The present disclosure provides a contact lens comprising a first colourant which is a blue-blocking colourant having an absorption maximum (λ
max
) in the range of from 415 nm to 455 nm and a second colourant, wherein the second colourant is a polymerizable dye having an absorption maximum (λ
max
) in the range of from 470 nm to 600 nm, and optionally also comprising a third colourant which is a colourant having an absorption maximum in the range of from greater than 600 nm to 800 nm. A method of making the lens is also provided.

(EN) This invention relates to radio-derivatized polymers and a method of producing them by contacting non-polymerizable conjugands with radiolysable polymers in the presence of irradiation. The resulting radio-derivatized polymers can be further linked with ligands of organic or inorganic nature to immobilize such ligands.(FR) Polymères radio-transformés en dérivés et leur procédé de production, consistant à mettre des conjugands non polymérisables en contact avec des polymères radiolysables en présence d'une irradiation. On peut en outre lier les polymères radio-transformés en composés ainsi obtenus, à des ligands de nature organique ou inorganique afin d'immobiliser lesdits ligands.
