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%.


What Are Standard Progressive Lenses?

Standard progressive lenses are a type of progressive lens with plenty of room at the bottom for your near vision. If you need to see something far away and up close, such as a book or magazine, this lens is for you. Transitioning between these viewing areas is often painless for your eyes.



Method of wearing the contact lens

Wash your hands before putting on contact lenses, and be careful not to leave long nails, to avoid contamination of the lens by bacteria and nail scratches. Place the contact lens on the tip of your index finger, face-up, and pull your upper and lower eyelids apart with the middle fingers of both hands. Look straight ahead and place the lens gently into the eye (attached to the cornea). Remove the index finger and look down so that the lens is attached to the cornea, and slowly relax the eyelids with the middle fingers of both hands. Blink gently several times (or roll your eyes) to remove bubbles.


The frame needs to match the face shape.

Based on the basic principle of modifying the face shape, avoid wearing frames that are too similar to your face shape as far as possible, so as not to cause the lines of the face to be overly emphasized. The combination of the glasses and the face shape determines whether the glasses are suitable for you or not. Usually, we use the shape of the glasses to modify the shortcomings of the face shape. For example, for a man with a square face, round glasses are more suitable.



Armani glasses

The handmade frame, superb craft, and workmanship make the charm of the Armani spectacle frame show in front of everyone. The medical environment-friendly silicone nose pad is designed according to the structure of the human nose bridge, which not only fits the nose more but is very comfortable. The prices of the Armani frame are basically around 1500 yuan.


The Advantages of Trifocal Lenses

The greatest advantage of trifocal lenses is that they have three prescriptions in one, which means that not only do you not have to buy three separate pairs of glasses, but you also won’t have to constantly change them as you go about your day.

Another advantage of trifocal lenses is that in some cases, they offer a broader viewing area for near and intermediate-distance applications like reading and using the computer.



How do drivers wear glasses or sunglasses better?

We should pay attention to the dim light at night on the impact of vision, At night, for the people who wear glasses, it is best not to drive, but to prevent fatigued driving. If you need to drive, you must choose clear and appropriate optical glasses. When the light is strong in the field, it is advocated to wear light-colored sunglasses with appropriate degrees to ensure driving safety.

Shaded sunglasses, coated with reflective material, block out light from above and increase horizontal and lower light, which makes it easier to see the platform. Clip-on sunglasses are suitable for people who wear glasses themselves. You can go straight with a pair of myopic sunglasses for a higher price.
