Myopia, commonly called shortsightedness, is a condition in which light is focussed in front of the retina, resulting in blurred vision. Refractive surgery can reduce or even eliminate your need for glasses or contacts. The most common procedures are performed with an excimer laser.
Myopia seems to be more prevalent among young schoolchildren in Singapore than in southern China. Prevalence of myopia in children aged 7-9 years reported from the Singapore-China study was 36.7% in Singapore.Our initial research suggests that the pupil responds more if these cells have been exposed to a lot of sunlight in the previous few days. That could serve as a proxy for how much dopamine the eye has been producing.
