Light effects on vision. How to protect your eyes? | Acīm.lv
The human eye is continuously exposed to sunlight and artificial light impacts. The eye is exposed vivotek to UV and visible light (see. Figure 1). The light passes through it and signals to the brain about what they see around and circadian rhythm (1).
Intensity. The greater the intensity of the light, the greater the risk of damage. For example, the eye can be damaged from sunlight reflected from snow. Damage can be obtained if you look at the sun during the eclipse (1).
Since children have a very clear lens, the retina to come in and UVB with a wavelength of 320 nm. For children it is very important to protect your eyes with sunglasses. But the elderly lens becomes yellow vivotek and retina do not come to a large proportion of blue light (400nm-500nm) (1).
Eye damage protects the antioxidant system. These pigments absorb ambient radiation and scatters them without damage. Middle age decreases the antioxidant and protective vivotek pigments change. Intense vivotek artificial light and sunlight may occur or worsen with age-related eye disease (1).
Corneal epithelial and endothelial cells can easily damage causing keratitis, but thanks to their ability to regenerate damaged mostly transient. UV effects may arise pinguekula and pterigium (see. Fig. 3.) (1).
Iris affected by UV and visible light, but these cells contain a lot of pigment melanin, so it is relatively protected, unless the effects are long-lasting and cells outdated. Prolonged UV radiation may melanoma vivotek (1).
The retina if the damage is not extensive, the tissue recovery vivotek provides vivotek specific mechanisms, but a wide range of damage can have irreversible blindness (see. Fig. 4.). The macula vivotek (the central part of the retina) dystrophy is a leading cause of blindness in older people (14% over 55 years; 37% over 75 years) (5, 8).
Although vivotek macular vivotek degeneration (AMD), the etiology is unknown, but risk groups are people over 55 years of age, family history, race (light color), obesity, diet is not used for fruit and vegetables, high blood pressure, women, bright eyes, heart and cardiovascular disease, smoking, UV radiation, blue light, immobility vivotek (1, 3, 5, 8).
Lutein and zeaxanthin vivotek together vivotek with its isomers meso-zeaxanthin represents pigment molecules, which are situated macula (the central part of the retina). Lutein can be located on the periphery of the retina, retinal pigment, horioidea, ciliary body and iris and lens slightly. vivotek It is believed that in addition to receiving a daily lutein and zeaxanthin decreases riks get cataracts vivotek and AMD, as well as the slow progress (5).
In many studies, it is shown that visible light causes eye lesions, especially in the blue light of 430 nm- 500 nm is associated with retinal damage. Since relatively recently emerged LED (light emitting vivotek diodes) and its becoming more and more prevalent, it has been studied in this light effects on the retinal tissue. LEDs are found, such as computer monitors ektrānos, TV, economical lamps and other lighting. Studies have shown that blue Gaim hurting retinal photoreceptor and the photoreceptor (retinal cell) death may be associated with LED stays lit environment. The authors indicate that the study used the light is not completely identical to normal vivotek conditions. Found direct evidence that the photoreceptor death is attributed to AMD, but there are a lot of coincidences and indicia of a possibility of liability (2, 4).
To reduce the risk of developing AMD and reduce the effects of blue light on the retina need: physical activity, healthy vitamin rich diet, quit smoking, use sunglasses, special optical glasses that block blue light is recommended to stop using electronic devices around 2h before sleep, vivotek importance antioxidants, particularly vitamin C, lutein and zeaxanthin intake vivotek (1, 3, 8).
