10 Screen Time Hacks To Save Your Eyes From Digital Strain
Your eyes are burning. Your head is throbbing. That familiar pain is creeping in after another marathon of online classes.
As an online educator, you spend countless hours in front of screens preparing lessons, teaching classes, and grading assignments. Your students face the same challenge. The digital classroom has transformed education, but the truth is- it is taking a toll on everyone's eyes. The only solution is to find ways to reduce eye strain.
