because you focus your eyes for a long time
Stereogram optical illusions require your brain to combine two slightly different images to perceive depth. If you have difficulty seeing them, it may be due to a lack of experience with focusing techniques, misalignment of your eyes, or even certain visual processing issues. Additionally, some people may have trouble relaxing their eye muscles or may not have the necessary visual acuity to perceive the hidden images. Practice and adjusting your viewing technique can sometimes help improve your ability to see stereograms.
Well, no. Although optical illusions can distort your vision somewhat, they cannot permanently damage your eyes. If you have had eye problems in the past, though, you may want to be wary of optical illusions. ~
Alcohol doesn't even kill brain cells, so a few swirly patterns certainly won't. The worst that can happen to you is eye strain.

Optical Character Recognition. Essentially, OCR technology enables computers to "read" text within images. This process converts images of typed, printed, or even handwritten text into machine-readable text data. This data can then be edited, searched, and used in other software applications.
Theyre not. My balls are even more awesome.
Lenses are used in many modern day optical devices ... in order to understand howthese devices work, a person must have sufficient knowledge about lenses, even ifthat person doesn't need eyeglasses ...
No of course not. I dont think theyre even in a relationship :S
A common optical illusion caused by atmospheric conditions is a mirage. A mirage occurs when light is refracted as it passes through air layers of different temperatures, creating a false image of distant objects, often seen as water on a road or desert. This phenomenon is a result of the bending of light rays, which can distort our perception of reality.
Because they aren't completely over you... even if they have a new love interest... it doesn't matter. theyre trying to hurt you because theyre hurting over the break up
Optical receptors are complex apparatus used in the detection of tumors or HIV, for instance. There are even optical receptors that are used in the process of aging Scotch whiskey. Laboratories and hospitals would be the place to find optical receptors, but equipment like this is not sold to the public.
