Online Depth Perception Test
Probably little: Congratulations on the 20/20 vision - is this in both eyes separately? If only in one eye, that could be the reason for the lowered depth perception. Some are born without the part of the brain wiring that makes depth perception. Generally loss of depth perception is not fixable but generally also is not a problem for most life activities. ...Read more
Separate functions: 20/20 refers to the acuity of vision, hopefully at this level in both of your eyes. Depth perception (stereovision) refers to a brain function in which the input from both eyes together is summed producing an image in depth. Some lack this part of the brain wiring but can see well otherwise. This may be true for you. ...Read more
At 3d shows, I notice the 3d effects maybe 2-3% of the time. The rest of the time, the picture looks the same with one or both eyes open. All the tests I've tried suggest stereoscopic vision/depth perception is fine ... so why can't I see 3d?
Apparently about 10%: of people can not see in 3D. Because humans have both eyes in front, the possibility of having them work together to create depth perception exists. The fusion in our brains of two slightly different pictures from each of our "cameras"/eyes gives the sense of three-dimensionality. Lazy eye and strabismus are conditions that interfere with eye coordination. It can be corrected, esp in children. ...Read more
Evaluate: Your ophthalmologist has tests for this. You can estimate your ability by seeing movies in depth like Avatar, or getting one of many books at the bookstore e.g. "Magic Eye" which require perception in depth to see in depth. ...Read more
Stereo vision issues: Stereovision is the ability to see in depth using the two eyes together. If one eye sees poorly or the eyes do not work well together, your depth vision is likely to be impaired. If this is your problem, you will notice this especially if you look at a stereovision movie like avatar when the experience will not be so well for you. ...Read more
Depth = 3D vision : Depth perception, or 3-d vision, can easily be tested by an ophthalmologist in the office. Any problems in depth perception arise from either one of the two eyes not seeing well, or the eyes are not aligned properly. An ophthalmologist can tell you which of the following can cause this problem in your child and how to treat it. ...Read more
When a good friend of mine lays down either on his back, or sides his depth perception goes haywire, and if he is reading, he can see the words, but does not comprehend what he is reading. It is just a bunch of words.
No: 3d glasses do not increase depth perception. They allow one to experience 3d vision from a flat screen when the image has been formatted for this. People who have poor 3d vision cannot see in 3d in any situation. 3d vision develops in early childhood and cannot be changed after this time. ...Read more
Binocular: True depth perception (stereopsis) is a function of the visible portion of the brain requiring input from both eyes. The ability to fuse the two eyes is inborn and a very strong reflex. It is a wonderful, almost magical function of a portion of the vision. There are many books with interesting pictures which requires true depth perception for them to work. ...Read more
Separate functions: Binocular clues involve the use of stereopsis which is true depth perceptions dependent upon using both eyes together (and is what you use when you see a 3-D movie). Monocular clues depend upon the catalog of image types and sizes so you know how far things are by these clues. Those who have lost one eye, depend upon monocular cues for depth understanding. ...Read more
No: Neither should fade in normal aging. Near vision does "fade" in a condition called presbyopia. Loss of peripheral vision is sometimes due to serious conditions such as a retinal detachment or glaucoma or retinitis pigmentosa. Depth perception problems can be due to lose of vision in one or both eyes. ...Read more
In monovision with contacts dr said my depth perception is lessened. How does this affect driving?
Is it common for people to start losing their peripheral vision and depth perception at the same time?
Decreases: Depth perception is partially dependent on the ability to fuse an image with both eyes (stereopsis). After an injury that takes the sight from one eye, this will decrease, but you can still use other visual cues for depth perception. ...Read more
Not too much: There is a center for stereoscopic vision in the brain. If defect you might have poor or no stereoscopic vision which is essential for depth perception. This also can be due to poor vision in one eye. From a practical standpoint, loss of this function is of minimal problem. You need excellent stereo vision to work as a watchmaker, or to be an excellent baseball player. Little else is affected ...Read more
Does coordination problems in a child have anything to do with a lack of depth perception from needing glasses?
Perhaps-let me see!!: Poor vision certainly is on the list of things to explore when a kid is "clumsy". It may be things other than depth perception that have to do with vision that can affect coordination, including blind spots, blurriness, unusual eye movements that can affect hand-foot-eye coordination. Any investigation of poor coordination should include at the very least an exam of the eyes and visual screening. ...Read more
I wear monovision contacts and lose some depth perception when driving. Is it possible to wear glasses over the contacts to improve this when driving?
Daughter15, diagnosed with chronic migraines not yet had mri. Feels burning and crawling under skin. Depth perception off. Could it be something else?
Early Fuchs dystrophy w/clear corneas, mild gutta, 20/20vision but high densitometry,glare, lights,depth perception. Dr says this combination unusual?
Re-calibration: A vitrectomy removes some of the vitreous humor from the eye. Light goes thru this and is refracted in a particular manner. After vitrectomy, the amount of vitreous is different and your eye, optic nerve and brain have to re-calibrate the incoming light information and the response to it from the brain. Change requires time for adaptation. ...Read more
