Based on your performance on this Optometry Board Part 1 Practice Test, you’re not yet ready for the NBEO® Part 1.
Keep your head up! Also, don’t focus on your estimated score, they mean essentially nothing at the start. Rarely does anyone start these exams and score well immediately, if that was the case then they wouldn’t even need to practice! These are ‘practice’ tests, meaning you’re practicing to improve your skills. If you continue to work hard and study, read and understand the solutions, practice with “OptometryBoards.com” daily and give it your best effort, we promise your score will improve. Review and learn for now, and the scores will come.

Question 10 of 15
10. Question
Your patient has an acquired Blue-yellow defect. Which one of the following will be the best diagnostic test?
CorrectC. Anomaloscope test. Anomaloscope is the only color vision test that can determine anomalous trichromats from dichromates. It is considered one of 2 accurate color vision tests we have in our toolbox, followed by the ishihara test.

Question 11 of 15
11. Question
What is the perceptual/developmental experience of fusion of dichoptic images with similar but contrast-reversed targets that fall on corresponding retinal loci?
CorrectA. Confusion. Occurs when very different images are formed simultaneously on corresponding retinal points in the two eyes. Diplopia occurs when different images are formed simultaneously on non-corresponding retinal points in the two eyes.
IncorrectA. Confusion. Occurs when very different images are formed simultaneously on corresponding retinal points in the two eyes. Diplopia occurs when different images are formed simultaneously on non-corresponding retinal points in the two eyes.

Question 13 of 15
13. Question
Visual acuity presented by grating patterns in different orientations is described as?
CorrectA. VA is the ability to identify the highest spatial frequency grating orientation. Meaning only one person can resolve dark and light bars.

Question 14 of 15
14. Question
What of the following would MOST benefit a patient with a high astigmatism?
CorrectC. Long pass filter. Long pass filters transmit only long wavelengths that result in only allowing transmission of “glare” causing wavelengths. AR coating mimics long pass filters
IncorrectC. Long pass filter. Long pass filters transmit only long wavelengths that result in only allowing transmission of “glare” causing wavelengths. AR coating mimics long pass filters

Question 15 of 15
15. Question
On the electromagnetic spectrum, which wavelength causes the MOST damage to the cornea?
CorrectD. 499-420 falls on the blue light spectrum lower half. This is shown to cause slight corneal damage with long term exposure. Hence why blue light adaptive lenses are currently used to help alleviate side effects caused by blue light.
