> Macular degeneration, an incurable eye disease that results in significant vision loss starting on average in a person's 50s or 60s, is the death of photoreceptor cells in the retina. Those cells need molecules called retinal to sense light and trigger a cascade of signalling to the brain.

> To protect your eyes from the blue light, Karunarathne advises wearing sunglasses that can filter both UV and blue light outside and avoid looking at your cell phones or tablets in the dark.
