Most people have experienced eye strain and for many, it occurs regularly as a result of their daily activities. Eye strain is not an eye condition, but a symptom of overworked eye muscles and may also be a sign of vision loss.
For the most part, eye strain is a result of a common daily task like reading, using a computer or phone, or even driving. It is usually not a cause for concern, but it can lead to a series of frustrating and uncomfortable symptoms that make daily life difficult. In this article, we will show you the best ways to prevent and treat eye strain, and how to know when it might be a sign of vision loss or an eye condition.
Eye strain from using screens for extended periods is extremely common and is usually referred to as digital eye strain or computer vision syndrome. As many people use computers and phones for several hours a day and as an essential part of their work and home life, it is especially important to know how to minimise digital eye strain and treat it effectively.
The eyes use a series of muscles to focus and like any other muscles in the body, they can become tired and tense. So, when you engage in tasks that require long periods of focusing you may experience eye strain. Common causes include:
The causes of eye strain are for many of us an unavoidable part of our daily lives, whether it be a long commute to work or an office job that requires spending hours in front of a computer. Fortunately, there are ways to prevent and treat eye strain, which will be outlined below.
Occasionally, eye strain is the result of an eye condition or visual impairment like myopia, hyperopia or astigmatism. In these cases, the eyes are having to work hard to cope with vision loss. If you experience eye strain together with frequently blurred vision at near and far distances or problems with your vision in general it may be time to book a comprehensive eye exam with your optometrist.
People experience eye strain differently and there are a wide range of symptoms, some of which are more common with digital eye strain. The most common symptoms of eye strain are:
Today, digital devices are a part of children's education, entertainment and social lives. They face a unique set of challenges when it comes to using these technologies in a way that protects their eye health and well-being.
Digital eye strain caused by extended screen time can arise from long hours playing video games or watching television, but also from studying or attending classes online. One study looked at how children engaged in online learning were affected — research showed that when they spent more than 4 hours using a computer they began to experience symptoms that included eye strain, headaches, eye dryness and blurred vision (Kozeis, 2009). Taking regular breaks, spending time outdoors and limiting screen time where possible can help to reduce digital eye strain for children. If your child is regularly experiencing eye strain, especially when combined with other vision problems, it is a good idea to have their eyes examined by a qualified optometrist. In the next section, you can read about more ways to prevent and treat digital eye strain for adults and children.
Digital eye strain and its associated symptoms can pose significant challenges for school-age children. The fatigue, discomfort and vision problems caused by eye strain can lead to difficulties concentrating, limit reading comprehension and affect academic confidence. As a parent, looking out for signs of digital eye strain like eye rubbing and difficulties reading or concentrating on tasks can help you to take preventative action when needed.
Eye strain is a temporary condition usually caused by certain activities and tasks. Usually, the best way to treat it is through taking regular breaks from the activities or environment that brings it on. If eye strain is being brought on or exacerbated by another condition, then it is important to ensure it is being corrected or treated properly and that your prescription is up to date.
Eye drops or ‘artificial tears’ are also an available option that some people find give them relief from eye strain – they work by keeping the eye moist to avoid irritation. However, eye strain will usually have a root cause, which is important to address if you want to limit it in the long run.
Learning how to prevent eye strain is perhaps the best way to limit its effects on your daily life. Here are some preventive methods you can use to reduce eye strain:
Eye strain varies from case to case, so finding what brings it on for you can help to prevent it. Nevertheless, following the advice above can help to limit the amount of work your eyes have to do and minimise strain and discomfort.
