Eye strain, also known as computer vision syndrome or digital eye strain, is a common condition that occurs as a result of prolonged use of digital devices such as computers, smartphones, and tablets. It is characterized by symptoms such as eye fatigue, headache, blurred vision, and dry eyes. The blue light emitted by digital screens and the glare from the screens can cause eye strain, as well as improper viewing distances and incorrect posture while using the devices.
To reduce eye strain, it is important to take frequent breaks, adjust the brightness and contrast of the screen, and maintain a comfortable viewing distance. The 20-20-20 rule is a useful way to reduce eye strain - every 20 minutes, look away from the screen and focus on an object 20 feet away for 20 seconds. Additionally, adjusting the screen position to reduce glare and using anti-glare filters can also help. Blink frequently to keep the eyes lubricated, and make sure to practice good posture while using digital devices. Using artificial tears can help soothe dry eyes, and it's also recommended to limit the amount of time spent using digital devices in low light conditions.
