Problems solved by technology

However, after the age of 35, most people's ability to adjust near-sightedness of the lens declines. As the age increases, the adjustment ability declines more and more, resulting in difficulties in reading and writing. A little bit of vision becomes blurred. In response to the above problems, reading glasses have appeared on the market, and the short-range vision within 30 cm of the reading glasses is very clear. If you want to see the distance (such as TV), you have to take off the glasses or simply lower your head. This is very troublesome, and the eyes are prone to fatigue, which aggravates the damage to the eyes.
