How Are Glasses Made?
In this section, we will show you how glasses are made. Here are a few steps.
- Eyeglasses lenses are first made by an optician reviewing your prescription and taking a lens bank that closest matches your prescription.
- The optician puts the lens bank into a grinding machine and grinds it into a shape that matches your prescription even closer.
- Then the glasses lenses are edged and cut into a shape that fits the frame you chose.
- Last, put the cut lenses into a solution so as to protect them from scratches, then give them a tint and more.
After all steps are finished, the glasses are made successfully.
What is a titanium glasses frame?
Titanium is a metal that has long been used in aerospace, and even in cutting-edge defense because it is so strong and lightweight. Chemically stable, the material is widely used in artificial joints. One thing to emphasize, the titanium welding process is very demanding. The production cost of titanium and titanium alloy glasses is high, and the process has special high requirements in cutting, stamping, welding, and electroplating (for example, welding must be completed in a vacuum), so the price is relatively expensive.
To protect the lens.
Avoid getting chemicals on your glasses, and if you do, rinse with water immediately. If there is sweat and grease on the glasses, they should be washed to avoid corrosion. Do not use clothes or towels to wipe the lenses. Rubbing the lens with a rough cloth can cause scratches on the surface of the lens. So it is best to use special glasses cloth when you wipe the lenses, and when you wipe the glasses, you must hold the glasses on one side of the frame with your hand, and then gently wipe the glasses with the glasses cloth. Remember not to overexert, otherwise, it is easy to cause frame and lens damage.
What is a drop ball test?
The Drop Ball Test, known as the Basic Impact Test, is an Impact Test administered by the Food and Drug Administration to determine the safety of eyeglasses. Eyeglasses (sunglasses, exercise glasses, near-sightedness glasses, reading glasses, etc.) are a category of medical devices covered by the Food and Drug Administration. When glasses are exported to the United States or put on shelves on Amazon,eBay, and other platforms, they need to be registered by FDA. Besides the product listing, when the product passes the customs, the company may be asked to produce a Certification Statement of Impact Resistance stating that the product meets 21CFR801.410 Drop Ball Test requirements.
What Do Progressive Glasses Mean?
Progressive lenses, also called PALs, are the most popular multifocal lenses today. They offer an effective and great-looking vision solution for individuals with presbyopia. The main benefit of progressive lenses is that they do not have a visible line bisecting the lens, but rather a seamless and gradual change in power as you move down the lens.
Rather than two or three distinct zones, progressive lenses offer a smooth transition of focal powers that covers the total range of clear vision from close to far and every point in between.
