Looking at the structure of the human eye, the 'conjunctiva' within the eyeball prevents anything from going behind the eye. However, in rare cases, RGP (Rigid Gas Permeable) hard lenses may accidentally go behind the eye. The sharp edge of hard lenses can tear the conjunctiva, causing the lens to slip behind, leading to the formation of cysts or drooping eyelids.
On the other hand, soft lenses, due to their soft material, cannot breach the conjunctiva and go behind the eye. If you feel like the lens has gone to the back, it is more likely lodged between the eye and eyelid or stuck inside the eyelid. Fantasy-icon exclusively sells soft lenses, exporting to Europe and South America, offering internationally certified products that meet quality standards.
