What does the Drop Ball Test have to do with the eyewear industry?
FDA mandates that eyewear products must ensure their safety. Impact resistance is a basic norm for binding glasses and/or lenses in the United States. The FDA does say that a drop ball test must be performed on every glass lens for prescription use. The FDA-regulated eyewear products are common in the everyday lives of the public, and the FDA considers impact-resistant lenses to be an important part of the safe design of these devices. Today, safety lenses are rarely mentioned in our sales, but in the 1990s, when resin lenses first entered the Chinese market and glass lenses still dominated the market, safety lenses were a pretty important concept. At the time, the hardening technology has not been upgraded, and the resin lens is easy to wear out than the glass lens. The eyewear industry is relying on lightness, safety (anti-impact), comfort (anti-ultraviolet) step by step to achieve the market share of resin lenses from 1% to 100%.

Benefits of Blue Light Glasses
In this section, we will show you the benefits of blue light glasses.
- Relieve eye discomfort with blue-light blocking glasses. Excess device usage can lead to computer vision syndrome or digital eye strain. Blue light glasses can enhance your focus and reduce eye strain, resulting in making your eyes feel less tired and improving productivity. Another way to reduce eye strain is to make sure you take regular breaks from the screen.
- Blue light glasses can affect your sleep. Blue light has a high energy frequency that can increase alertness and delay the body’s release of melatonin, which helps induce sleep. In general, you had better not use blue light devices one to two hours before sleep. Blue light glasses can reduce the impact of blue light, enabling you to use your devices before bed and still get a good sleep.
- Blue light glass can help reduce the likelihood of Age-Related Macular Degeneration. AMD is a leading cause of blindness. Blue light blocking lenses can help avoid or delay this condition by preventing blue light from impacting your eyes.
Of course, besides those benefits, there are some other benefits of blue light glasses. For example, blue light glasses can relieve headaches.
Glasses are frequently replaced.
In the United States today, there are more glasses than people. Counting prescription glasses, sunglasses, and over-the-counter readers, there are now more than 400 million pairs on the market. According to the Vision Council, an industry group, they swap out a brand new pair of glasses every two years on average.

Go to a regular hospital to check your eyes
On the surface, pseudo-myopia is the same as true myopia, that is, looking far away is blurred and near looking clearly. But looking at the essence through the phenomenon, the difference between the two is obvious. The so-called pseudo-myopia is due to frequent incorrect use of the eyes. The ciliary muscles continue to contract and spasm, and they cannot get the rest. And the crystals are also in a state of thickening. In this way, the parallel light from the outside enters the eye, and after the thickened lens chamber is flexed, the focus falls to the front of the retina, and it is naturally unclear to look at things in the distance. During this period, the eyeball has no organic changes. If you can take proper rest and treatment, pay attention to eye hygiene, use your eyes reasonably, and hope to restore normal vision. However, if the false myopia is not corrected and treated in time, it will develop into true myopia over time. There are many ways to treat pseudomyopia, mainly relaxation and adjustment, such as application of cycloplegia, acupuncture, physical therapy, improving the learning environment, paying attention to eye hygiene, and doing eye exercises. If you suspect false myopia, you should go to the hospital for an eye examination as soon as possible.
