The delicate structure of your dog's eyes makes them vulnerable to numerous diseases and injuries. A dog's eye has a third eyelid (nictitating membrane) that helps cleanse and lubricate the eye like a windshield wiper. But sometimes the third eyelid's tear gland protrudes outward, appearing as a bright red bulge in the inside corner of the dog's eye also known as "cherry eye". Surgery for cherry eye usually involves repositioning the gland. Corneal damage often causes eye redness. And dogs may also paw at their eyes because of discomfort. Once at your veterinarians, the eye examination includes a check for corneal damage by applying a special stain to your dog's eye. You can also use Lubrifair Lubricant Eye Drops which is used to prevent further irritation and to relieve dryness of the eye. The lens of the eye is also subject to disease. Surprisingly, inherited cataracts usually occur in your animals, although some dogs suffer from late-onset inherited cataracts. In general, older dogs are not as responsive to visual stimuli as younger dogs. Other common diseases of the eye include redness, cloudiness, excessive tearing, eyeball swelling, pain, and sensitivity to light. Crystal eye tear stain remover can be used to wipe tears from your dog’s fur and other stains as well. Common sense is the soundest strategy for preventing eye problems. Always keep your dog head inside moving vehicles, check your dog's eyes on a regular basis, and make sure its annual veterinary checkup includes a thorough eye examination. Despite an owner's best efforts to head off eye problems, some dogs do go blind - often very gradually. The dog's lateral eye placement allows better wide-angle vision but hinders depth perception and close-up viewing because there is minimal visual overlap (binocular convergence) between the two eyes. The structure of the dog's retina helps explain other idiosyncrasies of canine vision. The tapetum reflects light back through the retina, giving the retina a second opportunity to absorb light.
