“[Sugar], as well as sugary drinks, increase the risk of diabetic retinopathy, which if not controlled can lead to retinal detachment and visual loss,” the expert added.
Meat
While meat is a great source of protein, processed and raw versions could do more harm than good.
Dr Rabia said: “Processed meat is also one to keep an eye on, as it’s high in salt, which can cause hypertension-related retinopathy – a disease of the retina (back of the eye).
“Raw meat can cause toxoplasmosis, which if it affects the centre of the retina can cause a permanent scar that can ultimately lead to vision loss.
“Toxoplasma parasites are passed on to livestock, so if the meat is not cooked, the parasites are not killed and can be consumed by the person eating it.
