摘要： An ophthalmic lens includes: a transparent ophthalmic lens substrate made of organic glass; an adhesive layer covering at least one of the faces of the transparent substrate; a transparent film made of a thermoplastic polymer fixed to the transparent substrate via the adhesive layer; and an abrasion-resistant coating covering the transparent thermoplastic polymer film, characterized in that the ophthalmic lens has a minimum thickness at the centre of less than 2 mm, preferably less than 1.5 mm and even more preferably less than 1.2 mm. Two processes for manufacturing such a lens and the use of an adhesive multilayer film to improve the impact strength of such a lens are also described.
