This Is What You Need To Know About Asthenopia!
In today’s gadget driven environment, working long hours can take a toll on the eyes. More often than not, people’s eyes are affected due to this strain, and they rarely notice it until the symptoms are prominent
Asthenopia or eye strain is a common eye condition in which eyes are fatigued resulting from close work for a long duration. Sadly, this is an extremely common disorder and most people do not even realise that they have fallen prey to the damage that it causes.
Sadly, there is no specific threshold after which the symptoms start to show up. Therefore, the only way that people can avoid eye strain from damaging their vision is keeping an eye on the symptoms. Eyes are the second most complex organ in the human body after the brain.
The Seeing Mechanism
Before we delve deeper into the subject of how asthenopia affects your vision, let’s get an insight into how the eyes are able to see. For the eyes to see anything clearly, light coming from the object of interest must enter the eyes and converge on the retina. The neuronal layer of the eye connected to the brain, will now get into action to perceive the details of the image generated, accordingly helping the individual see.
Now if the object is located at a certain distance, the eyes do not have to strain themselves as the light emitted converges comfortably on the retina. But if the object is located at a further distance, the eyes need to strain the ocular muscles in order to ensure that the rays converge at the required point on the retina. This type of strain for extensive durations of time can be fatal for the eyes. On such occasions, the strain is what makes the eye asthenopic.
