Observational study on effect of myopia associated with poor sleep and screen time

Abstract

Myopia or short-sightedness is the most common vision disorder among children and young adults in which defective vision and loss of vision occur.  Global cases of myopia are on the rise, with some research indicating a link between excessive screen use and on the onset of the condition. In myopia patient can see objects near to them clearly, but objects far away like road signs are blurry. The condition is caused by excessive elongation eye. As a result the rays of light entering the eye focus in front of the retina instead of directly on the retina, causing blurriness. In Ayurveda symptoms of   Timira can be considered as more similar to refractive error i.e. myopia. With screen based devices, e.g., tablets, smart phones, laptop, computers, televisions etc. these causes glare, extra eye strain, dry, irritate eye, loss of focus flexibility i.e. eyes stay focused close-up for long periods then it is difficult to adjust to distance vision. And increases the risk of myopia. The blue light from computer and device screens, when used in the evening, alters the brain’s sleep rhythm. The brain reads the screen light as daytime and shifts the body’s circadian rhythm which causes poor sleep time. The main object of this study is to know the incidence of myopia associated with poor sleep and screen time. The study was carried out as an observational study among 100 volunteers having poor sleep and more screen time.
