The eye is one of the most remarkable achievements of evolution, and has evolved up to 40 times in different parts of the animal kingdom. In humans, vision is the most important sense, and much of the brain is given over to the processing of visual information. In this Very Short Introduction, Michael Land describes the evolution of vision and the variety of eyes found in both humans and animals. He explores the evolution of colour vision in primates and the workings of the human eye, to consider how that contributes to our visual ability. He explains how we see in three dimensions and the basic principles of visual perception, including our impressive capacity for pattern recognition and the ability of vision to guide action.

This book examines the impact of climate change on eye disease and eye health. Filling a lacuna in the existing literature, Scott Fraser takes a deep dive into the eye diseases that are most affected by the climate crisis and explores the subsequent burden on organisations, charities and healthcare systems. Fraser begins by including short primer chapters on the basics of climate science and climate change, highlighting which environmental mechanisms directly and indirectly affect our health and why. He then looks in detail at the direct and indirect threats to eye health from climate change and examines factors including changing insect vectors, trauma from extreme weather events such as wildfires, floods and droughts, as well as the impact of crop failure, malnutrition, animal and plant migration. Highlighting the Global North vs South divide, the book goes on to consider issues around eye care, exploring the increased burden that climate-induced chronic eye diseases including cataracts, macular degeneration and nutritional eye diseases are placing on health care systems. These chapters also reflect on the ways in which eye care, ophthalmology, optometry, pharmaceutical and medical device companies all contribute to the climate footprint themselves. Unique and timely, this book will be a great resource for students and clinicians of ophthalmology, optometry and allied eye care professions, as well as climate scientists, researchers, policy makers, charities, NGOs working in related fields of environment and health.
"I am not going to let my blindness build a brick wall around me. I'd give my eyes one hundred times again to have the chance to do what I have done, and what I can still do."-Brad Snyder speaking with First Lady Michelle Obama On the night Osama bin Laden was killed, US Navy Lieutenant Brad Snyder was serving in Afghanistan as an Explosive Ordnance Disposal officer with SEAL Team Ten. When he learned of SEAL Team Six's heroics across the Pakistani border, Brad was thankful. Still, he knew that his dangerous combat deployment would continue. Less than five months later, Brad was engulfed by darkness after a massive blast caused by an enemy improvised explosive device. Suddenly Brad was blind, with vivid dreams serving as painful nightly reminders of his sacrifice. Exactly one year after losing his sight, Brad heard thousands cheer as he stood on a podium in London. Incredibly, Brad had just won a gold medal in swimming at the 2012 Paralympic Games. Fire in My Eyes is the astonishing true story of a wounded veteran who refused to give up. Lieutenant Brad Snyder did not let blindness build a wall around him-through tenacity and courage, he tore it down.
