The invention discloses a traditional Chinese medicine composition for treating perimenopausal dry eyes and a preparation method and application thereof, and relates to the technical field of traditional Chinese medicine formulas. The traditional Chinese medicine composition for treating the perimenopausal dry eye comprises herba epimedii, prepared rehmannia root, rhizoma anemarrhenae, cortex phellodendri, radix paeoniae alba, angelica sinensis, radix bupleuri, poria cocos and honey-fried licorice root. The traditional Chinese medicine composition for treating perimenopausal dry eye, namely the kidney-warming dry eye formula, has the functions of warming kidney, nourishing yin, soothing liver and strengthening spleen, can effectively improve perimenopausal symptoms such as dry eye, photophobia, asthenopia, foreign body sensation, burning sensation, soreness and weakness of waist and knees, dysphoria, irritability, hot sweating, insomnia, amnesia and the like of patients with perimenopausal dry eye, improves the estrogen level, and has the efficacy of treating perimenopausal dry eye. The ocular surface inflammatory response is inhibited, and the tear film stability is improved.

Disclosed is an apparatus and method for combating light sensitivity, or photophobia, for people with low vision. Both the apparatus and method filter particular wavelengths of light associated with photophobia. This filtering is achieved while maintaining a luminance that is acceptable to the user and that maintains contrast. The apparatus of the disclosure is a mechanical filter that can be applied over an electronic screen. The method utilizes software and a filtering module associated with either the CPU or GPU of a computer. The filtering module processes a video signal by eliminating certain targeted wavelengths of light.

To provide methods, systems and apparatus for reducing frequency and / or severity of photophobic responses or for modulating circadian cycles.SOLUTION: An optical filter may reduce the frequency and / or severity of photophobic responses or modulate circadian cycles by controlling light exposure of cells in a human eye in specific wavelengths, such as 480 nm and 590 nm, and a visual spectral response of the human eye. The optical filter may disrupt the isomerization of melanopsin in the human eye thereby reducing the availability of an active isoform, whereas the attenuation of light weighted across the action potential spectrum of the active isoform attenuates the phototransduction cascade leading to photophobic responses. In one embodiment, an optical filter may be configured to transmit less than a first amount of light at specific wavelengths, and to transmit more than a second amount of light weighted across the visual spectral response.SELECTED DRAWING: Figure 6

Keratoconjunctivitis sicca is a general term of a plurality of diseases which are accompanied by eye discomfort and (or) ocular surface tissue lesion characteristics and are caused by tear quality or quantity abnormality or dynamic abnormality caused by any reason, and belongs to the field of chronic keratoconjunctivitis in western medicine. The common symptoms comprise eye dryness, easy fatigue, eye itching, foreign body sensation, burning pain, secretion viscosity, wind afraid, photophobia, lacrimation and external stimulation sensitivity; the two eyes of a patient with serious diseases in the later stage are red and swollen, hyperemia and keratinization, corneal epithelium exfoliation and filament adhesion exist, keratoconjunctival lesion can be caused if the patient is injured for a long time, and the continuous development of the keratoconjunctival lesion possibly causes irreversible influence on vision. The traditional Chinese medicine composition is characterized by being prepared from the following raw material medicines in parts by mass: 100 to 1000 parts of radix rehmanniae, 100 to 1000 parts of radix ophiopogonis, 100 to 1000 parts of herba dendrobii, 100 to 1000 parts of bulbus lilii, 100 to 1000 parts of radix polygonati officinalis and 200 to 500 parts of flos chrysanthemi. Corresponding auxiliary materials can also be added into the traditional Chinese medicine composition to prepare clinically common tablets, granules and oral dosage forms.

Disclosed herein are methods of treating or preventing headaches (e.g., migraines) and / or photophobia in a subject comprising administering a pharmaceutical composition comprising one or more therapeutic agents selected from a triptan, a beta blocker, an alpha agonist, and a CORP antagonist.

A lighting device that provides a green-enriched white light. The lighting device includes one or more light sources that collectively produce light with wavelengths ranging from violet light through red light. A normalized intensity of wavelengths in a green light range of the produced light is greater than a normalized intensity of wavelengths in a blue light range of the produced light.

The invention belongs to the technical field of medical instruments, and provides a retinopathy examination device. A retinopathy examination apparatus according to the present invention comprises: an examination subject for examining retinopathy; the fixed rack is arranged at one end of the examination main body and is used for supporting and fixing the head of a patient to be examined; and the shading assembly is rotationally mounted on the inspection main body, is propped against the fixed rack and is used for shading. In conclusion, the retinopathy examination device is reasonable in design and easy to operate, the fixing effect and light shielding can be effectively achieved, photophobia of patients is reduced, and efficient and accurate examination results are achieved for diabetic patients; therefore, the device is suitable for industrial popularization.

The invention discloses a photoetching ultrastructure multifunctional lens for preventing and delaying myopia, which comprises a lens main body, and a functional area is arranged in the lens main body. Compared with the prior art, the ultra-micro lens has the advantages that the ultra-micro lens forms a dense negative out-of-focus signal interference area, when eyes rotate, light passing through the area can generate irregular dynamic changes in different states of convergence, divergence and the like, meanwhile, the light is diffused at gap composite points of the photoetching ultra-micro lens, and the light intensity is improved. By means of the comprehensive design, the intensity of the negative defocus signals reaching the retina can be weakened to the maximum extent, the brain is prevented from receiving the negative defocus signals possibly accelerating myopia development, and then the effect that myopia occurrence and development are delayed in a nearly non-inductive mode is achieved. For the photophobia phenomenon occurring when low-concentration atropine is used for preventing and controlling myopia, a color-changing film layer can be additionally arranged to adjust the brightness of light rays entering eyes so as to relieve symptoms.
