Difference Between Driving Glasses And Night Vision Goggles
The special effect of polarized glasses is to eliminate and filter the scattered light in the beam of light effectively so that the light can be put into the visual image of glasses with the right track, and the field of vision is clear and natural. The effect of night vision goggles is that they allow the wearer to observe the surroundings at night without being affected by light. For example, aviation accidents can be greatly reduced through the use of navigation winches equipped with forward-looking infrared cameras on aircraft and by requiring pilots to wear goggles fitted with night vision goggles.
How to Clean Glasses
To clean glasses by yourself, you need to be careful and use the correct way to avoid some damage to the glasses such as scratches, etc. So, follow the below steps to clean glasses lens.
1. Before cleaning the eyeglasses, you need to wash and dry your hands first. You can use the soap to wash your hands dry them.
2. Rinse your glasses under a gentle stream of tap water. This way will remove dust and other debris and avoid causing scratches on your lenses. But one thing you need to pay attention to. Please do not use hot water since it can destroy some eyeglasses lens coatings.
3. Use a small drop of lotion-free dishwashing liquid to each lens. You can only use lotion-free brands.
4. Then gently rub both sides of the lenses and all parts of the frame. Make sure to clean every part of the eyeglasses.
5. Rinse both sides of the lenses and the frame. Make sure to remove all traces of the soap. Otherwise, it will cause the lenses to be smeared when you dry them.
6. Shake youreyeglasses to get rid of the water on your lenses gently and inspect the glasses carefully to make sure they are clean.

As for how to clean glasses, you can follow the above steps. But when cleaning your glasses, you should be careful enough. When cleaning your glasses, something you can’t do. In the following section, we will list some of them.
The Benefits of Anti-Reflective Coating
After knowing some basic information about anti-reflective coating, you need to know the benefits of anti-reflective glasses.
Anti-reflective glasses enable more light to pass through your lenses to optimize visual acuity with fewer distractions and the lenses look nearly invisible, which enhances your appearance by drawing more attention to your eyes and helping you make better eye contact with others.
In addition, the anti-reflective coating is especially beneficial when used on high-index lenses, which reflect more light than regular lenses. That is to say, the higher the index of refraction of the lens material, the more light that will be reflected from the surface of the lenses.
What’s more, the modern anti-reflective coatings can reduce the reflection of light from eyeglasses, allowing 99.5% of available light to pass through the lenses and enter the eye for good vision.
Because the anti-reflective coating can eliminate the reflections, it can also make your eyeglass lenses look nearly invisible so that people can see your eyes and facial expressions more clearly. Hence, anti-reflective glasses are more attractive and you can look your best in all lighting conditions.
Anti-reflective glasses have sharper vision with less glare when driving at night and greater comfort during prolonged computer use. So, you can find that anti-reflective glasses come with many benefits.
Color process of Contact lenses
Pigment printing process
It refers to the direct printing of pigments or patterns on the inside of the lens and then drying, which is the main production process of poor-quality chromatic contact lenses. Usually, small factories and small workshops use this method. The lens is being phased out because the pigment can easily seep out from the surface during wearing, causing discoloration and staining, and irritation to the eyes, which is a big risk.
Pigment build-in process
To be specific, the lens made by sandwich technology is a three-layer structure, the front and rear are colorless transparent layers, and the middle is a colored layer. After the processing of sandwich technology, the color layer is wrapped in the middle of the front and rear transparent layer, so that the pigment will not contact the eyes, which will not cause irritation and injury to the eyes. The downside of this process, however, is that the lenses are slightly thicker than normal contact lenses and are less oxygen-permeable, so they are not suitable for long-term wear.
The pressed film manufacturing process
This is a relatively new method of a similar sandwich process, and the color (pattern) is also made between the front and rear layers of the lens. But the color (pattern) is used to fill in the film process. During lens curing, the pigment seeps into the material instead of sticking to the surface. It feels as if the lens is covered in color within a single layer. This reduces the middle layer and makes the lens thinner, which naturally makes it more comfortable and permeable to oxygen.
The extraction of titanium
Nowadays, the commonly used extraction method is the reduction method of titanium tetrachloride. Compared to copper and zinc, although high in content, much more expensive. On the other hand, China is the country with the largest reserves of titanium, and a large number of steel mills with perennial overcapacity began to produce titanium, so the price of titanium fell year after year.
Semi-rimless glasses
With a half-frame design, the retro round glasses can be paired with a very thin metal frame, indicating the literary and elegant temperament. The frame with only the upper part of the lenses circle covering the lens integrates lightness and steadiness, highlighting the sense of fashion, not only shows the wisdom of business elites but the natural and free affinity. They are not heavy and relatively firm. It is suitable for different kinds of occasions. It can be used for business occasions, leisure occasions, and parties. It is stylish and composed, reflecting the quality of life.
Who needs computer glasses?
Blue light radiation from computer screens and so on usually only requires a piece of fiberglass to block, usually, we just use the anti-radiation glasses. Office white-collar workers often spend more than 8 hours a day working in front of a computer, and sometimes they spend their entertainment with a computer after going home. After long, the eye often can feel dry, sour bilge, ache, shed tears even, giddy. These are all related to the blue light stimulus emitted by the screen.
