Anti Blue Glasses
The difference between anti-blue light lenses and ordinary lenses
When matching glasses in an optical shop, many people choose to wear anti-blue light glasses because they often look at mobile phones and computers. Ordinary people can distinguish between anti-blue light lenses and ordinary lenses by the following methods:
1. Although both anti-blue light lenses and ordinary lenses are yellow-green films, ordinary lenses have a yellowing feeling under the reflection of light; while anti-blue light lenses are light blue under light, which can reflect blue light. , which is their biggest difference.
2. The optical shop has a professional anti-blue light pen, which can test the lenses.
Blue light is an important part of visible light. There is no separate white light in nature, but blue light is mixed with green light and yellow light to present white light. Green light and yellow light have less energy and less irritation to the eyes. Blue light has a short wavelength and high energy, and can directly penetrate the crystal and reach the retina.
Many businesses publicize how harmful the blue light emitted by computers and mobile phones is to the eyes. In fact, the most blue light in life is sunlight. If the health of the eyes is pinned on anti-blue light glasses, it is better to use less eyes and develop healthy living habits. . Here are some ways to keep your eyes healthy:
1. When looking at electronic devices, observe an object at least 6 meters away every 20 minutes for at least 20 seconds.
2. Within the acceptable range, enlarge the font appropriately to reduce eye fatigue.
3. For children with developing vision, it is important to limit the time and frequency of electronic products.
