Eyes are not only the window to your brain but also a medium to communicate with the former.
In short, we perceive the views present in our surroundings via eyes and our body expresses its mental and physical trauma through eyes.
No, we are not talking about tears, but mental stress, tiredness, and all those emotions which cannot be expressed in words.
What stress can cause to your eye
According to a recent research, a person’s eyes can offer a solution to deal with stress levels caused by work productivity.
The study showed that the pupil dilation — widening of the pupils of the eyes — could be used to indicate levels of stress of a person in a multitasking environment.
“Many people multitask but currently there is no measurement for someone’s mental well-being. However, we found that the size of a pupil could be the key to measuring someone’s mental state while they multitask,” said Jung Hyup Kim, Assistant Professor from the University of Missouri in the US.
To understand how everyone experiences stress differently, the researchers used a simulated oil and gas refinery plant control room where they watched, through the motion-capture and eye-tracking technology, as the participants reacted to unexpected changes, such as alarms.
During the scenario’s simple tasks, the participants’ eye searching behaviours were more predictable. Yet, as the tasks became more complex and unexpected changes occurred, their eye behaviour became more erratic, the findings revealed.
It is expected that now devises should be designed as per the comfort of human eyes.
This will not only help the works getting rid of excessive work stress, but also build a safer working environment.
“One day this finding could give employers and educators alike a tool to determine the maximum stress level a person can experience before they become fatigued, and their performance begins to negatively change,” the study said.
Further, the researchers plan to apply this finding to further research involving different age groups and certain biometric measures such as heartbeat, brain signals and muscle or nerve reactions.
List of diseases that can be picked up by a simple eye test
Although it is not easy to find about the disease with an eye test, this inflammatory disease can be picked easily by examination. It usually passes from one generation to another, involves both the joints and the entheses (the sites where the ligaments and tendons attach to the bones).
One of the most common diseases, diabetes can be caught at an early stage by just looking into the eyes of a patient.
3. Advanced hypertension
Also known as blood pressure in layman’s language, advanced hypertension can show up bleeding in new blood vessels and cause retinal detachment.
The pale colour of eyes is one of the first signs to understand that the person is suffering from jaundice.
Doctors usually check eyes in order to understand the approximate blood level and flow as the cluster of veins are present right blow our retina and can indicate the disease.
6. Gardner syndrome
This is one of the most complicated disorders, causing the growth of multiple polyps in the colon, extra teeth and bony tumours of the skull.
