The organs of vision make it possible to receive about 90% of the information. Inadequate lighting, first of all, negatively affects the human visual system. It also affects his psycho-emotional state, the central nervous system suffers.
Uneven lighting can cause accidents. In addition, it can cause adaptation problems in the space of the room. In production facilities, with reduced visibility, the performance of employees is significantly reduced, and also this leads to the appearance of headaches.
Note! Too high a brightness can also negatively affect a person, reducing visual ability.
Types of lighting
Lighting can be of the following types:
Improper artificial lighting disrupts and reduces visual perception, can contribute to the development of myopia and cause other eye diseases.
To prevent local lighting from creating glare on computer screens, they increase the brightness of the screen itself. But still it is better to protect them from direct and reflected light sources. Some believe that by turning off some of the lighting, you can relieve eye fatigue. But this is not so, because at this moment the load on the muscles of the eyes will increase, and over time myopia will form. To cope with such inconvenience during the work, it is better to correctly mark the work tables relative to the light.
Different types of light and their influence
- Incandescent lamps. Everyone knows their negative impact on humans. Many countries have already abandoned them because of the high ripple rate and low light output. They also pose a fire hazard.
- Fluorescent lamps. In the production of such lighting fixtures, mercury is used, therefore, it is impossible to say clearly about their benefits. But not only this dangerous element has a detrimental effect, it is believed that their white light prevents the development of melatonin in the body, which leads to a decrease in immunity and a breakdown of the nervous system. Their flicker, invisible to the human eye, and the stroboscopic effect cause increased fatigue and reduce working capacity. In addition, it should be borne in mind that UV studies can cause skin problems, promote premature aging, and even cause cancer.
- Halogen. They have an iodine glow cycle. It is believed that they are the least dangerous. Their ability to light is very close to natural light. But due to increased pulsation, a stroboscopic effect may appear, which can increase injuries in industrial premises, as well as increase marriage.
- LED bulbs. Today they are considered one of the safe fixtures. They do not have hazardous substances, they are strong enough and durable. Their ability to work is approximately 10 years. They do not radiate heat, therefore they have a high fire safety. LED lamps can increase the efficiency of employees by at least 30%. Their relatively high cost justifies itself by a positive effect on a person.
Particular importance of illumination and compliance with the required standards of illumination is given in classrooms and in the workplace, to create more comfortable conditions for vision.
