Patients with myopia or astigmatism,
However, the human eye is constantly changing, so it is generally recommended to need an eye examination every six months.
If the reading of the eye is different from that of the glasses, you will need to spend money to change the lenses for the glasses.
However, it costs a lot of money to change lenses every time, and recently scientists in the United States have developed a pair of glasses made of liquid lenses.
Can perform "autofocus" for the human bodyAfter wearing this pair of glasses,
Everything can be made clear, and you will never need to change your glasses again.
These glasses were already on display at CES 2017 and use liquid lenses.
In the middle of the lens, there is a layer of glycerin wrapped in a transparent transparent film that simulates the crystals on the human eye.
There are 3 drives around the lens to change the refractive index of the lens.
Controls the shape of the crystal to adjust the focus.
At the same time, it is equipped with an infrared distance sensor, which can automatically detect the distance between the object and the lens.
Change the refractive index by automatically adjusting the shape of the lens.
At the same time, glasses can be calibrated for different vision needs through the mobile app.
This provides a long-lasting autofocus glasses for patients with nearsightedness, farsightedness and astigmatism.
However, the current technology is still in its infancy, so the volume is relatively bulky.
And the price is relatively high.
The development team intends to develop it to reduce the volume and at the same time hope to be able to mass produce within 3 years.
It sells for around $500 to $1000.
