In the summer, when the sun is shining, many friends who drive will choose to wear sunglasses. Of course, myopia can also wear sunglasses. So how do you choose sunglasses for myopia? Is it a polarized sunglasses or a myopic sunglasses? Here is how to choose sunglasses when driving in summer.
Common Mistakes: The darker the lens, the better.
Many friends think that the deeper the color of the lens, the better the effect of blocking the sunlight. This is wrong.
The color of the sunglasses lens can delay the time the eye sends the image to the brain. This visual delay causes the speed perception to be distorted, causing the driver wearing the sunglasses to make a wrong judgment.
When the car travels at a speed of 80 kilometers per hour, the deeper sunglasses will delay the driver's reaction time by 100 milliseconds, thus increasing the emergency braking distance of 2.2 meters.
Selection method: Do not choose the lens color is too dark, that is, use dark black sunglasses less.
Choose polarized sunglasses as much as possible. Polarized sunglasses can reduce glare, effectively eliminate and filter out scattered light in the beam, make the field of vision clear and natural, and can also reduce the glare, anti-fatigue, no obstruction of sight, UV protection and other functions.
