How do you identify the refractive index of lens?
In reality, this problem is often a problem for optical shop practitioners, sometimes they worry about whether the manufacturer's lenses match the nominal value of the refractive index. We need a prop, and that's the camber. Because it can be used to measure the strength of the lens. The luminosity of the lens can be calculated by subtracting the curvature of the inner and outer surfaces of the lens. The curvature difference of a lens of the same luminosity is inversely proportional to the refractive index, that is, a lens with a higher refractive index only needs a smaller curvature difference to achieve the same luminosity.
Understand blue light correctly.
Blue light has been shown to affect the body's circadian rhythms, with too much exposure to it late at night from gadgets such as mobile phones disrupting a person's ability to fall asleep. Therefore, it is recommended that people limit screen time two to three hours before bedtime and set their devices to night mode to reduce glare, relieve eye fatigue and minimize blue light at night. However, as we learn more about blue light, not all of it is bad for us. Blue light has been found to play an important role in maintaining health, such as regulating the secretion of hormones in living organisms. Blue light helps prevent reduced night vision and has been shown to benefit refractive development in adolescents and minors.
Drivers can wear night-vision goggles
Night-vision goggles can prevent headlights from blinding, add color saturation, and make the field of vision clearer. The normal night vision glasses are golden yellow in color and have a metal coating on the surface. This is the use of diamond high perspective reflection film technology, in the lens to add color and film layer, in order to maximize the brightness of the object being seen. It is to compensate for the light for driving, which makes light pass through your eye. It can increase the three-dimensional sense of objects, making the line of sight more clear, to avoid confusion caused by blinding headlights.

What diopters do rimless myopic glasses suit?
What diopters do rimless myopic glasses suit? It suits myopic diopters to be used by people with diopters of 600 or less than. Usually, the high diopters are 500, 600, or above, Rimless glasses can see the lens directly. The higher the diopters, the thicker the lens. Secondly, in rimless glasses, sunlight can shine in from the axis of the lens, resulting in a dispersion effect, which has a certain impact on viewing. Thirdly, rimless lenses, without the protection of the rim, are easy to be scratched and broken, so they need to be carefully protected and stored. So to sum up, people with the diopters of 500 or 600can choose myopia rimless glasses. But it is not recommended to choose rimless glasses for people with diopters of more than 800.
