World Vision Month: your vision reflects your overall well-being

Johannesburg - March marks Vision Health Month, a global campaign dedicated to emphasising the importance of routine eye tests and proactive measures to safeguard your vision.

The benefits of an eye test extend well beyond ensuring clear sight. A comprehensive eye examination is more than a vision check - it serves as a valuable tool for assessing your overall health. Optometrists are often able to identify signs of systemic conditions long before noticeable symptoms arise.

Changes in vision or the presence of floaters can sometimes be the earliest signs of diabetes. Elevated blood sugar levels can damage the blood vessels in the retina, leading to diabetic retinopathy.

High blood pressure (hypertension) may cause changes in the blood vessels within the eyes, such as narrowing or bleeding, which could signal heart-related issues. Yellowish deposits on the eyelids (xanthelasma) or a white/grey ring around the cornea (arcus senilis) might indicate high cholesterol. Inflammation or dry eyes can be linked to autoimmune conditions like rheumatoid arthritis or lupus, while yellowing of the whites of the eyes (jaundice) often points to liver dysfunction.

Spec-Savers optometrist, Eela Makan, highlights: “The eyes offer a unique window into the body’s health. Routine eye tests not only detect vision-related problems but can also reveal signs of broader health conditions. Early detection is crucial for effectively managing and addressing these issues.”

The campaign encourages everyone to prioritise their eye health by scheduling regular tests. “Adults should undergo a professional eye test at least once every two years, or more often if advised. These visits are essential for detecting eye diseases such as glaucoma, which may develop without symptoms, and for identifying systemic conditions that could otherwise remain undiagnosed,” adds Makan.

Some conditions, like multiple sclerosis or a brain tumour, can manifest through symptoms such as vision loss or double vision. This was the case for Gqeberha resident Anna Lascelles, who discovered how life-saving a routine eye test could be. After undergoing a routine eye test, her Spec-Savers optometrist referred her to an ophthalmologist. Further investigations led to the diagnosis and successful treatment of a brain tumour. “An eye test saved my life,” shared Lascelles. “I would urge everyone to take that step—you never know what it might reveal.”

“Although this particular case is extraordinary,” notes Makan, “it underscores the critical role eye tests play in identifying serious health concerns.”

Beyond routine eye tests, Vision Health Month advocates adopting healthy lifestyle habits to protect your vision. These include maintaining a balanced diet, shielding your eyes from harmful UV rays, staying physically active, and avoiding digital eye strain.

Vision Health Month serves as a timely reminder to prioritise your eye health. Your eyes could hold the key to unveiling hidden health conditions and ensuring a healthier future.
