“A hermaphrodite is the same at a distance of three meters, and humans and animals are indistinguishable from a distance of five meters.” I think this sentence is perfect to describe patients with severe myopia. People with normal vision will never understand the pain of Gaussian blur in our eyes.
If you suffer from myopia when you are young, you will not suffer from presbyopia when you are old. I dare say that there are definitely not a few people who have this idea! If you think about it, people with myopia will see blurred distances but clear nearsighted people, and people with presbyopia will see blurred nearsights but clear farsightednesses. So if both are good, wouldn’t they cancel each other out?
However, reality always likes to send me a song "When I Wake Up" when I am whimsical. In fact, saying that you won't get presbyopia if you are myopic is as outrageous as saying that you won't get fever in the Arctic. Because their pathogenesis is completely different. Myopia is a refractive error caused by the elongation of the axial length of the eye, while presbyopia is a decrease in refractive power caused by the aging of the lens and ciliary muscle.
That is to say, myopia and presbyopia can be combined. The consequence is that you can't see clearly near or far. Since he is so cruel, we can only count on the power of technology. No, the Japanese company Mitsui Chemicals recently launched TouchFocus, an electronic zoom glasses.
It is said that after wearing it, you can see clearly from far to near, and it has captured the hearts of many uncles and aunts in Japan.
The principle is to add a liquid crystal display area under the lens. After turning it on, it can be transformed into short-focus glasses to view nearby objects. However, this display area is turned off by default and can only be activated by touching the switch on the temples with your finger.

Just talk and don’t practice the fake moves. Let’s see its actual use effect. When you want to look at the chart on your hand, touch the mirror. The legs will open the LCD display area, making the field of view instantly clear. When you want to see the PPT in the distance, touch it again and it will return to the normal glasses mode. The chart will be blurred, but the PPT can be seen more clearly.
These two modes can be freely switched according to needs in daily life. You can see the steps clearly when walking up the stairs~

You don’t even need a magnifying glass when reading
In fact, this kind of electronic zoom Glasses were made as early as 2011, when they were called emPower.
Functionally speaking, it is more powerful than the current TouchFocus. You don’t even have to press the switch manually, you can zoom automatically through the micro acceleration sensor! At that time, its appearance was claimed to be able to change the glasses market. Unfortunately, Fengguang went bankrupt later due to shipment issues.
TouchFocus glasses are the first product to commercialize this concept, but they are not cheap, with a pair of 250,000 yen, or about 15,300 yuan. Having said all that, you should test whether you need this pair of glasses first.
