Warmer weather has settled over Johannesburg, and the stretched-out golden afternoons are once again pulling families toward sports grounds, garden patios, walking trails and weekend drives. In Bryanston, the practice of Dr. T Fletcher is treating this seasonal shift as a chance to flag something most people stop thinking about the moment the winter coats go into storage, namely that eyes deserve sun protection every bit as much as skin, and that the ultraviolet light which intensifies through the warmer months contributes to several of the eye conditions most frequently diagnosed in South Africa.
September lends itself to the reminder. The Highveld sky clears, the number of hours spent outside jumps, and whatever routines take hold now usually stick for the rest of summer. The trouble with ultraviolet exposure is that it accumulates quietly instead of announcing itself, and that is precisely why it slips under the radar. Because the eye’s surface never burns in a way you can feel, the toll of years of unshielded light shows up only long afterwards, as changes to the lens and to the ocular surface that a specialist can pick up during an examination.
Why Ultraviolet Light Matters to the Eye
South Africa occupies a region where the sun is fierce and the outdoor calendar runs long. That geographic reality drives the mix of eye conditions that local ophthalmologists encounter in practice, and it is the reason sun protection is framed as a daily health habit rather than something reserved for holidays. The practice website counts ultraviolet radiation among the acknowledged risk factors for cataracts, together with age, family history, diabetes, hypertension, obesity, smoking, alcohol, certain medications, eye inflammation or trauma, prior eye surgery and high myopia. Ultraviolet exposure likewise heads the risk list for pterygium, a growth on the surface of the eye that turns up more often in sunny climates and nearer the equator.
None of that is an argument for staying indoors. It simply means the attention paid to sunscreen, hats and shade ought to reach the eyes too, and that sunglasses are better thought of as protective gear than as a fashion touch. On this the practice website is precise, calling for sunglasses that block one hundred percent of ultraviolet rays. How dark the lens tint appears is not the deciding factor. A dark lens with no ultraviolet filtration simply lets the pupil relax and open wider, which is exactly the wrong outcome.
Pterygium and the Outdoor Season
Few conditions show as plainly as pterygium how sunlight, wind and dust work on the eye’s surface over the years. The practice characterises it as a noncancerous lesion that tends to grow slowly across a lifetime, and it names prolonged ultraviolet exposure, dry eye, and irritants like dust and wind among the causes. It frequently surfaces in adults aged twenty to forty, dropping it right into the busiest chapter of work and family life, when eye complaints are the first thing to be brushed aside.
Among the symptoms listed on the site are burning, a gritty feeling, itching, the sense of something lodged in the eye, and blurred vision. In some people it shows up chiefly as redness and inflammation and little more. When the growth spreads onto the cornea it can warp that surface, bringing on astigmatism and the visual disturbance that follows. Treatment might use lubricants or steroid containing drops to ease symptoms, while surgical removal comes into play where the growth advances and fails to respond to medication. Spring is a sound moment to have ongoing redness or irritation looked at rather than kept in check indefinitely with over-the-counter drops, since it is the pattern of symptoms that steers you toward the real cause.
Cataracts, Glare and the Longer View
The practice website names cataracts as the leading cause of visual loss. They develop in the eye’s natural lens behind the iris and pupil, dimming vision and frequently throwing off glare by day or by night. That glare is usually the first thing people register as daylight stretches out, be it a windscreen that abruptly seems tougher to see through in the late afternoon, or headlights that seem to scatter more than they once did on the way home.
The site lays out the recognised types, among them nuclear sclerosis at the centre of the lens, cortical cataracts that form around the edge in a spoke-like pattern, and posterior subcapsular cataracts on the lens’s back surface. It also addresses what is known about prevention, highlighting foods rich in antioxidants such as omega-3 fatty acids, lutein and zeaxanthin from vegetables, and vitamins E and C, alongside proper ultraviolet protection. When surgery is called for, the practice describes cataract surgery as a minor procedure and the most common elective one, entailing removal of the clouded lens and its replacement with 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 offered as well. The conditions detailed on the practice website span cataracts, flashes and floaters, pterygium, age-related macular degeneration and glaucoma, which between them make up a large portion of the reasons adults are referred to an ophthalmologist in Johannesburg.
Her path started 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, took on an honorary consultant role at Helen Joseph Hospital, and spent a period in private practice as a locum before launching her own practice in 2014. She belongs to 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, which is a big 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, which cuts the light coming at the eye from overhead and from the side. Extend the same protection to children that adults receive, because outdoor hours in childhood feed into lifetime exposure. Keep the eyes 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 ease, and get them checked rather than holding out for them to worsen.
Scheduling an examination when nothing feels pressing is also when a specialist has the most to draw on. Glaucoma especially tends to progress with no early warning signs, which is why an eye examination looks past whatever prompted the visit. Selecting an opthalmologist for that check means it is done by a doctor trained in both the medical and the surgical care of eye disease.
