Protecting Sight #305: Are we running out of clean water? Anterior chamber depth, visual hallucinations, & writing about the arts.

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, podcast, or significant work.

Here is today’s list:

1. Ted Talk – Balsher Singh Sidhu: Are we running out of clean water? “Despite water covering 71% of the planet’s surface, more than half the world’s population endures extreme water scarcity for at least one month a year. Current estimates predict that by 2040, up to 20 more countries could be experiencing water shortages. These statistics raise a startling question: is the Earth running out of clean water? Balsher Singh Sidhu takes a closer look at water consumption. [Directed by Kozmonot Animation Studio, narrated by Addison Anderson, music by Deniz Dogancay].” (

The concept of clean water has bothered me for many years, increasingly so from visiting family in India. We take clean water for granted in many parts of the US. Recent crises in Flint, Michigan and shortages in California highlight the challenges of this most precious resource. A fast-paced Ted Talk which is worth watching again.

2. Cataract Surgery – Uday Devgan MD – 1073: Why did the AC Depth increase?

3. Andrew Lee MD – Visual Hallucinations.

Dr. Lee’s 450+ neuro-ophthalmology reviews are around 5 minutes each. Perfect for the busy clinician & trainee. I plan to watch one a day, from oldest to newest.

4. William Zinsser, On Writing Well: The Classic Guide to Writing Nonfiction. Chapter 18, “Writing About the Arts: Critics and Columnists.”
