The light transmittance of the photochromic material coated on the transparent screen may change when a light beam with a specific frequency range is irradiated on the photochromic material.
The optical transfer material comprises, for example, a photochromic material.
At least one of the thermoplastic materials is loaded with an active photochromic material.
At least one of the thermosetting materials is loaded with an active photochromic material.
An adjustable apodized lens aperture is described which is constructed using photochromic material.
The encapsulated photochromic dye having an increased fade rate.
A photochromic dye encapsulated by a dendritic polymer.
A photochromic film comprising a photochromic dye and a resin ingredient.
At least one of the layers is formed form a semi-solid polymerizable material, which comprises a reactive plasticizer and, optionally, a dead polymer, and, when used as the photochromic layer, further comprises a photochromic dye.
The articles of the inventions have at least two layers, at least one of which is loaded with a photochromic dye.
The photochromic compound is introduced into the photochromic host layer.
By using the photochromic curable composition, a photochromic cured body can be produced at low cost.
The mould is then filled with a photochromic article monomer composition and the monomer composition is subsequently cured to form a photochromic article substrate adhered to the photochromic host layer.
A photochromic segmented bifocal lens is produced with low photochromic fatigue and favorable %T values.
In producing a photochromic optical article, excellent adhesion between a base and a photochromic layer is attained.
A lens forming composition may include a first photochromic compound, a second photochromic compound and a light effector.
The present invention provides a method for manufacturing a photochromic article having a photochromic compound containing layer.
The invention also relates to a photochromic compound which is an adduct comprising a photochromic moiety and at least one pendent oligomer.
The photochromic layer does not release the photochromic compound and comes to have high substrate adhesion through a simple pretreatment.
In addition, since the photochromic coating layer has a good adhesion property, the photochromic multilayer body is excellent in durability.
The invention relates to a protective material comprising a carrier and at least one photochromic protein and/or a mutein of a photochromic protein.
The invention also relates to a photochromic composition and to the use of both the proton-translocating retinal proteins and the photochromic composition.
