Therefore, durability is essential, and the life span of the acetate frame is longer.

Application of titanium alloy
Titanium alloy is mainly used in aircraft engine compressor parts, followed by rocket, missile, and high-speed aircraft structural parts.By the mid-1960s, titanium and its alloys were already in common industrial use, making electrodes for industrial electrolysis, condensers for power stations, heaters for petroleum refining and seawater desalination, and pollution control devices.Titanium and its alloys have become a kind of corrosion-resistant structural material.In addition, it is used to produce hydrogen storage materials and shape memory alloys.
