What is the perception of depth?
The perception of depth is the ability of the human eye to be seen in three dimensions. It is often proven by measuring length, width and height. For example, it is easy to recognize that the picture is photographs because cameras do not have accurate depth perception. Therefore, when we take a picture, we know that the person shown in the picture does not have a vase growing out of her head, but the resulting photo causes it to do so. Optical illusions, such as this, illustrate, as our minds perceive visual images that send our eyes to our brains.
People have a type of vision that is described as stereoscopic. The term stereoscopic comes from the Greek word stereos , which means solid. Each eye sees an image that is separated from the picture that has seen the other eye. The brain processes images and combines them in the final image of the visible brain. The perception of the depth of the eyes is determined according to how well the two eyes work separately and how they work together to make internally -preliminary images. It can be changed by changes in both eye.
One way to measure, one sees the world is through the perception of depth. This test measures how you interpret binocular allusions. These tests also measure the perception of the monocular depth or, as you can see the world looking for only one eye. From these stimuli, it allows people to see and estimate distances is the ability of both eyes to focus on one object, the ability of the eyes to simply concentrate and the ability to recognize shapes and size. These call the brain where objects are in relation to other objects.
Not everyone sees optimally. People suffering from amblyopia, hypoplasia of optical nerve and strabismus often have a perception of depth. A person with a single eye or a person missing one eye may not be able to find out where the objects are in relation to others. Visual therapy can help improve these problems.
The perception of depth plays an important role in many activities. Driving, sewing, threading needles, watching 3D moviesAnd even walking on uneven soil, all requires some levels of deep sharpness. Lidé bez fungování stereoskopického vidění nemusí být schopni tyto činnosti vykonávat nebo s nimi mohou bojovat. If you suspect a vision problem, talk to a licensed ophthalmologist or optometrist about testing your vision and the possibility of repairing or customizing your visions.
