Beschreibung
Zusammenfassung:	The invention relates to an ophthalmic device (1) which includes an electrochromic cell (3) comprising at least two transparent layers (4, 5) having curved inner surfaces (4a, 5a) and defining therebetween a closed recess (6) filled with an electrochromic composition (7), the recess (6) being defined peripherally by a sealing gasket (11) made from an adhesive material (20), the sealing gasket (11)being suitable for keeping the two transparent layers (4, 5) assembled together. 本发明涉及种包括电致变色单元(3)的眼科装置(1)，所述电致变色单元包括至少两个透明层(4，5)，所述透明层具有弯曲的内面(4a，5a)并且在其之间限定了由电致变色组合物(7)填充的密封空腔(6)，所述空腔(6)在周边被由粘合剂材料(20)制成的密封件(11)限定，所述密封件(11)适合于支撑彼此组装在起的所述两个透明层(4，5)。
