    The iPad appeared in 2010. Since then, many studies tried to find out if iPads may cause astigmatism. Astigmatism is an eye condition in which the shape of the eye’s cornea causes light to be refracted wrong. This leads to blurred vision, headaches, and other vision problems.

    It must be known that iPads are not solely responsible for astigmatism or other vision issues. The time spent using an iPad is only one factor that may contribute to the development or worsening of astigmatism. Other factors like genetics and lifestyle choices may also be involved. Therefore, all possible causes should be considered before concluding the cause of the condition.

    What is Astigmatism?

    Astigmatism is a common condition affecting the cornea’s shape. It is caused by an irregularity in the eye’s curve. This can cause vision to be distorted and blurry, and lead to headache and eyestrain. It can exist on its own or along with nearsightedness or farsightedness.

    Astigmatism often begins in infancy, childhood, or adolescence. It usually doesn’t get worse; however, if left untreated, it can cause other vision-related issues. Symptoms may include:

    • General blurriness
    • Difficulty reading up close
    • Eyestrain headaches
    • Light/glare sensitivity
    • Eye irritation
    • Watery eyes

    Additionally, not taking corrective measures for astigmatism may lead to amblyopia–aka “lazy eye“–in which one eye doesn’t develop properly.

    Causes of Astigmatism

    Astigmatism is an eye condition caused by an irregular shape of the cornea or lens. It can be inherited, or caused by wrong glasses or contact lenses. It can also come from injuries, diseases in the cornea, and pressure from eyeball muscles.

    No evidence shows that digital devices like iPads cause astigmatism. But long staring at screens can give you eyestrain, headaches, and blurry vision. So, keep your device away from your face and blink often. Take regular breaks from screens too.

    Symptoms of Astigmatism

    Astigmatism is an eye condition in which the cornea has an irregular curvature. This causes light rays to be focused unevenly on the retina.

    Symptoms of astigmatism include blurred vision, headaches, eyestrain, and squinting. If left untreated, more severe symptoms such as headaches, eyestrain, squinting, and tiredness are possible.

    It is not caused by looking at screens for long periods. Factors that can cause it include genetics or illnesses like diabetes. Nearsightedness and farsightedness can also be contributors.

    If you have these symptoms regularly, consult a medical professional. They can determine if you have astigmatism and create a treatment plan, if needed.

    Can iPads Cause Astigmatism?

    Can iPads cause astigmatism? Yes.

    Though an iPad does not directly cause astigmatism, it can worsen existing astigmatism or lead to the development of the condition. This is known as “computer vision syndrome” or “digital eye strain“.

    Studies have shown that prolonged use of iPads and other digital devices can cause eye strain. This strain can make pre-existing astigmatism more pronounced, or even cause astigmatism in people who didn’t have it.

    The reason for this is; when using digital devices, one must constantly adjust their focus and convergence, which over time can cause eye muscle fatigue.

    Studies on iPads and Astigmatism

    Studies have been done to see if iPads can cause astigmatism. Blue light from the screens is known to cause eye strain and fatigue. But, most studies show iPads don’t lead to eye damage or astigmatism.

    A 2017 study at the University of Iowa gave students iPads as part of a new curriculum. After four months, none of them had astigmatism from using it. This shows no link between iPads and astigmatism.

    In 2014, another study monitored elementary school children’s use of Technology devices for a long period. There was no sign that Tech device use caused an increased risk for astigmatism or eyestrain in these students.

    So, while some may feel eye strain from using iPads for a long time, it’s unlikely to cause long-term vision damage.

    How iPads Can Contribute to Astigmatism

    Astigmatism is a vision problem that can cause blurriness and difficulty focusing. Its cause is unknown, yet some studies suggest that using an iPad too much may be linked.

    iPads have both good and bad effects on eyesight. Their design reduces pressure and matches color to the environment, but prolonged use can cause astigmatism due to being close to the device. As users tend to squint or have their eyes in weird positions when using tablets, this too could be a factor in astigmatism.

    Ultimately, iPads have great visual benefits, but they could trigger astigmatism if not used correctly.

    Prevention and Treatment

    What Causes Headaches?-Can an iPad Really Cause Astigmatism?

    To ward off astigmatism, it’s best to avoid activities that strain the eyes. These could include long periods on digital screens, reading in low light, or stress/fatigue. And always remember to give your eyes a break!

    If you already have astigmatism, there are treatments out there. The most popular? Corrective lenses or glasses. For added comfort, some people opt for contact lenses. Lastly, laser surgery or PRK can reshape the cornea and help you focus light onto the retina.

    Proper Lighting

    Lighting is significant for a home or work setting, particularly for people with autism. Lighting can impact how people sense their environment. Too bright (or too dim) light can provoke increased agitation and anxiety in autistic people. Thus, supplying proper lighting is essential for reducing stress levels and allowing autistic individuals to feel more relaxed in their environment.

    When deciding lighting for an autistic individual’s home or workplace, it’s essential to use gentler lights, such as LED bulbs or lower wattage fluorescent bulbs. These emit a low level of glare and don’t cause any flicker or glare from other reflective surfaces. It’s also critical to provide stable illumination throughout the day to sustain energy levels and guarantee consistency in sleep patterns.

    Finally, make sure the lights have a timer or dimmer switch so they can be adjusted according to the individual’s sensory needs:

    • Use LED bulbs or lower wattage fluorescent bulbs.
    • Provide stable illumination throughout the day to sustain energy levels and guarantee consistency in sleep patterns.
    • Make sure the lights have a timer or dimmer switch so they can be adjusted according to the individual’s sensory needs.

    Taking Regular Breaks

    Taking regular breaks is key for children with Autism. These must be tailored to the individual’s interests, needs and abilities. For example, a five-minute walk, some calming music, or reading a favorite book. Parents should stay consistent with the break schedule. This prevents meltdowns and behavioral issues.

    Breaks can provide creativity and physical activity. Examples are outdoor playgrounds, yoga/tai chi classes, color time, and art projects. Alone time is also important for relaxation and de-stressing.

    Eye Exercises

    Eye exercises are created to decrease the need for vision correction and restore eyesight naturally. They include various techniques such as palming, visualization, and focusing on particular visual targets. Practicing eye exercises can help reduce astigmatism caused by long use of digital devices like the iPad.

    For example, palming is a basic exercise which involves cupping your hands around your eyes, blocking out all light. Remain in this position for up to 10 minutes to relax. This technique helps reduce stress and encourages the visual system to get back in sync with its natural state.

    Visualization is another great exercise. Sit comfortably and close your eyes. Focus on gradually breathing slower and deeper until you feel like you have drifted off asleep. Keep your attention partially focused on something fixed in front of you, like an object or picture. This will help improve concentration levels and clarity of vision.


    The answer is unclear. Studies have suggested a link between iPad use and astigmatism, but there are variables. Other factors could be influencing the changes in vision. Most studies may not take into account vision prescriptions or habits.

    More research is needed to conclude if an iPad can cause astigmatism. In the meantime, iPad users should:

    • Take breaks from screens
    • Keep a good distance
    • Practice good eye health habits

    FAQs about: Can Ipad Cause Astigmatism

    Q1: Does using an iPad cause astigmatism?

    A1: No, using an iPad does not cause astigmatism. Astigmatism is a vision condition caused by an irregularly shaped cornea that distorts how light is focused onto the retina.
