NS is a 10-year-old shy child who came to our office for a consultation reported as ‘blurry vision in one eye’. His mother searched online and learned about myopia, also known as nearsightedness. She was told by a previous eye doctor that her son did not need to wear glasses since he said he was ‘seeing well’ last year. However, in early February NS started complaining his right eye was getting tired easily and he could hardly concentrate well when he was reading or doing near work. NS enjoys playing robotic games on the computer at leisure, yet he said he could no longer play as much as he used to without eye strain. His mom was concerned about the rapid change of his vision and discomfort he experiences. As she did more in-depth research about myopia, she found out about the unique ‘myopia control service’ offered by Treehouse Eyes on Google.

Interestingly, neither parent has vision issues or need for glasses. Upon evaluation, I found that NS has a significant amount of myopia in the right eye while his left eye displayed mild hyperopia and astigmatism. This condition is generally known as ‘antimetropia’ in which the shape and prescription is distinctively different in each eye. Given the fact that he was not prescribed with glasses last year, it was assumed that the level of myopia at that time might have been miniscule or considered ‘asymptomatic’. The onset of myopia often begins with a low amount which can often go undetected. If left untreated, however, myopia can suddenly spike up and result in noticeable blurry vision at distance. The case of NS raised suspicion of ‘lazy eye’ or amblyopia due to the distinct anatomical and optical differences between the two eyes. Fortunately, he can be corrected to 20/20 with no indication of lazy eye.

Upon extensive education and discussion with NS and his mother, I recommended an individualized myopia control treatment for NS via using K.I.D.S. (Keratometric Induced Dioptric Steepening) overnight contact lens for the right eye to slow or halt myopia progression at this time. The untreated left eye would be monitored closely to ensure that it would not develop myopia in the long run.

After the first day of overnight lens wear, NS’s unaided vision in the right eye was 20/20-. He noticed that not only has his distance vision improved significantly after just one night of wearing the lens, he also reported that he can read more comfortably with little stress. His mother was amazed about the great result in such a short period of time, and both of us were grateful to witness her shy kid who initially hid behind his mother’s back finally showing a grin and become more relaxed after knowing that he can see much better than before.
