What kind of glasses can prevent high beams?

Currently, there is no type of lens that can block direct light, as blocking it would render the glasses opaque, making it impossible for the driver to see objects outside. More details are as follows: 1. As for the so-called 'anti-glare glasses' available on the market, they cannot prevent high beams. These glasses can only reduce the glare around direct light, minimizing visual interference, but the effect is limited because high beams are not glare. 2. When driving at night and encountering oncoming vehicles, it is essential not to use high beams, as this is highly uncivilized behavior. You must switch back to low beams in advance when meeting another vehicle; otherwise, it will impair the oncoming driver's vision and pose significant safety risks.
As a long-distance driver, I've found that professional polarized driving glasses are the most effective against high beams. These lenses can filter out horizontally polarized light from intense glare, reducing scattered strong light like high beams by more than two-thirds. Light gray or amber lens colors are the best choices, as dark tints can actually impair nighttime road sign visibility. Opt for high-transparency resin material to avoid the fragility issues of glass. Having worn these glasses for three to four years, my eyes don't experience sudden blackout during nighttime encounters with oncoming vehicles, and I can still clearly see reflective road edge markers. Many brands now offer driving glasses with blue light filtering coatings, which are also practical for people spending long hours facing electronic screens.
I usually enjoy researching automotive accessories, and anti-glare glasses mainly fall into two categories: regular driving glasses and smart photochromic lenses. The regular ones are polarized sunglasses, and when driving, it's best to choose frameless designs to avoid obstructing your view. Smart photochromic lenses are more high-tech, instantly darkening when exposed to strong light, with a reaction time of about 0.5 seconds. If you frequently drive on mountain roads or highways, it's recommended to purchase models with side anti-glare designs, which can also filter out strong light from your peripheral vision. Prices range from tens to thousands, with the key factor being whether the lenses can truly filter over 96% of UV rays.
