WHAT IS EYE STRAIN?
Eye strain is eye fatigue that mostly occurs due to overexertion. After long periods of reading, working on digital screens, or driving far distances without taking a break, you may experience eye strain symptoms such as:
- Eye pain
- Burning eyes
- Severely dry, or even watery eyes
- Light sensitivity
- Neck, back and shoulder aches (postural pain)
- Eye strain headaches
- Blurry vision
- Double vision
- Eye twitching
- Red and itchy eyes
THE CAUSES OF EYE STRAIN
Human's visual behavior has changed dramatically over the past 10 years with the increased dependency on information being delivered via digital screens such as smartphones, tablets, computer screens and television screens, of which, it emits a high amount of blue lights.
Blue light found at the very beginning of the visible light spectrum contains intense amounts of energy ranging from 400 nm to 495 nm. While measurements of blue lights emitted from individual devices are normally below dangerous levels, constant exposure to such intense energy actually forces your eye muscles to work overtime, and that causes eye fatigue.
According to the American Optometric Association, adults experience visual strain as a direct result of prolonged digital device use. In fact, it’s the most common cause. This vision problem is called digital eye strain, or computer vision syndrome.
According to The Vision Council, an independent group of eye doctors composed of optometrists and ophthalmologists, the average American spends more than 7 hours in front of a screen every day. While the human body needs a certain amount of blue light to control the sleep and wake cycle, overexposure can be unhealthy and cause eye strain.
OTHER CAUSES OF EYE STRAIN
