Is it harmful to our eyes ？

[rimless eyeglasses]

I saw a kind of small aperture eyeglasses at the website of many optical online shops accidentally, the retailer said that it can correct vision problem and presbyopia issue, is it really true? Is it harmful to our eyes if we wear them for a long time? Who has used this kind of eyeglasses or known about it before? If you do, please tell me the felling that you’re trying.
