FIELD: medicinal polymers. SUBSTANCE: invention relates to an optic facilities, in particular ophthalmologic lens, lens blanc or preliminarily shaped lens blanc, composed of thermoplastic material depicted by following formula: , in which n=20- 200; R represents hydrogen atom,
, or
; Ar represents
; and X is constituted by
(10-100 mol %) and
(0-90% mol %) or
(0-90% mol %). EFFECT: enabled manufacture of optically transparent optic facilities having reduced-thickness borders due to high refraction index values. 15 cl, 2 ex
