Online classes, no doubt, provide students to catch up on the classes lost due to the prolonged lockdown as a result of the COVID-19 pandemic. But, attending classes online without a break is said to be causing problems like dry eye syndrome, burning sensation of eyes, and ear problems. Doctors suggest the use of laptops and external speakers, instead of earphones, to avoid eye and ear problems. Prolonged use of earphones can result in noise-induced deafness. Also, there is a large section of the population that is unable to access technology and that’s a huge concern. Children belonging to migrant families might have moved far away from their schools.
