Is glass or acrylic better for magnifying glass?
Acrylic magnifying glasses are also easier to handle, and they don’t run the risk of breaking nearly as quickly as a glass magnifier would break from a simple drop or mishandling mistake. Lastly, acyclic lenses are designed to be 100% scratch resistant.
