Abstract
Embodiments of a modulable absorption light adjustable lens (MALAL) comprise a light adjustable lens that is capable of changing its optical properties upon an adjusting irradiation, including a photo-modifiable material; and a modulable absorption front protection layer, including a modulable absorption compound whose absorption properties can be modulated with a modulating stimulus. Other embodiments include a method of adjusting an optical property of a modulable absorption light adjustable lens, the method comprising: reducing an absorption of a modulable absorption compound of a modulable absorption front protection layer of the MALAL by a modulating stimulus, the MALAL having been previously implanted into an eye; and changing an optical property of a light adjustable lens of the MALAL by applying an adjusting irradiation.
