Do your exercise!
Members of the Clear Vision Lab (Dr. Joshua Chu-Tan, Max Kirkby and Associate Professor Riccardo Natoli) have recently published a major review article highlighting the benefits of exercise to the brain but specifically your retina and vision. The paper was published in Clinical and Experimental Ophthalmology, the official journal of the Royal Australian and New Zealand College of Ophthalmologists.
The work has gained a lot of media attention and has been featured all across the country including a segment on Sunrise: https://7news.com.au/sunrise/on-the-show/scientists-developing-exercise-in-a-pill-c-4764457
