Do your eyes water — or feel uncomfortably dry — after a day in front of your computer? Does your vision get blurry after a day spent together with your needlework? Or possibly your eyes feel sore or drained after a protracted drive or after spending a couple of hours scrolling in your phone. Fortunately, regular breaks and a few easy adjustments may help keep your eyes comfortable as you go about your day.
What is eye strain and what causes it?
“Eye strain” isn't an official medical term or diagnosis. Rather, it is commonly used colloquially to explain eye discomfort, sometimes at the side of short-term vision difficulties.
Concentrating on a single task for long periods of time without interruption may cause symptoms that could be brought on by eye strain. For example, specializing in a detailed task for a very long time (akin to reading small print or doing detailed needlework) could make it difficult to chill out your attention whenever you look up and take a look at to concentrate on something distant. Eye strain also can occur from attempting to see in dim light or in other situations that force your eyes to work harder.
When eye strain occurs as a result of long sessions in front of electronic screens, it is usually often called digital eye strain or computer vision syndrome. The discomfort is commonly a results of our natural tendency to not blink enough when a screen.
Common activities that may cause symptoms of eye strain when performed for long periods of time with out a break include:
- Spending time on a pc, tablet, cellular phone, or watching TV
- Driving
- Reading, especially from small print or font size
- Needlework or other crafts that require constant, close attention.
Other aspects that may cause eye strain include:
- dim light
- Glare or very vibrant light
- Air blows directly into the eyes, causing dryness.
- Dust or dirt on the digital screen
- Bad weather while driving
- Wearing glasses or contact lenses with the fallacious prescription.
Symptoms brought on by computer vision syndrome or in lower than ideal conditions may make your eyes uncomfortable but not impair your vision. American Academy of Ophthalmology (AAO). Taking breaks and using artificial tears often helps.
Common symptoms of eye strain
What does eye pain feel like? Common symptoms include:
- Either dry or watery eyes
- Blurred vision or difficulty concentrating
- Eyes which are drained, sore, itchy, or irritated.
- Difficulty keeping your eyes open
- Muscle spasms within the eyes or eyelids
- Headache behind eyes
- Eye pain from vibrant light
Eye strain also can cause problems with concentration, productivity, or reading accuracy (as a result of blurred vision). Back, neck, or shoulder pain may end up from poor posture while attempting to compensate for drained eyes.
Tips to scale back eye strain
The following suggestions may help reduce eye strain.
Take regular breaks.
- Follow the 20-20-20 rule for close tasks: Every 20 minutes, take a look at an object 20 feet away for 20 seconds.
- Take a break after two hours or 100 miles of continuous driving – or as needed.
Keep eye surfaces moist
- Remember to blink (we rarely blink when reading print or a digital screen).
- Use artificial tears when driving or a digital screen for long periods of time.
- Wear glasses as a substitute of contact lenses, or use comfort drops for computer use.
- When driving, keep the wind away out of your eyes.
- Use a humidifier in winter.
Get a transparent vision
- Keep digital screen surfaces and glasses clean.
- Reduce daytime glare with polarized sunglasses, especially when driving.
Creating an eye-friendly workspace
The AAO recommends the next suggestions for organizing your workplace to forestall dry eyes and eye strain:
- Hold the pc screen 20 to 26 inches out of your face, with the middle of the screen barely below eye level.
- Face computer screens away from glare from windows or overhead lighting.
- Use a matte screen filter to scale back the glare brought on by a vibrant screen.
- Adjust the screen brightness and room lighting to concerning the same level.
- Increase on-screen contrast.
- Consider prescription computer glasses designed to focus at a distance of 25 inches.
- Sit in a snug chair that promotes good posture: feet flat on the ground with arms supported.
The AAO doesn't recommend blue light glasses, because there is no such thing as a strong evidence that blue light from digital devices causes eye strain.
