Severe corneal disease caused by dry eye or chronic keratitis, dense cataracts, and retinal detachment are some causes of dog blindness. If you suspect vision loss, take your dog to a vet as it could be due to age-related changes. Eyesight cannot be maintained just by applying substances to the eyes, as vision loss is usually due to a biological process.

While there isn't an eye test similar to what humans undergo, there are some vision tests conducted at the vet's office. These include tracking a laser pointer or cotton balls, and checking pupil reactivity to bright light.

Eyedrops can be used if prescribed by a vet. Buying over-the-counter eyedrops from local stores without a vet's approval is discouraged. It is important to examine the dog's eyes to determine the appropriate treatment.
