A projection apparatus includes a light source module, a first color wheel, a second color wheel and a control unit. 010 Scm or more, methanol diffusion coefficient of 4\xd710\u22127 cm2s of less, tensile strength of 40 MPa or more, and pressure strength of 500 kgfcm2 or more. The protocol interface between the AR and AC includes a trusted network transmission interface and IF-TNACCS interface between TNAC client and TNAC server. The housings are positioned in a shielding shell when fully terminated to fully shield the connector assembly. The movement includes three components: a first component, z1 that is dependent upon the shape of the contact lens, a second component, z2 that compensates for refraction at the surfaces of the contact lens, and a third component, z3, that compensates for refraction caused by the anatomical configuration of the cornea.
