But try not to do myopia surgery, because the surgery itself is to change the projection on the retina by reducing the thickness of the lens to achieve the purpose of treating myopia. The higher the degree of myopia, the greater the thickness that needs to be changed.
In the case of high-speed movement or impact (such as many amusement facilities: roller coasters, pirate ships, diving), if the lens thickness is reduced, the ability to withstand intraocular pressure will be reduced, resulting in lens rupture, and in the most serious case, eyes will be blind (this is not unprecedented, there are many others), so we must be cautious.
