Description

Ophthalmic kit for myopia progression control The present invention relates to an ophthalmic kit for myopia progression control. In this specification, the terms "myopia progression control", "myopia progression reduction" and "myopia progression reduction" are used with equivalent meaning. Background Myopia progression has been confirmed by a number of observations and has been well documented for years, although the cause of myopia progression is still under investigation. Myopia progression refers to the increase in myopia over time at a rate that was nearly absent before for a person. Children are the most affected group by myopia progression and thus solving this problem is a significant problem. Close work and lack of outdoor activity are considered to be causative of myopia progression, but the actual biological phenomena and mechanisms that lead to myopia progression remain at hypothetical levels. Several principles and methods have been proposed for controlling the progression of vision defects in a person's myopic eye, including those principles and methods now mentioned. One of these methods consists in adding, to an optical lens (spectacle lens or contact lens) for correcting the vision of a myopic eye, a plurality of optical elements having a spherical optical function, which focus incident light in front of the retina of the eye, and in addition, light passing through the optical lens without passing through the plurality of optical elements is focused on the retina, thereby allowing a wearer equipped with these optical lens or contact lens to have clear vision. Another method consists in adding to said optical lens for correcting myopia aspheres a plurality of optical elements having an optical function other than spherical. Yet another approach consists in adding diffusing or phase shifting elements to the optical lens for correcting myopia that reduce visual contrast when the optical lens is worn by a person. Still other methods implement progressive addition lenses that provide add power to compensate for accommodation lag, or bifocal prismatic lenses that produce both add power and prismatic effects. All of these methods are based on lenses designed to modify the wavefront of light entering the wearer's eye or modify the wavefront of a portion of this light. Additional methods are based on other principles, such as the administration of atropine to a subject, or the wearing of rigid contact lenses during the night to alter the shape of the cornea. There is still a need for new solutions to control the progression of myopia in the wearer. Recent studies have shown a role for red light in myopia progression control. The wavelength range of 600 nm (nanometers) to 750 nm, corresponding to red light, is believed to be effective for myopia progression control. Red light therapy has several limitations. In particular, red light typically performs illumination at a relatively high intensity, which can be annoying. In addition, some retinal damage due to red light therapy has been recently reported. It requires the use of specific devices with power dependency. In addition, different red light treatment regimens provide for the delivery of illumination at some time of the day. This can be cumbersome for the wearer and/or the wearer can forget to follow the appropriate regimen. In view of this situation, it is an object of the present invention to provide new devices for achieving myopia progression control that are more efficient than those known from the prior art. Another object of the invention is that such a device is easy to use for the user without any specific equipment depending on the electric power. Disclosure of Invention To meet at least one of these objects or other objects, a first aspect of the present invention proposes an ophthalmic kit for an eye of a user, the ophthalmic kit comprising: -a spectral filtering device configured to selectively emit light in at least one selected wavelength range of 600 nm to 750 nm in the visible spectrum, preferably in the range of 600 nm to 650 nm, when excited by ambient light, thereby allowing the retina of the wearer's eye to be exposed to light in said at least one selected wavelength range; A wavefront modifying means adapted to modify the wavefront of light entering the user's eye. In particular, the ophthalmic kit is for myopia progression control of a user's eye, and comprises: -a spectral filtering device configured to selectively emit light in at least one selected wavelength range of 600 nm to 750 nm in the visible spectrum, preferably in the range of 600 nm to 650 nm, when excited by ambient light, thereby allowing the retina of the wearer's eye to be exposed to light in said at least one selected wavelength range, whereby the spectral filtering device is efficient for slowing down the progression of myopia of the user; a wavefront modifying means adapted to modify the wavefront of light entering the user's eye to slow the progression
