So, the dog is man's best friend-even the interesting thing is that, although we depend on our dog pets to see for those who don't; to protect us against those who want to hurt us; and know who are the owners and love them unconditionally, just a few of us really know what it is, you actually see on the day.
For people who take their pets with their families and the lives it is almost unbelievable, we answer a broader interest to know what and how the world sees our pets, and how that differs from the human world, optical. Note these differences can help people better understand, love, and show their furry friends.
While the dogs can't see as much detail as the people, their field of vision will be wider because of the location of their eyes. Therefore, although your dog may not pay attention to detail, that a human friend, your dog will be able to detect an intruder much earlier than you. In addition, dogs are ultra-sensitive moving objects (and the movement in General) and so will direct any movement of a mile away-that's exactly what makes them so invaluable aid for the blind and a great search and rescue members (not to mention the hunters in the North of Serbia). It is necessary to add that the dogs could be considered far-sighted their close-up vision is much worse than, and do not have and cannot focus on the close and generally will see things as blurry. Also do not have a correct perception of depth.
Another interesting fact is that, while the dogs do not have a clear vision, their night vision is much better than the man. As we head into the optician for glasses wearing night-like when running, the dog becomes even better watch-dog as the Sun.
It is interesting to contrast for man, one know that the dog, which becomes generally blind to his new status as the least powerful of the five senses, smell and sound are the two most powerful. As well as people who are blind will need time to adjust, so also will the dog-it's just so much faster than their human masters. The striking similarities between dogs and people can both note: after the failure of the eye as one of the downsides to the aging process.
The myth has been in circulation for years that dogs are completely color blind and cannot see or distinguish colors at all. The study disproved years this theory and shows that as people (mostly men) may be colorblind and still reveal some colors, so you can dogs. Canines red and Orange are generally only two indistinguishable color, while the blue and yellow are the most recognizable. Today, would describe the dog as red green color blind.
Like people, dogs also faces possible host problems with eye and conditions-including cataract, pink eye, glaucoma, dry eye, tumors and infections-just to name a few. In addition, just as people need to visit their eye doctors, when it seems that the disease of the eye to waylay; Why should they see to it that their dogs will have the same right. Sure signs that are for veterinary visit include, rubbing his eyes, avoid light and rubbing their faces to the ground. Excess tears or red eyes are the other tip of the compromise.
Where can we find solutions for optical problems, the nature of the dog is to adapt and the other senses as compensation. Finally, probably the biggest difference between the Visual capabilities of humans and canines, where people have simple solutions, visit your eye doctor, update their glasses prescription and if you choose to buy glasses, which corrects their Visual inefficiencies, the same is not available for dogs.
