Do you often find yourself rubbing your eyes after an extended workday on the laptop? Excessive watering, eye pain, and headaches are some of the tell-tale signs of eye strain that must not be ignored. This is a condition that can lead to eye fatigue. Sitting in front of a laptop or a computer can cause a strained neck, and back, as well as extreme eye strain. Additionally, many eye conditions such as dry eyes, myopia or even astigmatism can cause your eyes to become tired, if not treated in the right manner. While eye strain cannot cause long-lasting damage, it can lead to you being extremely uncomfortable as well as experiencing blurry vision. Read on to know what causes this eye strain, and how to avoid it.
Eye strain is a common condition that occurs when your eyes get tired followed by prolonged, intense visual activity. “It is usually short-lived and resolves upon resting but in some cases, symptoms can become prolonged and cause discomfort during routine daily functioning,” says ophthalmologist Dr Bhavya Reddy, adding, “This points towards an underlying eye condition that needs to be addressed.” According to a study, published in Ophthalmology and Therapy, Digital eye strain (DES) arises due to the prolonged use of digital electronic devices. The symptoms of this eye strain include dry eyes, itching, foreign body sensation, watering, blurring of vision, and headache.
There are different types of eye strain, depending on the causes as well as the longevity of the fatigue. The most common cause of eye strain is the extended use of screens such as computers, laptops or other digital devices, such as phones and tablets. This can cause eye strain that can either be temporary or long-lasting. Temporary eye strain is extremely common. The American Optometric Association says that when it comes to long-lasting eye strain, the length depends on factors like your screen time, if you are nearsighted, or if you have astigmatism. If eye strain is accompanied by other factors such as headache, dry eyes, and neck or shoulder strain, then it may take longer for the condition to resolve.
There can be many causes of eye strain. Some of them are listed below:
Looking at something at a close distance such as a computer screen, cell phone or a book for prolonged periods can also cause eye strain. “This forces the lens inside the eye into remain in a contracted state which can give rise to symptoms of strain such as tiredness and heaviness of eyelids,” says Dr Reddy. This also results in decreased blink rate which causes dryness of the eyes. The American Academy of Ophthalmology states that this happens because we blink less when we are looking at something closely, for example, a computer screen. We usually blink 15 times a minute, but this gets cut down in half when we are looking closely at something.
Driving requires intense concentration of the eyes. This can often result in fatigue. Make sure to not have any screen time before you drive, and take breaks during your journey, also wearing anti-glare glasses can help reduce eye strain. A study, published in Eye, states that dry eyes can impact the way we drive, as well as other daily activities such as working on a computer. A study, published by the US National Institutes of Health, also states that direct airflow from ac vents or open windows can also make your eyes dry while driving.
Working in a room where there is not enough light can make it hard for your eyes to focus. This can lead to eye fatigue. Working on a laptop or computer in a dark room can also cause eye strain. The American Academy of Ophthalmology states that changing your lighting or taking regular breaks from your work on the computer would help relieve this fatigue.
An uncorrected glass requirement or incorrect glass prescription can also lead to eye strain. In this case, make sure to consult your doctor and get the correct glasses at the earliest.
Many underlying medical conditions can cause eye strain. Dry eye syndrome is one such condition that can increase eye strain. Over-the-counter eye drops can help you fix this. Myopia or being nearsighted, as well as Farsightedness, can also lead to eye strain. For this, you would need to get your vision checked and wear the right glasses. Age-related eye conditions such as presbyopia, a condition where you face difficulty in focusing, can also cause eye strain. A faulty shaped cornea causes astigmatism, and this also leads to eye strain.
There are a lot of conditions that can let you know that your eyes are strained.
To treat eye strain, take regular breaks from screens by following the 20-20-20 rule—take short breaks and look at something 20 feet away for 20 seconds every 20 minutes. Adjust your lighting and screen position to reduce glare and make sure your eyewear prescription is current. Using artificial tears can also help alleviate dryness and discomfort.
