Dana AlKhiyami, a student at Northwestern University in Qatar, has been experiencing a lot of discomfort during lockdown due to the online learning environment and the sudden increase in focused screen time.
“I feel like my eyesight has gotten worse, with my left eye especially hurting more than usual and I have more migraines.” Said Alkhiyami.
A recent study on the Impact of the Covid-19 lockdown on ocular health, where 407 participants aged 19 and above took part in an online survey. The data showed that 65.68 percent of participants under the ages of 26 suffered from sleep pattern disturbances because of digital devices, and 66.9 percent of the students who took part had difficulties with sleeping on time.
The researchers measured 16 symptoms, three of which Alkhiyami is experiencing, and the number of times it occurs. They are all due to the decreased and incomplete blink rate, which negatively affects how the tear film is distributed hence stopping the meibomian glands from coating the eye with the oil it discrete to stop the tears from evaporating, so instead the tears would evaporate causing the eyes to dry out. Therefore, fully blinking is one of the most important preventative methods to limit the impact of digital eye strain.
There are also other minor environmental factors to look out for which contribute to drying the eyes, which are improper lighting, glare, and decreased humidity in airconditioned rooms.
Sherine Krause, chief executive at Fight for Sight, a charity organization that funds research into the prevention and treatment of eye disease and blindness, said in an article posted on their website,” We would urge employers to take their responsibilities towards staff seriously during this period of extended home working and to encourage employees to take regular breaks from screens.”
