Nuclear Sclerosis In Dogs

Understanding the “Cloudy Eyes” of Aging

What Is Nuclear Sclerosis?

Nuclear sclerosis is a normal age-related change that occurs in the lenses of dogs as they get older, typically beginning around 7-10 years of age. As new lens fibers form throughout life, older fibers become compressed in the center of the lens (the nucleus), causing it to appear blue-gray or cloudy. 

Unlike cataracts, nuclear sclerosis does not significantly impair vision. It does make it more challenging to see things up close and reduces depth perception.

  • Your dog continues to navigate relatively normally

  • Many owners first notice the change in bright sunlight or in photographs
