What's Inside

  • Polish surgeon restores Ukrainian's vision on Christmas Day
  • Blind people suffer worse from pandemic related anxiety and depression
  • Side effects of losing one's vision

  • And, about ten more stories about the science, medicine and prevention of blindness from all over the world

Editorial by Chris Hofstader

If you've been following our science digest from its start over on my personal site, you'll notice that we've changed its name. It's now called "Science Briefs" but, although this is the first edition under this name, we kept the edition numbers consecutive to avoid confusion.

This edition has about a dozen articles about the science and medicine related to blindness and covers a pretty wide range of stories. This week, my personal preference was for the articles written for the lay person as some of the others are pretty dense with vocabulary I find difficult. We hope that those of you who understand science enjoy all of the articles and those of you who are less likely to understand the vocabulary of ophthalmology will enjoy those that I did. The article on myths related to Masturbation is pretty entertaining.


World Blind herald does not write the stories to which we link in Science Briefs, we gather them, curate them and bring them to our readers. We are not scientists ourselves and cannot guarantee the validity of the stories in this digest. We do, however, want to be very clear that you should not attempt any of the medical interventions mentioned in Science Briefs without first consulting a professional ophthalmologist and discussing it with them first. Do not take medical advice from this or any other web site, podcast without first consulting a professional.
