No.21s eye is a special eye, built for enhanced visual acuity and data gathering allowing her to track prey more effectively. Essentially it does everyone having an extra eye in the form of a sensory robot (my nigga chibiko) does, except better. Canons eyes look like that for no reason that we know, but shes a construct thats focused on forests and stuff maybe she needs something similar.
