The Eye and Vision Defects

Unlock the full lesson!

Learn about the structure and function of the human eye. I explain how the eye adapts to bright and dim light conditions as well as the process of accommodation for near and far objects. I then explain the reasoning behind short and long sightedness and how glasses correct for these vision defects before looking a newer technologies that help correct vision defects (contact lenses, laser eye surgery and lens replacements). Throughout the lesson we tackle past exam questions and I provide plenty of activities (match-ups, gap fills etc.) in the workbook as well as clear summary tables too.
