The eye as a window into your pain tolerance
Have you ever wondered why some people can swim for hours in a cold lake while others don’t last a minute? Everyone has a different tolerance for cold water, in much the same way that everyone processes pain differently. While an optometrist, Emmanuel Alabi, now a doctoral candidate in Waterloo’s School of Optometry and Vision Science, noticed it’s hard to predict how patients will handle the discomfort of routine medical procedures. That’s why he’s researching how the eye can be used as an objective measure of pain.
