<p>My son who has never had a vision problem had his vision screening today. He came home and said he had failed a "portion" of the color screening. What does this mean? He has never had any visual problems or history of any color deficiancies. Does this mean he is no longer is a potential ''phlebe"?</p>
<p>there are alternate colors tests he can take. don't give up just yet. have him call DODMERB in Colorado Springs and see what he can do about getting a waiver/ retest.</p>
<p>You need good color vision for being a deckie. There’s rumor that if your going engineer you can get a wavier if color vision does become an issue. Talk to your eye doctor/DoDMERB. If he took the test with the lights there’s a lot of really tight rules with is and people saying the right color of the lights. ie. red looks pink, white looks yellow etc, but you have to say red or white or else you fail. He might just need a retest. </p>
<p>Good luck, don't give up yet.</p>
<p>Color blindness is a disqualifying condition....I have seen several people sent home during Indoc for being color blind. Unless things have changed which I doubt. </p>
<p>The Farnswerth Lantern test is the ultimate decider most of the times. The Ishihara colored plates (the ones with the numbers) can be a beast for some.</p>
<p>The Farnsworth Lantern has been used since Dean Farnsworth first described it in 1946 for the testing the color signal discrimination ability of color anomalous individuals. This test has found longstanding application in the military and the transportation industry to qualify operators of ships vehicles and aircraft that are known to have failed screening tests such as the Ishhara plates. Because many color deficient persons do have reasonably good signal light discrimination Farnsworth Lantern Test often enables the qualification of these individuals.</p>
<p>I have had to take the Farnsworth test, it was the only test that I could pass for my ticket (200T), I have a sever red green deficency. The school will have tougher standards, you should check with the Admissions Office. You do not want your son or daughter to have to gear up and go thru the Indoc only to be sent home. Remember that the USCG sets the standards for license requirements.</p>
