Can you get prescription glasses for night driving?
It is recommended to choose prescription night driving glasses with an anti-reflective coating.When you're driving at night, you'll encounter several bright light sources, including the car's headlights, taillights, and street lights. These light sources can be a distraction for any driver, but especially for those with eye problems. The light reflected from these light sources can cause these drivers to temporarily lose sight of the road, which can lead to many unfortunate situations. As a result, the anti-reflective coating protects your eyes from nighttime brightness and daytime UV damage. The coating on the glass prevents the reflection of these light sources, allowing you to better focus on what's happening in front of your car. Meanwhile, prescription glasses with an anti-reflective coating can reduce glare and improve vision. Whatever prescription glasses you choose for night driving, make sure they have an anti-reflective coating.

Does blue light cause damage to the eyes?
Businesses often associate blue light with mobile phones and computers that everyone frequently touches. There are also many terrible explanations about blue light on the Internet, ranging from causing damage to the eyes to causing cancer. Therefore, in recent years, mass media and academic circles have caused heated discussions about the possible impact of blue light on eye health.
It is believed that the reason why blue light harms the eyes is that blue light is not like ultraviolet light which is absorbed by the cornea and lens so that it cannot reach the retina. Blue light can reach the retina through the refractive medium of the eye, and over time it will cause the aging and functional degradation of the retina. But in fact, the eyes have many protection mechanisms in the process of evolution, such as squinting, pupil contraction, lutein contained in the macula of the retina, the anti-oxidant repair mechanism of the retina, etc., which can protect our eyes from the damage of blue light. Also, after scientific testing, the blue light emitted by electronic products is a few percent of the intensity of blue light in natural light, which means that as long as the electronic products are not used continuously every day (for example, more than 8 hours a day), blue light will not be causes obvious damage to the eyes.
