The next time you stumble across a starfish while swimming
in the ocean, gaze into his arms to see if he notices you. That’s right…his
arms!
Oddly enough, most starfish have primitive compound eyes on the
tips of each of their arms. A recent study showed demonstrated
that starfish use these eyes to process visual information, especially when
there was a need to locate food sources. Two groups of starfish were studied:
one group with eyes and one group without. The two groups were placed in a
sandy area of the ocean and studied how they moved toward the coral reef, which
was their food source. The group with eyes was able to navigate directly toward
the reef, while the group without eyes wandered aimlessly.
Additional studies into starfish may help researchers learn
more about eye evolution.
Researchers are also continually studying human eyes and
devising new technologies to correct vision problems. For example, in the past
if you were nearsighted, farsighted or had astigmatism, you were stuck wearing
glasses or contact lenses for life. Today, people have options, such as LASIK laser
vision correction, to potentially eliminate their need for corrective lenses.
That means swimming in the ocean (and checking out the
starfish) with clear vision using just a regular snorkel/diving mask or
goggles.
If seeing starfish and other sea creatures more clearly
sounds attractive to you, contact Wright Vision Center at 877-576-0202 or wrightvisioncenter.com today
to schedule your free LASIK Consultation. Dr. Wright isn’t an expert on
starfish, but he has extensive experience in helping qualified candidates
improve their vision.
