When reading, be careful with your eyes, and the most important of all eye care techniques is proper lighting.
Consider your lighting. Although it is now possible to provide everyone with suitable scientific lighting, most people view lighting fixtures from the perspective of decorative value rather than value to the eyes. There is no reason why it cannot be decorative and practical at the same time, but it does not make sense to choose it mainly for decorative purposes.
Lighting companies often provide you with free services to analyze appropriate lighting needs, and there are many free brochures offering the same services. Good light is essential for eye health, and bad light certainly affects the eyes, just as bad air affects the lungs.
When planning a lamp to suit your reading needs, there are three important points to keep in mind:
1. There must be enough light.
2. There should be no glare.
3. There should be good general lighting in the room. In other words, the space should be as bright as the page you are reading. Therefore, do not use reading lamps and do not switch on other lamps.
Research has just begun to shed light on the important effects of lighting on vision and overall health. Matthew Luckiesh pointed out the great impact of good lighting in offices and factories in “Light, Sight and Sight”:
He wrote, “In terms of tangible and intangible benefits, what can be deduced from a higher level of vision and good vision conditions in general is:
1. Improve the execution rate of useful work and thus reduce costs.
2. Improved accuracy, can work better and reduce material wastage, reducing costs.
3. By reducing eye fatigue, nervous tension, eye fatigue, general fatigue, irritability and mental fatigue, the visibility of the vision is increased, saving human resources such as vision, energy and time.
4. Improved safety through fast, secure and easy vision, reducing massive material and personnel losses from avoidable accidents.
5. The moral increase caused directly or indirectly by the above and other psychological factors, such as a pleasant environment, is an inevitable consequence of good visual conditions. “voltage.
This is one of the lesser known eye care techniques. Not only should the room itself be adequately lit, but to relax the eyes and get the maximum light, it will help a lot if the walls themselves are light in color. Dark colors absorb light, while light colors reflect light. The darker your walls, curtains and furniture interiors, the more light you will lose.
Since glare can cause eye strain, always sit down so that the light falls directly on your left shoulder and directly onto the printed page. Do not read directly.
When reading with artificial light, it is recommended to use a tall desk lamp with a 150 watt incandescent lamp. Place the lamp on the table to the left of the chair. To avoid reflections on the printed page, try the following simple test: Place a small pocket mirror in the center of the page. If the lamp reflects in the mirror, move the lamp until the eyes on the printed page can no longer see the light in the mirror.
People who like to read pet chairs ignore the fact that there may not be enough light near the page. People began to read in bright sunlight, deepened, not noticing that as dusk set, the light got darker and darker until they tried to recognize the text on the printed page.
Lighting and posture problems are important for healthy eyes and for eyes with certain defects. In the latter case, their negligence has hardly committed any criminal offenses. Paying attention to the above eye care techniques will bring many benefits.
