Selection of lamps for the elderly

- The amount of light reaching the retina of the eye is reduced. As the age increases, the light transmission capacity of the cornea and lens of the elderly decreases and the pupil shrinks, so that the amount of light reaching the retina of the eye is reduced. The amount of light reaching the retina by the 60-year-old is 20 years old. 30% of young people, only 12% at 75 years old;

- the number of neurons in the retinal photoreceptor and the visual pathway is reduced, causing a decrease in photosensitivity and conductivity;

- Regulatory decline and presbyopia, which began after the age of 40.

Therefore, it is necessary to improve or compensate for the shortage of general lighting by improving illumination and uniformity to meet the lighting requirements of the elderly. The following points should be noted when selecting lamps for the elderly:

- The selected desk lamp power should be able to produce 1000 lx illumination on the desktop;

- The eyes of the elderly are still more afraid of glare, and the lamps for writing, reading and bedroom should be shaded.

- Focus on color rendering and color temperature. When selecting the light source, it is necessary to avoid the use of products with high color temperature and low illumination, so as not to make the patient feel dark and cause feelings of low mood. Therefore, it is best to use lamps with color rendering greater than 80 and color temperature not exceeding 4000K.

- In order to ensure the safety of night and night, the lighting of the elderly bedroom leading to the bathroom should be lighted to ensure the safety of walking at night.
