Computer Vision Syndrome


Computer Vision Syndrome (CVS), also known as digital eye strain, is a condition that occurs when individuals spend extended periods of time using digital devices such as computers, smartphones, tablets, and gaming consoles, ereaders. Something similar can even haven when using paper sources such as books and newspapers though we typically don’t name it the same. The condition is caused by the prolonged static focal distance, which can cause eye strain, dry eyes, blurred vision, headaches, and neck and shoulder pain.

The symptoms of CVS can vary from person to person, but some of the most common ones include eye strain, eye fatigue, dry eyes, blurred vision, headaches, neck and shoulder pain, and difficulty focusing. These symptoms can be worsened by poor lighting conditions, improper screen settings, and incorrect viewing distances.

An optometrist can provide various services to help diagnose and treat Computer Vision Syndrome (CVS) and other vision-related issues. They can conduct a comprehensive eye exam, prescribe corrective lenses or specialized computer glasses, provide advice on proper ergonomics, offer treatment for dry eyes, and screen for eye diseases. By seeking the assistance of an optometrist, you can receive personalized care to manage CVS and prevent related symptoms.



There are several things you can do to prevent Computer Vision Syndrome (CVS) and reduce the risk of eye strain and other related symptoms:

  1. Take regular breaks: It is important to take frequent breaks from digital screens to give your eyes a rest. The American Optometric Association recommends the 20-20-20 rule: every 20 minutes, take a break and look away from the screen for 20 seconds at something 20 feet away. It may also be helpful to take at least 20 blinks. 
  2. Adjust lighting and screen settings: Proper lighting and screen settings can reduce glare and make it easier to view the screen. Make sure to position the screen so that there is no glare or reflection on the screen, adjust the brightness and contrast settings to a comfortable level, and use a font size that is easy to read.
  3. Maintain a comfortable viewing distance: Position your computer monitor or screen at a comfortable viewing distance, typically about arm’s length away from your face.
  4. Blink frequently: Staring at a screen for long periods can cause dry eyes. To keep your eyes moist, make an effort to blink frequently.
  5. Use artificial tears: Artificial tears can help to keep your eyes moist and reduce dryness.
  6. Practice good posture: Poor posture can contribute to neck and shoulder pain. Make sure to sit with your back straight and your shoulders relaxed.
  7. Get regular eye exams: Regular eye exams can help to detect and treat vision problems before they worsen.

Frequently Asked Questions

The primary symptom of myopia is difficulty seeing objects at a distance, such as road signs or chalkboards. Other symptoms may include eyestrain, headaches, squinting, and needing to sit closer to screens or books to see clearly.

Myopia, commonly known as nearsightedness, is an eye condition where distant objects appear blurry, while close objects can be seen clearly. It occurs when the eyeball is too long or the cornea’s curvature is too steep, causing light to focus in front of the retina instead of directly on it.

The corneal curve is measured using a technique called corneal topography. This non-invasive procedure creates a detailed map of the corneal surface, showing its curvature and any irregularities. During the test, you may be asked to focus on a target, and a specialized instrument captures images of the cornea’s shape. The data obtained from corneal topography aids in assessing tear film stability, identifying areas of potential dryness, and assisting in the diagnosis and management of dry eye.

Yes, the corneal curve can provide insights into the severity of dry eye. An uneven corneal surface can disrupt the tear film, leading to dryness and discomfort. Specialized tests, such as corneal topography, evaluate the curvature of the cornea and its impact on tear distribution. Changes in the corneal curve, along with other clinical assessments, help eye care professionals determine the severity of dry eye and tailor appropriate treatment strategies.

The curve on the front of the eye, known as the cornea, plays a crucial role in dry eye detection. Changes in the corneal surface can affect tear distribution and stability, leading to dry eye symptoms. Optometrists and ophthalmologists use advanced imaging techniques to analyze the corneal curvature and its changes over time. This helps detect dry eye by identifying irregularities that can contribute to tear film instability and ocular discomfort.

The MYAH is a versatile tool that does many things. It measures the length of your eye, checks the shape of your cornea, looks at how your pupil responds to light, and analyzes how light behaves on the front surface of your eye. It can image the meibomian gland structure and tear film height. It’s also helpful for finding the right kind of contact lenses. The MYAH helps keep track of how your eye changes over time, measures your eye’s focusing power, and shows any differences in the shape of your cornea between visits. It can also show how light might be causing some blurriness. So, it’s like a really useful tool for understanding your eye health and helping you get the best lenses if you need them.
