A new study in Japan suggests that purple light can suppress myopia, and given the lack of purple light in the room, this finding may help develop new ways to prevent and treat myopia.
Researchers from Keio University in Japan reported in the new international academic journal EBioMedicine that the global myopia population is increasing, and some studies indicate that the outdoor environment helps to suppress myopia, but the specific mechanism of action is still unclear. Researchers at the school's medical department have noticed that purple light with wavelengths between 360 and 400 nanometers is abundant in outdoor environments and rarely in indoors.
The researchers used chickens to carry out animal experiments and found that if the chickens with myopia live in a purple light environment, the expression of the gene EGR1, which inhibits myopia in the body, will increase, and the increase in the length of the eye axis of the chicken will become smaller, that is, the symptoms of myopia will be obtained. control.
In addition, in clinical studies, the researchers compared the situation of wearing different glasses and found that people with myopia lenses that can pass purple light have myopia symptoms compared with those who use contact lenses that cannot pass purple light and ordinary glasses. Get suppressed.
The research team said that because the lighting equipment used in daily life lacks purple light, purple light usually cannot pass through ordinary glasses and glass. Therefore, people in modern society live in an environment lacking purple light, which may be related to the increase of global myopia population. This discovery helps to invent new ways to prevent and treat myopia and control the growth of the global myopia population.
Carbomer
Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.
