Prolonged screentime can stress the eyes through the effects of bright or blue light, but it will not produce more eye floaters. However, floaters may be more noticeable when staring at a bright screen or background.
Can screen time cause eye problems such as floaters? Floaters are not associated with screen time. Floaters are caused by changes to the jelly inside the eyeball called the vitreous humour and are unrelated to screen time.
Electronic screens such as smart phones, tablet personal computers (PCs), and liquid-crystal displays (LCDs) emit blue light that accelerates vitreous degeneration, resulting in vitreous opacity and increased floaters, with floating shadows in front of the eyes as the main complaint.
Smartphone vision syndrome, also known as computer vision syndrome or digital eye strain, is a condition that results from prolonged use of digital devices such as smartphones, laptops, and tablets. This can cause symptoms such as eye fatigue, headache, blurred vision, dry eyes, and neck and shoulder pain.
Studies show that people of all ages blink far less often when concentrating on a screen, which in turn causes the eyes to dry out. A clear and stable tear film on the eye surface is essential for clear vision. This problem can be worse for children who may have to look up at a screen that's positioned for adult use.
Vision experts generally don't consider screens as a source of permanent vision damage, even if extended use can cause eye irritation. If you only look at screens for a few hours a day and don't experience any vision issues, you probably do not need to worry.
What causes floaters? Floaters usually happen because of normal changes in your eyes. As you age, tiny strands of your vitreous (the gel-like fluid that fills your eye) stick together and cast shadows on your retina (the light-sensitive layer of tissue at the back of the eye). Those shadows appear as floaters.
You might think they've gone away, but that's not true. Floaters are permanent and stay in your eye. Sometimes, they can be a sign of a more serious eye conditions called retinal tears and retinal detachment.
For some, eye floaters can disappear within a few weeks. For others, it's a matter of months. This depends on the type and severity of the floaters. In some cases, underlying conditions such as a torn retina or diabetic retinopathy can cause eye floaters to feel more apparent or longer lasting.
Eye floaters are surprisingly common, affecting about 7 out of 10 people. They can show up at any time but for a lot of people they become noticeable after looking at something bright, such as the sun. Blinking often causes them to disappear but if you still notice them, eye floaters are usually harmless.
Eye floaters are common, and they might be a nuisance, but they're usually not anything to worry about. If you have a lot of floaters that appear suddenly, or other eye symptoms along with eye floaters, seek medical care right away.
Options may include surgery to remove the vitreous or a laser to disrupt the floaters, although both procedures are rarely done. Surgery to remove the vitreous. An ophthalmologist who is a specialist in retina and vitreous surgery removes the vitreous through a small incision (vitrectomy).
For many, floaters may begin showing up between 50 and 70 years old. "Vitreous degeneration is accelerated by nearsightedness (myopia), inflammation, trauma and rare inherited abnormalities," adds Dr. Worrall. "Highly nearsighted patients tend to have more floaters than average."
Eye floaters are a result of eye fatigue. A prolonged lack of sleep puts stress on your eyes which is one of the initial symptoms and can lead to eye floaters. Hence, it's important to relax your eyes and take enough rest & sleep in order to heal.
Can eye floaters fluctuate from day to day or throughout the day? Yes, they can vary in different light conditions and can appear more prominent against light backgrounds. Some people notice floaters more when they are tired or at the end of the day.
Research has indicated that stress and anxiety can trigger the formation of floaters in the eyes. Therefore, find ways to manage your stress levels, and you'll improve your eye health. Some stress management techniques include: practicing yoga, meditating, exercising, and spending time in nature.
Eye floaters are a very common symptom of anxiety and, in most cases, should not be worried about.
If you notice a sudden increase in eye floaters, contact an eye specialist immediately — especially if you also see light flashes or lose your vision. These can be symptoms of an emergency that requires prompt attention.
Vitamins & Supplements
Ginkgo biloba, omega-3 fatty acids, and zinc are recommended by dieticians and natural medicine advocates for improving blood flow and promoting better vision, and this may be a tool to mitigate the presence of floaters.
Most people see floaters some time during their lives. Many individuals notice some floaters even in their teens and 20s, and people who are nearsighted are particularly likely to have floaters at a younger age. Floaters tend to become more frequent as a person ages.
Excessive screen time has been shown to have negative effects on children and adolescents. It's been linked to psychological problems, such as higher rates of depression and anxiety, as well as health issues like poor sleep and higher rates of obesity.
This time spent sitting and viewing a screen has been linked to mental health effects such as anxiety and depression. Adults who spend six hours or greater using screen time are more likely to suffer from moderate to severe depression.
So how much screen time is too much? And (maybe most important) — how do we scale back? "Most experts agree that adults should limit screen time to less than two hours per day outside of work-related activities," Dr. Moghaddam says.
