Publication number: 20220283450Abstract: An ophthalmic set for myopia progression control includes a first component suitable for varying an amount of light that has wavelength values included in a modulation spectral range and enters an eye of a user. It further includes a control unit configured for controlling the first component so that light with wavelength values in the modulation spectral range enters the user's eye with varied intensity during daytime. The first component may include light sources and/or spectral filters, in particular arranged so as to be fitted on the user's face during appropriate durations. Preferably, light with wavelength values included between 360 nm and 520 nm, or between 440 nm and 520 nm, is increased in the morning and reduced in the evening.Type: ApplicationFiled: March 4, 2022Publication date: September 8, 2022Inventors: Konogan BARANTON, Coralie BARRAU, Matthieu GUILLOT, Thierry VILLETTE

Publication number: 20220283451Abstract: An ophthalmic set for myopia progression control comprises spectral filtering means arranged for being effective on light that enters a user's eye. The spectral filtering means selectively reduce blue-green light intensity, and possibly also amber light intensity. Preferably, said spectral filtering means are combined with wavefront modifying means within the ophthalmic set for increased efficiency in slowing-down myopia progression for the user. In possible embodiments, the spectral filtering means and wavefront modifying means are combined in spectacle lenses (1, 2), and the wavefront modifying means are comprised of microlenses (21) or light-diffusing elements.Type: ApplicationFiled: March 8, 2022Publication date: September 8, 2022Inventors: Konogan BARANTON, Thierry VILLETTE, Coralie BARRAU, Matthieu GUILLOT
