Background

At present, a light feeding instrument is increasingly used in the myopia physiotherapy process, and the specific principle is that a laser light source in the light feeding instrument is used for emitting red light of a specific wave band sensitive to eyes and irradiating the eyes for a certain time, and the photon biological stimulation effect is used for improving fundus microcirculation, so that the eye physiotherapy effect is realized. In addition, the most sensitive place of retinal sensitization is the fovea of the retina, which is a shallow funnel-like small depression of about 2mm diameter in the posterior pole of the retina, also known as the macular fovea. The retina around the fovea becomes slightly thicker, while the fovea retina is thinner, where only the vitamin cells are present, so the fovea is the region where retinal vision is most powerful. The sensitivity and resolution of vision from the fovea to the peripheral portions of the retina gradually diminish. Therefore, attention is paid to the protection of the foveal area during the light physiotherapy.

However, the existing light feeding instrument generally irradiates light rays for physiotherapy emitted by a light source onto eyes of a user, and when the light spot center irradiates the central concave position, the light rays are easily irradiated into damage of the central concave of the retina, so that medical accidents occur.

Example 1

As shown in fig. 1, this embodiment provides a nursing light instrument with physiotherapy protection function, including casing 1, casing 1 is inside to correspond eyes and sets up two light path passageway 2 side by side, the axis of light path passageway 2 extends along the sight direction, the one end that light path passageway 2 kept away from the eyes is equipped with light source module 3, light path passageway 2 is close to eye one end and is equipped with convex lens 7, be equipped with lens structure 5 between light source module 3 and the convex lens 7, lens structure 5 arranges light path passageway 2 inboard in, wherein, lens structure 5 is used for changing the light path so that the facula central energy that reaches the retina can be reduced, the central energy of light spot is higher when avoiding light to shine on eye 8.

In this embodiment, the convex lens 7 is used for adjusting the path of light, where the distance between the virtual image presented by the light source module 3 through the convex lens 7 and the eye 8 is greater than the distance between the light source module 3 and the eye 8, so that the irradiation area of the light source module 3 is increased, that is, a relatively large part of the area on the eye 8 can be still irradiated while the short distance between the light source module 3 and the eye 8 is maintained, and by setting the convex lens 7, the distance between the light source module 3 and the eye 8 is shortened, the thickness of the light-feeding instrument is shortened, and portability is improved under the condition that the irradiation range of the light source module 3 on the eye 8 is unchanged.

In this embodiment, as shown in fig. 3, the lens structure 5 is a circular structure as a whole, specifically, a central area of the circular structure is a filtering area 51, and the filtering area 51 can partially filter the light passing through the area, so as to reduce the energy intensity of the light passing through the area, and avoid the irradiation damage of the light spot center to the fovea.

In this embodiment, because the energy change of the light spot center is a curve change, the outward light filtering rate of the light filtering area 51 from the center of the circle gradually decreases, so as to ensure that the energy of the light transmitted through the area is approximate, that is, ensure that the energy of the light spot transmitted through the light filtering area 51 is relatively uniform or the energy of the light spot center is smaller than the surrounding energy, so that the light spot irradiated onto the retina has a corresponding light spot center with a concave retina, and the concave retina can be protected by the reduced energy of the light spot center, thereby avoiding damage to the concave retina.

In addition, the annular region located at the outer circumference of the light filtering region 51 is a light transmitting region 52 (i.e. a non-light filtering region), and the light filtering region 51 overlaps with the geometric center of the light transmitting region 52, and the light transmitting region 52 is not provided with a light filtering layer, so that no light filtering effect is provided, and light can directly pass through the region, so that the light spot energy transmitted through the light filtering region 51 and the light transmitting region 52 is approximate, and the influence on the physiotherapy effect is avoided.

In this embodiment, the center of the lens structure 5 is a circular filtering area 51, a transparent area is formed around the filtering area 51, and the filtering area 51 corresponds to the central position of the light spot, so as to reduce the energy of the central light, so that the energy of the central light tends to be consistent with the energy of the surrounding or the energy of the central light spot is smaller than the energy of the surrounding, and further, when the central light spot irradiates the fovea, the fovea is not damaged due to the too high energy, and meanwhile, the light transmitting area 52 also does not reduce the energy of the periphery of the fovea, so as to influence the physiotherapy effect.

In this embodiment, the annular region around the concave region is a planar lens region or a convex lens region.

When the non-astigmatic area is the condensation area of annular structure, the cross section of the condensation area is convex lens structure, namely when the annular area is convex lens area, light can be refracted, and according to the change of curvature, the light can be refracted to the axis in different degrees, the effect of condensation is achieved, the light at the edge is inwards adjusted, the energy of the irradiation position on the corresponding light spot tends to be similar or the energy of the light spot center is smaller than the surrounding energy, the light spot irradiated on the retina is enabled to be the central concave of the retina, the energy reduction of the light spot center can be beneficial to protecting the central concave of the retina, and the damage of the central concave of the retina is avoided.

When the non-astigmatism area is a flat light-transmitting area with an annular structure, the cross section of the flat light-transmitting area is a plane lens structure, namely, when the annular area is a plane lens area, light rays directly pass through the area, the light path is not obviously changed, and the energy corresponding to the irradiation position on the light spot is not changed.

In this embodiment, the problem of reducing the energy concentration in the central area is achieved, and the loss of light energy can be avoided to the greatest extent. The center of the lens structure is a light scattering area, the periphery of the lens structure is a light condensing or flattening mirror surface, the light scattering area corresponds to the position of the center of a light spot and is used for scattering light rays of the center of the light spot to the periphery, the energy of the light rays of the center is reduced, the energy of the light spot tends to be similar or the energy of the center of the light spot is smaller than the energy of the periphery, and when the energy of the light spot tends to be similar or the energy of the center of the light spot is smaller than the energy of the periphery, the energy of the retinal fovea corresponding to the center of the light spot is relatively lower, so that the damage of the fovea is avoided.
