Does Computer Blue Light Cause Macular Degeneration?

Table of Contents

Many employees devote long hours each day to using digital devices, and exposure to the blue light from these screens may cause eye strain and impact sleep quality by altering natural production of melatonin.

Encourage your team to take regular screen breaks. Step away for at least 20 minutes every 20 minutes in order to give their eyes a rest and reduce their risk for computer vision syndrome.

Blue light

Blue light is a high-energy part of the visible spectrum that radiates high energies, penetrating your eyes’ corneas and lenses before reaching your light-sensitive retina and being converted to signals your brain can interpret as images. Blue light has been proven to increase alertness, focus, memory retention and mood improvement; daylight also contains this element, helping regulate sleep/wake cycles while improving overall well-being; however overexposure via digital device screens may interfere with this natural process and disrupt it, potentially interfering with sleep cycles as well as mood enhancement.

Eye strain, usually manifested by blurred vision, dry eyes, headache and fatigue can occur from prolonged digital device usage. Furthermore, this strain may lead to computer vision syndrome – which causes painful sensations in your backhead neck shoulders – as well as computer vision syndrome which has its origin in extended digital device use.

Problematic, extended use of phones, computers and tablets forces our bodies into unnatural positions known as “turtling,” wherein we shift around in our chairs until our back and shoulders round out, round our chin forward and slump forward in chairs slouching in chairs causing the eyes to strain overtime and eventually leading to symptoms associated with computer vision syndrome.

Studies have revealed that extended exposure to blue light from digital devices can have detrimental effects on our vision and even increase the risk of macular degeneration, while disrupting sleep cycles and negatively influencing other areas of health in the body.

There are various methods available to reduce exposure to blue light from digital devices. Many computer and smartphone manufacturers include options in their software to limit how much blue light their displays emit; third-party apps and hardware filter out any excess. Unfortunately, however, none of these solutions is as effective as changing display settings or wearing blue-blocking glasses – these tend to reduce color gamut output and may produce less vibrant images; for this reason many ophthalmologists suggest limiting screen time or using a blue-light filter in the evening in order to guarantee quality sleep while protecting long-term health benefits.

Age-related macular degeneration

Age-Related Macular Degeneration, or AMD, occurs when light-sensing cells within your macula start to slowly break down and stop functioning properly over time. Macular Degeneration is one of the leading causes of severe vision loss among those over 50, making it hard to read, drive and see faces clearly. Macular Degeneration usually starts in one eye before gradually spreading to both; its severity ranges from mild dimming or distortion to complete blindness – though most AMD cases only affect central vision without impacting peripheral or side vision vision as it does with other causes of blindness such as these conditions.

Blue light concerns arise due to its proximity to ultraviolet rays on the electromagnetic spectrum, which are capable of gradually damaging eyesight over time. But while digital device screens emit much lower levels of blue light than sunlight does and have never been shown to cause retinal damage or macular degeneration; while long-term overexposure to blue light does increase your risk for serious conditions like cataracts, pterygium, and cancer – it does not result in significant eye damage directly.

Cataracts block out most blue light from reaching your retina; once they have been extracted, however, you are more vulnerable to wet macular degeneration; this type of macular degeneration characterized by abnormal blood vessels proliferating beneath your retina that leak fluid and blood.

Your doctor can diagnose macular degeneration with an exam and imaging technique known as optical coherence tomography (OCT) to scan your retina for fluid and blood accumulation. During this test, dye is injected into a vein in your arm before the images captured reveal any fluid accumulation or leakages on retina blood vessels. If you suspect you’re experiencing signs of macular degeneration it’s essential that you schedule an appointment immediately with an ophthalmologist.


Blue light from computer and digital devices can harm the retina, particularly the macular area, leading to macular degeneration, which is a progressive condition resulting in central vision loss and other symptoms such as blurry or hazy vision, difficulty seeing in low light environments, and glare sensitivity. If these symptoms arise for you, make an appointment with a retinal specialist immediately so they can determine whether macular degeneration exists.

Cataracts can occur due to age, exposure to UV rays, eye diseases, or other medical issues. Cataract symptoms include cloudy or blurry vision, decreased contrast and color, eye strain or fatigue and an inability to perform daily activities like driving at night, reading books or engaging in sports or hobbies that require good vision. They’re one of the primary causes of visual disability in America and impede daily living activities like driving at night, reading or engaging in physical sports and hobbies that rely on clear eyesight.

Blue light exposure is linked with eye strain, sleep disturbances and disruption of circadian rhythm – all contributing to age-related macular degeneration and other eye health problems. LED screens emitting blue light can disrupt retinal photoreceptor cells leading to oxidative stress, mitochondrial apoptosis and DNA damage of corneal epithelial cells of the eye resulting in damage that must be repaired later.

Although the long-term effects of excessive blue light exposure remain uncertain, doctors recommend that patients limit their time spent on digital devices and take frequent breaks while also using screen filters to lower the amount of blue light reaching their eyes and prevent eye strain. Other preventive techniques may include using artificial tears to lubricate eyes while sitting arm’s length from the device and dimming lighting around its display screen.

Emmetropia is an indicator of overall eye health; however, it doesn’t guarantee perfect vision or prevent disease in the future. Even if you have emmetropia, it is still important to protect your eyes by taking steps to limit blue light exposure and scheduling regular eye exams – contact Empire Retina Specialists now for more information on how you can protect yourself from harmful blue light exposure!

Eye strain

Eye health experts and researchers are increasingly concerned about the long-term effects of exposure to blue light from digital screens. They fear it could cause symptoms including vision problems and long-term eye damage; as well as increase macular degeneration risks over time.

Scientists have long discovered that prolonged exposure to blue light can result in various symptoms, including eyestrain and headaches. This condition, known as computer vision syndrome or CVS, typically develops when someone uses digital devices such as computers for extended periods and struggles to see clearly on screen – symptoms may include squinting eyes, dryness in eyeballs blurred vision fatigue headache and neck/back discomfort as well as neck or back ache.

Researchers suspect that the increasing intensity of blue light emitted from computers and digital devices can contribute to CVS. They believe the longer someone spends in front of screens, the higher their risk for CVS and macular degeneration later on in life.

Companies have started marketing special lenses that filter out blue light in order to reduce eye strain and macular degeneration risks, according to some claims from companies marketing them. Unfortunately, this type of lens has yet to prove effective at either lowering eye disease risks or improving vision; accordingly, the AAO suggests people limit screen time, take frequent breaks between viewing sessions, use artificial tears when necessary and adjust lighting to avoid any glare caused by glass screens.

If you or any of your employees are experiencing eye-related symptoms such as squinting, it’s essential that they visit an ophthalmologist for a comprehensive eye exam. A full eye exam can detect and pinpoint the source of discomfort or vision issues like CVS or macular degeneration; additionally, your provider can suggest prescription glasses or contact lenses equipped with anti-reflective coatings and blue light filters to minimize eye strain from extended digital screen use and help protect macular tissue damage.
