The information taken in through this continual scanning movement, known as saccade, or micro-saccade, is communicated to the brain and we are able to perceive what is before us without looking at every detail. The continual saccade is both involuntary and efficient as the eyes travel from bit of information to bit of information forming an understanding of the whole.<\/p><p>The function of the saccade is to continually refresh the information sent to the brain. Each saccade causes the image you see to shift to a different part of the retina. This in turn causes the image to adapts to a new neuron in your eye and brain, and in turn, to be interpreted afresh.

Since humans evolved as hunters and gatherers, our vision was designed for distance. Yes, there was some close-up work; but most of the time our ancestors needed to gaze afar to decide where they could most easily access food and water and to keep themselves safe from potential predators. Our eye muscles are most relaxed when we are using our distance vision. In the absence of mostly close-up work, our grandparents&#8217; eyes flexed continually during the day, from near to far, from far to near. Vision problems arose when long hours of close work in poor light brought eyestrain.<\/p>\n\n<p>Furthermore, we are also designed to move. Sitting all day in one position is unnatural and has consequences for both vision and general health. Studies show that digital device users blink about half as frequently, and the surface of their eyes gets drier.<\/p>\n\n<p>Staring at your computer for long hours without a break strains your eyes and bodies and results in computer eye strain. Studies show that computer users blink less often, which, Japanese researchers indicate, greatly increases one&#8217;s risk of developing short-term dry eye syndrome.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0f0fae8 cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-heading\" data-id=\"0f0fae8\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Consequences of Computer Eyestrain<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ec910bf cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-text-editor\" data-id=\"ec910bf\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Computer eyestrain is a contributing cause to a host of eye conditions including glaucoma, dry eye, advanced macular degeneration, damage to rods and cones, damage to the retinal pigmented layer of macula, and eye cancer.<\/p><p>In one study with university students regarding computer use and eye problems, many exhibited eye issues including the following: headache (53.3%), burning sensation in the eyes (54.8%) and tired eyes (48%).

Since humans evolved as hunters and gatherers, our vision was designed for distance. Yes, there was some close-up work; but most of the time our ancestors needed to gaze afar to decide where they could most easily access food and water and to keep themselves safe from potential predators. Our eye muscles are most relaxed when we are using our distance vision. In the absence of mostly close-up work, our grandparents&#8217; eyes flexed continually during the day, from near to far, from far to near. Vision problems arose when long hours of close work in poor light brought eyestrain.<\/p><p>Furthermore, we are also designed to move.

