Cause

One of the most common causes of eye strain is computer and digital screen use. Eye strain results from a complex interplay of factors involving the eyes, surrounding muscles, and environmental conditions. Here's an overview of the key aspects:

  • Fatigue of eye muscles: Prolonged engagement in activities such as reading, screen time, or extended driving strains the extraocular muscles (responsible for eye movement and focus), inducing muscle fatigue. Additionally, continuous close-up tasks, like reading or computer work, demand constant adjustment and focus from the ciliary muscle (which adjusts the shape of the lens in the eye to facilitate focusing on objects at different distances), leading to strain and fatigue over time.
  • Reduced blinking: Intense concentration on screens or close tasks often results in reduced blinking. Blinking is crucial for evenly spreading tears over the cornea. Reduced blinking can cause dry eyes, contributing to eye strain.
  • Blue light exposure: Extensive use of electronic devices emitting blue light, such as computers and smartphones, can induce digital eye strain due to prolonged screen focus and exposure to this specific light wavelength.
  • Poor lighting conditions: Struggling to see in low or inadequate lighting forces the eyes to exert extra effort, resulting in eye strain.
  • Incorrect vision correction: Neglecting prescribed glasses or contact lenses, or using outdated or incorrect prescriptions, forces the eyes to work harder to focus, leading to eye strain.
  • Medical problems: Underlying eye conditions like dry eye syndrome, allergies, or uncorrected refractive errors can contribute to eye strain. Additionally, general fatigue or stress may exacerbate discomfort by reducing the eye’s ability to maintain focus.
  • Environmental factors:
    • Humidity: Low environmental humidity can contribute to dry eyes, increasing the likelihood of eye strain.
    • Airflow: Airflow from fans, air conditioners, or heating systems may contribute to dry eyes.

Note: While uncomfortable, eye strain is typically a transient condition that can be alleviated with adequate rest.

RiskFactors

Eye strain can affect anyone, but certain factors may increase the likelihood of experiencing it. Risk factors for eye strain include:

  • Excessive digital device usage: Prolonged use of smartphones, tablets, computers, or other digital devices with screens can strain the eyes due to extended exposure to blue light and reduced blinking.
  • Extensive reading: Jobs that require extensive reading, such as those of editors, researchers, or writers, may increase the risk of eye strain. Here are some workplace safety tips to protect your eyes.
  • Vision problems: Individuals with vision problems are more susceptible to eye strain, especially if they need vision correction but do not use it. Types of vision problems include:
    • Farsightedness (Hypermetropia): Difficulty seeing close objects.
    • Nearsightedness (Myopia): Difficulty seeing things at a distance.
    • Astigmatism: Blurred and distorted vision.
    Vision problems make it challenging to focus the eyes, leading to strain. The effort to focus both eyes, especially when one has more significant issues than the other, can also contribute to eye strain.
  • Dry eyes: Insufficient eye lubrication, often caused by factors like aging, medications, or environmental conditions, can lead to discomfort and eye strain.
  • Age: As individuals age, it becomes harder to focus on close objects, increasing the risk of eye strain, particularly during prolonged near tasks.
  • Fatigue and lack of sleep: Fatigue, tiredness, stressful lifestyles, and lack of sleep can contribute to eye strain. Take care of your vision! Invest in good eye care if prolonged screen time or poor ergonomics cause discomfort or strain.

Diagnosis

The diagnosis of eye strain involves a comprehensive eye examination. The diagnostic process may include the following:

  • Patient history: The ophthalmologist will begin by taking a detailed patient history. They will inquire about symptoms, including the nature and duration of discomfort, activities that worsen or alleviate symptoms, and any other relevant information.
  • Visual acuity measurements: A basic eye test, including reading letters or characters from a chart, assesses visual acuity. This helps identify refractive errors such as nearsightedness, farsightedness, or astigmatism.
  • Refraction test: A refraction test helps determine the appropriate lens power to address refractive errors such as nearsightedness, farsightedness, or astigmatism.
  • Eye muscle testing: This helps identify any issues with focusing or eye alignment. Evaluating how the eyes focus, move, and work together includes assessing the eyes' ability to change focus effectively and work in unison to obtain a clear, single image.
  • Binocular vision testing: Testing how well both eyes work together (binocular vision) helps identify any imbalances that could contribute to eye strain.
  • Slit-lamp examination: A slit-lamp examination allows the eye care professional to examine the eye structures, including the cornea, iris, and lens.
  • Testing under normal seeing conditions: Conducting tests without eye drops to observe how the eyes respond under typical viewing conditions. This helps identify any issues affecting the eyes' ability to focus.
  • Optional use of eye drops: In some cases, eye drops may be used to temporarily prevent changes in focus during testing.
