Could 3d glasses enhance your depth perception?

Could 3d glasses enhance your depth perception?

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

Might mirrors affect self perception?

Mirrors are reality: Mirrors certainly reflect the self in the most accurate sense in the same way a scale reflects weight. If you mean do mirrors have a negative effect on self perception, the answer would be no - its the thoughts that come along with the perception that can be distorted, helpful, or harmful to oneself. ...Read more

Would hppd (hallucinogen persisting perception disorder) be a result of evolution?

Would hppd (hallucinogen persisting perception disorder) be a result of evolution?

HPPD: Hallucinogen Persisting Perception Disorder is produced by the chronic use of hallucinogens, like LSD, ecstasy, MDMA. These substances affect the perceptual fields (visual, auditory, gustatory, olfactory, tactile) perdurably. Therefore may have hallucinations when not intoxicated. For HPPD, the symptoms are solely due to drug use, not to schizophrenia or other psychosis or mental condition. ...Read more

What can you tell me about monocular and binocular cues for depth perception?

What can you tell me about monocular and binocular cues for depth perception?

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

How can you measure visual acuity w/ the snellen eye chart?

How can you measure visual acuity w/ the snellen eye chart?

Read smallest line: The snellen chart is a graded series of letters or numbers smaller as you go down. The uncorrected vision is the smallest line easily read with each eye. Your ophthalmologist will present you with lenses to improve the level of the smallest line to hopefully get you to 20/20 - the standard of normal. It is a subjective test requiring your active input. ...Read more

Will visual acuity always determine eyeglass prescription?

Will visual acuity always determine eyeglass prescription?

No, not always: Visual acuity is a measure of how well you see. In most cases this reflects on what your prescription might be but it can't estimate it exactly. There are many other factors that determine how well you see: if your retina is healthy and if there are other problems with your cornea or lens. It's possible to have poor visual acuity and yet have no need for glasses. ...Read more

Visual acuity. CC: OD 20/25-2 ... OS 20/30-2 ... intraocular pressure OD 21 OS 18 ...any interpretation or explanation for theses eye vision results?

Eye Exam: CC means with correct, like glasses or contact lenses. OD, right eye. OS, left eye. 20/25-2 means that you missed 2 letters on the 20/25 line on the vision chart. Intraocular pressure is the pressure inside your eyeball that keeps it from collapsing, similar to air pressure in your car tires. It is reported in mm Hg. Statistical normal is between 8 and 23. ...Read more

What to do if I failed depth perception test but have 20/20 vison?

What to do if I failed depth perception test but have 20/20 vison?

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

What does it mean if I have failed depth perception test but have 20/20 vision?

What does it mean if I have failed depth perception test but have 20/20 vision?

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

What does it mean when your depth perception is poor?

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

Can you tell me about depth perception problems in children?

Can you tell me about depth perception problems in children?

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

Hi doctors, was just wondering what is depth perception related to--where does it come from?

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

Can mono-vision cause problems with driving at night or problems with depth perception.?

Yes: Mono vision depending on the disparity in vision between the two eyes can be a definite cause ifa drop in depth perception. You can test this put by comparing with contacts vs glasses by taking the stereo fly test. You might be under corrected and this is causing night myopia. ...Read more

Is it common for peripheral vision and depth perception to start fading at almost the same time?

Is it common for peripheral vision and depth perception to start fading at almost the same time?

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

My doctor said I have very little depth perception, what does this mean?

My doctor said I have very little depth perception, what does this mean?

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
