The lens of a dog's eyes is a solid state disk located in the center of the eye. It is located in the iris and is not usually seen as it is completely transparent, like glass. When light enters the eye, through the pupil and behind the eye, the lens is an important part of the eye. When its shape changes, we can see it at different distances.
When a dog grows older, changes happen inside the body. Maybe it has less energy, becomes a little fat, or may form a small arthritis, and there is a change in the eyes. Moreover, the core will continue to harden, and begin to become less transparent, and more "yin" parts appear. This hardening leads to turbidity. This is a gradual process that generally does not cause vision problems, which is called nuclear sclerosis.
Older dogs are more likely to develop cataracts than younger dogs, which may be because older dogs are exposed to more things over time, which can hurt their eyes. There are many causes of cataract formation, including radiation, damage, malnutrition, genetics, and diabetes, which can increase the risk of cataracts.