The sun also emits blue light, so we are at risk for exposure while outdoors as well.<\/p><p>Because blue light is a short wavelength, it has more energy and \u201cflickers\u201d more easily than longer, weaker wavelengths. While not superficially noticeable, blue light creates glare, reduces visual contrast, affects vision acuity, and causes general eyestrain, headaches, and fatigue. The damaging effects of blue light are more serious in low light conditions when the pupil is enlarged and takes in more light. Consequently, the retina receives a larger dose of blue light.<\/p><p><b>Note.<\/b>\u00a0In natural light, blue light is combined with other spectrums of light that helps us maintain our circadian-rhythm. Artificial light at night can confuse out brains into thinking it is still daytime, affecting our ability to sleep well. The lack of blue light at night stimulates the pineal gland that produces adequate amounts of melatonin, which helps us sleep.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-e2af871 e-con-full e-flex cmsmasters-block-default e-con e-parent\" data-id=\"e2af871\" data-element_type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-9626ee5 e-con-full e-flex cmsmasters-block-default e-con e-child\" data-id=\"9626ee5\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-e9ab433 cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-heading\" data-id=\"e9ab433\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Other Blue Light Vision Damage<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c95b0d6 cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-text-editor\" data-id=\"c95b0d6\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h5>Blue Light Damages Rods and Cones<\/h5>\nRecent research using mice helps explain just how and why the eye is damaged by blue light. Mice that were exposed to high levels of blue light displayed the following characteristics:\n<ul>\n \t<li>Massive irreversible cell death that was identified as shrinkage of protein, DNA, and RNA from both the inner and outer layers of photoreceptor rods and cones.<sup>9<\/sup><\/li>\n \t<li>Leaking and rupture of fine capillaries in retina cone photoreceptors.<\/li>\n \t<li>Edema or swelling of the retina.<\/li>\n \t<li>Development of cystoid spaces (cysts) further indicating edema.<\/li>\n \t<li>Changes in expression of certain proteins.<\/li>\n \t<li>Inner blood-retinal barrier damaged.<\/li>\n<\/ul>\nIn humans, this translates to widespread leaking and rupture of tiny blood vessels in the photoreceptor level of the macula, in turn, damaging the remainder of the macula. This may be expressed in a number of vision conditions, such as macular degeneration, choroid neovascularization, macular edema, retinitis pigmentosa, macular pucker, Stargardt\u2019s, cone-rod dystrophy, and diabetic retinopathy.\n<h5>Rod Cell Protein<\/h5>\nThere\u2019s a light-sensitive protein called rhodopsin that is found in photoreceptor rod cells that supports vision in dim light. Rhodopsin levels are low in bright light and high in dim light. This protein triggers retinal damage by blue light during dim lighting conditions.<sup>10<\/sup>\u00a0Furthermore, rods are more sensitive to blue light than cones, exacerbating the problem.<sup>11<\/sup>\u00a0This is the reason that it is important to not use computers or smartphones emitting blue light during dim light conditions.\n<h5>Retinal Pigment Epithelium (RPE)<\/h5>\nRetinal pigment epithelium is a single-cell layer within the retina that provides nourishment to the photoreceptor cells and protects the division between the retina and the rest of the eye. It contains pigmented granules that absorb scattered light; it secretes a number of signaling photochemicals; it forms an immune-safe barrier between the photoreceptors and blood vessels; and it is an essential part of the vision process. Blue light harms the RPE, but just how is somewhat obscure. It is clear that such damage does occur, and that filtering, as with amber glasses, prevents such damage.<sup>12<\/sup>\n<h5>Eye Cancer<\/h5>\nBlue light is associated with significantly increased rates of cell division (mitosis), implicating it in uveal cancers. In some animal models, blue light was found to markedly increase the rate of cancer cell proliferation. In other animal studies where no uvea melanomas previously existed, exposure to blue light contributes to development of such cancers. Blue light stimulates the development of DNA lesions, especially in the presence of free radicals.<sup>13<\/sup>\n<h5>Biochemical Change<\/h5>\nA study published in 2018 found that blue light changes and damages a signaling biochemical, phosphatidylinositol 4,5 bisphosphate (PIP2), causing cell death; alpha-tocopherol reduces the change.<sup>14<\/sup>\n<h5>Insomnia<\/h5>\nThe pineal gland secretes the hormone melatonin; this is the body\u2019s biochemical signal of biological darkness, in other words, the signal that you are ready for sleep. Blue light suppresses production of melatonin<sup>15<\/sup>\u00a0to a surprisingly profound degree.<sup>16<\/sup>\u00a0If you are exposed to blue light right before bedtime (e.g. checking your email one more time), it throws off the internal rhythm that allows you to get adequate sleep. Nearly 75% of children now use some sort of electronic device in their bedroom. The use of these devices markedly impacts sleep quality, which in turn, contributes to social adjustment problems, behavioral problems in school and at home, and surprisingly, weight gain.\n\nWhile most research on the effects of smartphones on sleep and circadian rhythms have involved children and teens, adults are also adversely impacted. One Flemish study included more than 800 adults, 50% of whom owned smartphones, and 60% of whom used their smartphone during the night. Nighttime phone use and texting at night markedly increased how long it took to fall asleep and markedly decreased the quality, duration, and efficiency of sleep.\n<ul>\n \t<li>In younger adults, nighttime electronic-device use was tied to more fatigue and later rising time.<\/li>\n \t<li>In older adults, it was associated with shorter sleep duration and earlier rise time.<sup>17<\/sup><\/li>\n<\/ul>\n<h5>Damage to Macula<\/h5>\nOngoing exposure to blue light increases the risk of neovascular (wet) macular degeneration, particularly associated with low levels of antioxidants, and especially low levels of vitamin C, zeaxanthin, and vitamin E.<sup>18<\/sup>\u00a0Another study suggested that extended exposure to sunlight outdoors may be associated with age-related maculopathy.<sup>19<\/sup>\n\n<img decoding=\"async\" src=\"https:\/\/naturaleyecare.com\/wp-content\/uploads\/2025\/05\/menu-terms.jpg\" alt=\"\" \/> To learn more about damage due to blue and UV light, and how you can protect your vision through diet, lifestyle, and nutrition, read our newly updated complete guide:\u00a0<a href=\"https:\/\/store.naturaleyecare.com\/nec-book.html\">Natural Eye Care: Your Guide to Healthy Vision and Healing<\/a>, also available as an e-book, or our\u00a0<a href=\"https:\/\/store.naturaleyecare.com\/natural-eye-care-series-cataracts.html\">mini-book on cataracts<\/a>.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-538ed30 e-con-full e-flex cmsmasters-block-default e-con e-parent\" data-id=\"538ed30\" data-element_type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-344e141 e-con-full e-flex cmsmasters-block-default e-con e-child\" data-id=\"344e141\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-90e21de cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-heading\" data-id=\"90e21de\" data-element_type=\"widget\" id=\"dry\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Blink rate &amp; eye moisture<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-31f2512 cmsmasters-block-default cmsmasters-sticky-default elementor-widget elementor-widget-text-editor\" data-id=\"31f2512\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The tear film and the blinking process also make vision possible.<\/p><p>Tear film is the moisture-laden surface of the eye<sup>2<\/sup>, consisting of three layers (mucus layer, aqueous layer &amp; lipid layer).
