How Do You Handle Visual Information Overload?

Have you ever experienced information overload…on your eyes? There is a real condition called Load-Induced Blindness that occurs when you have too much visual information coming at you. A new study showed that when you are faced with a lot of visual data at once, your ability to see critical information is reduced – similar to what happens when there are lower light levels on an image you need to detect.

The study included volunteers with normal vision who completed a sensory memory task involving colors, positions and line orientations on rapidly flashing squares. In high load situations (lots of visual data), participants were only able to accurately spot line orientation in 64% of the images; in low load situations, that percentage went up to 95%. In the high load situations, participants needed 50% more light contrast to increase accuracy.

The bottom line is that too much visual information at one time may cause you to miss important things. Add into the mix that your vision is impaired with nearsightedness, farsightedness or astigmatism and you may have an even more difficult time at distinguishing important images during attention-demanding situations (although this was not specifically included in the study).

Having LASIK in Charleston to correct vision problems will not change how your brain processes high loads of visual information, but it may allow you to see without the need for corrective lenses (glasses or contact lenses)…removing one more barrier to seeing clearly. LASIK has changed the lives of many of our patients at Charleston Cornea & Refractive Surgery, allowing them to work, play and parent with visual freedom.
