Do you know that China currently ranks first in the world in terms of myopia population, with an 80% myopia rate among urban adolescents, and there are more than 600 million myopia patients nationwide. From the first time I started writing, heavy schoolwork, ever-changing electronic devices, and various games, film and television works are occupying our eyes all the time, without reasonable rest and use, the occurrence of myopia seems to be is an inevitable result.
Myopia is mainly divided into three categories: mild myopia (less than 300 degrees), moderate myopia (300-600 degrees), high myopia (more than 600 degrees); mild and moderate myopia can be corrected before adulthood. There are many factors that affect vision. Due to the pressure of life, work and study, we often need to use our eyes at a high intensity. Today I mainly want to talk about a factor that is easily overlooked by us: lighting.
Our pupils will shrink due to the intensity of the light. When the ambient light is dark, the pupils are enlarged and more light enters; when the ambient light is strong, the pupils shrink and the incoming light is reduced. Take a mobile phone as an example, the ambient light is dark. At the same time, due to the pupils trying their best to capture light, the pupils are in a state of frequent changes in dilation and contraction, which will increase the intraocular pressure, and there is a risk of glaucoma and retinal detachment. As a family member of a retinal detachment patient, this seemingly uncommon but extremely dangerous condition is actually not far away from us. Because when your strength reaches more than 600 degrees, the pathological increase in the axial distance of the eye will cause the eyeball to change from spherical to olive-shaped. The slightest trauma can cause the retina to tear and then fall off.
How is the right lighting defined? There are two points to note:
1. According to the results of the lighting experiment, the human eye will feel more comfortable with the light of 200~400 lumens. At the same time, the higher the uniformity of light, the less irritation to the eyes. Compared with traditional centralized lighting, multi-point lighting is easier to be accepted.
2. In terms of color, the closest to natural light is the neutral light 4000K, which is between white light and warm yellow light, with a faint yellow light, similar to the sunlight at eight or nine in the morning. This color of light is the most suitable for us to work and study.
In addition, the star products that protect vision in plant extracts are also worth taking. They all have the effect of protecting vision, preventing glaucoma and improving blindness, mainly related to their antioxidant properties, they are:
Marigold Extract--Lutein
Bilberry Extract - Anthocyanins
Blueberry Extract--Anthocyanin
