Dr. T Fletcher Warns of Spring Sun Risks to Eye Health

The arrival of spring in Johannesburg brings back those stretched-out, sunlit afternoons that pull families outdoors again, onto sports fields, patios, hiking trails and the open road. Dr. T Fletcher's practice in Bryanston is seizing the seasonal shift to underline something that slips from view the moment the winter coats go into storage: eyes require sun protection every bit as much as skin does, and the ultraviolet light that intensifies with the warmer months contributes to several of the eye conditions most frequently encountered in South Africa.

There is no better time than September to drive the point home. The Highveld skies open up, hours spent outside rise steeply, and whatever habits take root now tend to hold across the entire summer. What makes ultraviolet exposure so simple to disregard is that it builds up quietly rather than striking all at once. Because the eye's surface shows no sunburn to sound an alarm, the toll of years spent in unprotected sunlight surfaces only much later, as changes in the lens and on the ocular surface that a specialist can pick up during an examination.

Why Ultraviolet Light Matters to the Eye

South Africa lies in a region where the sun is fierce and the outdoor season stretches long. That geography moulds the range of eye conditions that ophthalmologists encounter in local practice, and it explains why sun protection is regarded here as a daily health measure and not merely a holiday consideration. Among the acknowledged risk factors for cataracts, the practice website names ultraviolet radiation, together with age, family history, diabetes, hypertension, obesity, smoking, alcohol, certain medications, eye inflammation or trauma, previous eye surgery and high myopia. Ultraviolet exposure also heads the list of risks for pterygium, a growth on the eye's surface that becomes more common in sunny regions and nearer the equator.

Nobody is suggesting that outdoor time should be given up. The message is that the attention already paid to sunscreen, hats and shade ought to reach the eyes too, and that a pair of sunglasses is best thought of as protective gear rather than a fashion piece. On this the practice website is precise, calling for sunglasses that block one hundred percent of ultraviolet rays. How dark the tint appears is not the yardstick. A dark lens that lacks ultraviolet filtration simply lets the pupil open more comfortably and widely, which is the very last thing you want.

Pterygium and the Outdoor Season

Few conditions show as plainly as pterygium how sunlight, wind and dust act on the eye's surface over the years. The practice characterises it as a noncancerous lesion that tends to grow slowly across a lifetime, listing prolonged ultraviolet exposure, dry eye, and irritants like dust and wind among its causes. It frequently shows up in adults aged twenty to forty, catching people right at the busiest point of working and family life, precisely when eye symptoms are easiest to brush aside.

The symptoms the site records take in burning, a gritty sensation, itching, the feeling of a foreign body in the eye, and blurred vision. In some instances redness and inflammation dominate with little else to show. Should the growth spread onto the cornea, it can warp the shape of that surface, bringing on astigmatism and the visual disturbance that follows. Treatment might rely on lubricants or steroid containing drops to ease symptoms, with surgical removal reserved for cases that progress and fail to respond to medication. Spring is a sound moment to have lingering redness or irritation examined rather than managed endlessly with over-the-counter drops, since it is the pattern of symptoms that steers attention towards the underlying cause.

Cataracts, Glare and the Longer View

The practice website identifies cataracts as the leading cause of visual loss. They develop in the eye's natural lens, sitting behind the iris and pupil, diminishing vision and frequently causing glare by day or by night. That glare is usually the first thing people register as the days grow longer, be it a windscreen that abruptly becomes harder to see through in the late afternoon, or headlights that seem to scatter more than they once did on the way home.

The site outlines the recognised types, among them nuclear sclerosis at the lens centre, cortical cataracts forming in a spoke-like pattern around the edge, and posterior subcapsular cataracts at the lens's back surface. It also addresses what is known about prevention, highlighting antioxidant-rich foods such as omega-3 fatty acids, lutein and zeaxanthin drawn from vegetables, and vitamins E and C, alongside proper ultraviolet protection. When surgery is called for, the practice presents cataract surgery as a minor and the most common elective procedure, in which the clouded lens is taken out and swapped for an intraocular lens.

A Practice Built Around Specialised Care

Dr. Taryn Fletcher is an ophthalmic surgeon whose practice concentrates on microincision cataract surgery, glaucoma and medical retinal disease, with aesthetic work available as well. The conditions addressed on the practice website span cataracts, flashes and floaters, pterygium, age-related macular degeneration and glaucoma, which between them make up a substantial portion of the reasons adults are referred to an ophthalmologist in Johannesburg.

Her path began with a Bachelor degree of Medicine and Surgery from the University of the Witwatersrand in 2005. She served as a medical officer at St John Eye in 2008, qualified as an ophthalmologist in 2013, held an honorary consultant post at Helen Joseph Hospital, and worked in private practice as a locum before establishing her own practice in 2014. Her memberships include the South African Medical Association, the Ophthalmological Society of South Africa, the European Glaucoma Society and the European Society of Cataract and Refractive Surgeons, and she is registered with the Health Professions Council of South Africa.

Practical Steps for the Months Ahead

The steps that count through spring and summer are ordinary ones, which is a large part of why they get overlooked. Put on sunglasses that carry full ultraviolet protection, and keep them on in the car as much as on the field. Reach for a wide brimmed hat as well, since it cuts the light reaching the eye from overhead and from the side. Extend the same protection you give yourself to children, because outdoor hours in childhood feed into a lifetime of exposure. Keep the eyes well lubricated in the dry, windy conditions of the Highveld. Pay attention to fresh glare, shifts in night vision, stubborn redness, or a gritty feeling that will not settle, and have them looked at rather than waiting for them to deteriorate.

Scheduling an examination while nothing feels pressing is also when a specialist has the most to go on. Glaucoma above all tends to advance without any early warning, which is why an eye examination reaches past the reason a patient came in. Selecting an opthalmologist for that assessment ensures the examination is performed by a doctor trained in both the medical and the surgical management of eye disease.
