視網膜撕裂 — 激光修補 - https://thestandnews.com/cosmos/%E8%A6%96%E7%B6%B2%E8%86%9C%E6%92%95%E8%A3%82-%E6%BF%80%E5%85%89%E4%BF%AE%E8%A3%9C/

The reality is that, unless you have a degenerative problem that needs to be treated by an ophthalmologist, there is no reason to try to naturally improve your eyesight, and there is not much any lens can do in this regard (unless we’re talking about children). You can put in the effort, but it is unlikely to help. Think about whether you really need to see any better than you currently do, considering you have glasses to fix the issue.
Progressive lenses can help you switch more comfortably from far to close distance. Your eyesight won’t magically improve, but that should never be your expectation when choosing glasses. - https://www.zmescience.com/science/are-progressives-lenses-good-for-your-eyes/
