Six inventions. One granted national patent and five pending applications.

A dual-band spectral filtration system that independently attenuates two tuned wavelength bands relevant to photophobic and circadian load while preserving photopic luminance and colour balance.

An ophthalmic lens that enhances chromatic contrast perception by selectively shaping transmission across the visible spectrum to support colour discrimination and visual clarity.

An absorptive ophthalmic lens formulated with a multi-component chromophore system that attenuates selected evening wavelengths associated with melatonin suppression while maintaining daytime visual function.

An optical lens system in which different spectral bands exhibit independent temporal activation and relaxation kinetics, enabling a spectrally differential photochromic response.

A system and method for assessing biological light exposure adaptively, characterising the circadian relevance of incident light for ophthalmic and environmental applications.

A passive adaptive ophthalmic lens that employs state-dependent optical gating between layers to modulate transmission without active electronic control.
