The paper frame has no comfortable wearing experience at all, whoever uses it knows.2. Everything else you can see is hard ,and the gles have very thin legs,which actually torments your cheeks when wearing them.3. AoHeng's TR90 high elastic frame,ultra wide gles legs,and breathable surround design provide us with the best wearing and viewing experience. Users wearing prescription gles should not choose frame gles.Because after wearing two gles, as the prescription gles that fit the nose and eyes are your own, the nose rest and frame of the large frame gles will stay away from your nose and eyes This will make you feel a lot of shadow interference in the middle and surrounding of your line of sight,and your nose and cheeks cannot withstand the long-term pressure of two gles.Please verify on your own.
