When you age, your body gets older and parts begin to wear out. This cannot be disputed for eyes. Over time the eye become inflexible, it will be harder to read fine print, your lens will cloud over and will need to be replaced. This is called cataract surgery.
I have noticed a lot of different types of discrimination in China. Sometimes it is discrimination against foreigners, but usually against fellow Chinese. There is the rural/urban divide, men vs women, Xinjiang vs the CCP, etc. But sometimes there is discrimination based on age. The most predominant is against women over 30, the so called “leftover women”, which is a very derogatory term. This time it is age discrimination in the IT industry.
