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 can I measure the frame size?
Use a ruler to measure the glasses you used to wear comfortably and record the width of the frame and the total width in front of the frame. And compared with the frame width of the selected frame and the total front width of the frame. Frame width size difference of one or two millimeters does not matter, and the total front width of four millimeters does not matter. You can use a ruler to measure the approximate distance between the temples. Usually, the width of the inner side of the frame is the same as the temple value or about 3MM larger than the temple value.
Choose the frame according to the skin color
Generally, people with lighter skin tones are best to choose lighter-colored frames. For darker-skinned people, choose frames with darker colors. For example, people with white skin can choose the frame of soft pink, tortoise color, or golden silver, while people with darker skin color can choose red, black, or tortoise color.
How to do with it?
Wash your glasses once a week to avoid future accumulation. Remove the green goo with a soft cloth, a cotton swab, some mild dishwashing liquid, alcohol, and a soft-bristled toothbrush. Ultrasonic cleaning machines can remove dirt and green mud because vibration can do with micro-mud. This device is available in most optician stores, so you can have your glasses cleaned there. Just like anything we use, glasses need to be replaced. It is recommended that you replace the nasal pad with a new one every 6 months to keep it sanitary.
Do blue light glasses actually block blue light?
Anti-blue light glasses are still popular on the market. This kind of glasses is said to be 'anti-radiation and anti-blue light', but this kind of hot-selling anti-blue glasses has many problems. At present, such anti-blue glasses mainly block or absorb blue light through special materials, but there are two misunderstandings in its blue light protection. One is that the protection is not preventable, and the other is that the color cast caused by the wrong protection makes visual fatigue aggravated. Studies have shown that our eyes are the most intolerant of blue light in the 400nm to 440nm band. Therefore, current manufacturers mainly block blue light in this band when producing anti-blue glasses. But the electronic products that we often come into contact with nowadays produce blue light between 450 nanometers and 490 nanometers, and anti-blue glasses have almost no protection in this wavelength. Generally speaking, the blocking rate of anti-blue glasses is 20% to 30%, but now the blocking rate of anti-blue glasses on the market basically reaches 80% to 90%. This high blocking rate can also easily cause a color shift. , It is easier to make the eyes tired.
