To Study the Effects of Cordyceps Cicadae on Vision Care
MyopiaCordyceps cicadae is a traditional Asian herbal medicine with a variety of bioactive substances and curative effects similar to Cordyceps Cicadae, and it has been reported that anti-dry eye and eye protection ingredients can be extracted. With the advancement of civilization, the number of patients with high myopia is increasing year by year and suffers from complications of dry eye or other eye diseases. In this study, the subjects were provided with cicadae extract or placebo in a double-blind manner, tracked the degree of visual fatigue by regular questionnaires, and measured for visual acuity, axial length and diopter. The purpose of this study is to investigate the effect of cicadae extract on visual acuity and visual fatigue, and to evaluate its potential as a health food ingredient.
Low Concentration Atropine in the Prevention of Myopia in Children.
MyopiaProgressiveThis double-blind, randomized controlled clinical study is to evaluate the effectiveness and safety of low concentration atropine in preventing myopia in pre-myopia children, and to explore whether there is a dose effect relationship between different concentrations of atropine in preventing myopia.
To Evaluate the Effectiveness of New Specially Designed Fitlens Soft Lens.
MyopiaMyopia is a common disorder, affecting approximately one-third of the US population and over 90% of the population in some East Asian countries. High amounts of myopia are associated with an increased risk of sight-threatening problems, such as retinal detachment, choroidal degeneration, cataracts, and glaucoma. Slowing the progression of myopia could potentially benefit millions of children. To date, few strategies used for myopia control have proven to be effective. Currently, there are four categories of myopia control treatments: atropine eye drops, multifocal contact lenses, multifocal eyeglasses, and orthokeratology (ortho-k). None of these modalities are US Food and Drug Administration-approved to slow myopia progression, they have been shown to slow the progression by approximately 50% with few risks. Both orthokeratology and soft bifocal contact lenses have shown to slow myopia progression by slightly less than 50% in most studies. The Myolens progressive front soft contact lens is designed to slow down myopia progression in children, The Myolens lens is an aspheric design with a spherical back surface that provides clear vision, with a uniform round edge for excellent fit and optimum comfort. The Myolens-CN is designed with a central for the near optics, while the Myolens-CF with a central for the distance optics, which progressively changes to far area and within a defined optical zone area while considering the movement up-down of the lens on the cornea. The thought behind the design is that the center of the lens will not provide a full optical correction. In the suggested study, both Myolens modalities CN and CF will be investigated in compare to the current approved treatment - MiSight.

The Effectiveness and Safety of Low-intensity Single-wavelength Red Light in Controlling High Myopia...
Age 3 to 16 Years (Inclusive)Male or Female2 moreObjective: To study the effectiveness and safety of low-intensity single wavelength red light in controlling high myopia in children and adolescents. Methods: Subject population: Children aged 3-16 years who have high myopia. Sample size: 190 subjects were planned to be enrolled and assigned to the test or control group in a 1:1 ratio.
Effect of IOP Lowering on Progressive HM
High MyopiaGlaucoma1 moreCurrently, whether and when intraocular pressure (IOP) lowering medication should be used in progressive high myopia (HM) to control axial elongation is still a dilemma. Randomized trials are required to evaluate whether IOP lowering influences the growth of axial length in progressive HM eyes.
Software Refraction With Mobilerone Versus Retinoscopy
MyopiaMyopia2 moreSoftware refraction in the mobilerone for myopia and astigmatism is a novel medical device for myopia adults and elder children with or without astigmatism. And the investigators would like to test its accuracy and efficacy as well as safety.
The Effect and Safety of Different Doses of Atropine on Myopic Progression of Highly Myopic Children:...
High MyopiaObjective: to evaluate the efficacy of different concentrations of atropine eye drops in controlling the progression (diopter, axial length) of high myopia in young children, and to compare the compliance, adverse reaction and regression rate of different concentrations of atropine eye drops in myopia control. Intervention: Group 1 (0.01% atropine group), Group 2 (0.04% atropine group), Group 3 (0.1% atropine group). During the 2-year intervention period after entering the group, each concentration of atropine eye drops were given every night at a fixed time before going to bed, one drop each time, implemented by parents (supervision), and the wechat small program was completed.
Community Intervention and Demonstration Area Construction
MyopiaRefractive ErrorsThe objective of this intervention study was to understand the visual health status of nearly one million children and adolescents in ten provinces in China, and then to conduct intervention and evaluate the effect of intervention measures with the development of myopia as the outcome indicator. The study will be conducted in the form of a stepped intervention and will answer the following questions. Current China children and adolescent's vision health, including the different degrees of myopia prevalence, and farsightedness reserve status. To evaluate the implementation and effect of eight appropriate technologies and six interventions developed in this study, to reduce the incidence of myopia among children and adolescents in China, to achieve the purpose of nationwide application. In the early stage of this study, a baseline survey will be conducted on participants. In the middle stage, participants will be required to adjust the seat height regularly and increase the time for outdoor activities, etc. In the later stage, intervention measures will be evaluated based on the overall research situation to consider national promotion.
To Study the Effects of Baby Drink on Vision Care
MyopiaBaby Drink is a formula based on lutein, mixed with blueberry fermented liquid, vitamins and minerals. Lutein is an effective antioxidant to prevent retinal damage caused by blue light, but it cannot be produced in the human body and depends on dietary intake. Blueberry fermented liquid is rich in polyphenolic compounds with excellent antioxidant capacity and the potential to reduce oxidative damage to eye cells caused by ultraviolet rays. With the prevalence of 3C products, myopia patients are increasing year by year in various regions, and suffer from eye diseases or vision loss with different degrees of complications. In this study, the subjects were provided with Baby Drink and tracked the degree of visual fatigue by regular questionnaires, and measured for visual acuity, axial length and diopter. The aim of this study is to investigate the protection of Baby Drink on visual acuity and visual fatigue.
