WHAT IS COMPUTER VISION SYNDROME?

Computer Vision Syndrome (CVS) and Digital Eye Strain (DES) are interchangeable. They’re terms used to describe the visual discomfort and eye-related problems that result from prolonged use of digital devices (e.g. laptops, smartphones, and tablets). In this article, we refer to CVS - but we’re referring to both.

The prolonged use of these devices can strain the eyes, leading to various symptoms (detailed below). The syndrome can cause discomfort, eye strain, and decreased visual performance, reducing productivity and quality of life. It affects millions worldwide who spend several hours a day looking at screens.

• Eye Strain, resulting in discomfort, fatigue and difficulty keeping your eyes open.
• Headaches due to eye strain and neck pain. This also leads to difficulty concentrating.
• Neck and back pain as a result of poor posture while using digital devices for extended periods
• Temporary blurred vision
• Dry eyes can result from prolonged use of digital devices, leading to discomfort and irritation (watery, burning and/or itchy eyes).
• Sensitivity to light (photophobia).

Dry eyes can result from prolonged use of digital devices, leading to discomfort and irritation, such as watery, burning, and/or itchy eyes. Extended periods of screen time cause our blink rate to decrease significantly, reducing the natural lubrication and moisture of the eyes. Blinking is crucial as it helps distribute tears evenly across the eye surface, keeping them moist and free from dust and other irritants.

Moreover, the angle and distance at which we view our screens can also contribute to dry eyes. Looking downward at a screen causes our eyelids to partially close, reducing the blink rate and tear production.

In conclusion, prolonged digital device usage can lead to dry eyes due to a reduced blink rate and suboptimal viewing angles. Regular breaks, adjusting screen positioning, and using lubricating eye drops to alleviate dryness and discomfort are essential.

The duration of Computer Vision Syndrome symptoms can vary depending on the severity of the condition and the individual’s response to treatment. In most cases, taking regular breaks from prolonged screen time and following the above tips for preventing CVS can help relieve symptoms within a few days to a week.

However, if symptoms persist, it is important to consult an eye doctor to rule out any underlying vision problems contributing to the issue.

One of the lesser-discussed symptoms of menopause or perimenopause is the increased susceptibility to Computer Vision Syndrome (CVS) or Digital Eye Strain. As estrogen levels decline during menopause, women often face a reduction in tear production, leading to dry eyes. This dryness can exacerbate the symptoms of CVS, such as itching, burning, and blurred vision, especially in an era where digital screen usage is pervasive.

Furthermore, the age-related decrease in accommodation, or the eye’s ability to change its focus from distant to near objects, can intensify the strain experienced during prolonged screen time. Hormonal fluctuations during menopause also affect the eye’s meibomian glands, responsible for the oily layer of tears, further contributing to dry eye syndrome and discomfort.

Preventive measures, such as regular eye check-ups, lubricating eye drops, and following the 20-20-20 rule, can mitigate the risks.

Constant exposure to screens has given rise to Computer Vision Syndrome (CVS). CVS encompasses a range of eye and vision-related problems resulting from prolonged screen use. The high-energy visible (HEV) blue light emitted by digital devices can strain the eyes, leading to symptoms like dryness, redness, irritation, and blurred vision. The close proximity at which we view these screens and the often sub-optimal lighting conditions further exacerbate the strain.

Modern lifestyles, characterised by extended screen time, force the eyes to constantly focus and refocus as we switch between screens, read digital text, or engage in visually intensive tasks. Over time, this continuous effort can tire the eye muscles, leading to discomfort and potential long-term vision issues.

Computer vision syndrome (CVS) is not a disease or a permanent condition but rather a group of symptoms caused by prolonged use of digital devices such as computers, tablets, and smartphones. Therefore, CVS cannot be cured, but it can be managed and prevented.
Manage and prevent Computer Vision Syndrome (CVS) by adjusting your workspace, taking regular breaks, and using preservative-free drops and sprays.

Underlying vision problems such as nearsightedness, farsightedness, or astigmatism can also contribute to CVS, which can be treated with prescription glasses, contact lenses or laser eye surgery.
