Cheryl G. Murphy is an optometrist whose passion for vision science and the eye began as an research assistant in undergraduate school at SUNY Albany, where she studied the development of the visual cortex in the brain. She then attended SUNY College of Optometry where she again assisted in vision research, this time on chromatic aberration and its effect on accommodation of the eye. She attained her bachelor of science degree in biology from SUNY Albany in 2000 and her doctor of optometry degree from SUNY Optometry in Manhattan in 2004.
Murphy began her blog, Science Hidden in Plain Sight, in 2008 and now enjoys freelance writing for Scientific American magazine’s guest blog and several optometric trade magazines including Review of Optometry, 20/20 magazine and Review of Optometric Business. She is always looking for more opportunities to write and for ways to share the awesomeness of Science Hidden in Plain Sight with the world. Dr. Murphy practices optometry on Long Island, N.Y., where she resides with her husband and five-year-old triplets.

침대에 자리를 잡고 누워서 눈을 감는다. 잠을 청하려는데, 분명 눈을 감았는데 자꾸 이상한 게 보인다. 반짝반짝. 가끔은 소용돌이치듯이 무슨 이상한 패턴이 자꾸 보이는 것만 같다. 어릴 적에는 내 눈이 다른 사람과는 조금 다르다고 생각한 적도 있을 수 있다.
