What Is Eye Strain?

Overall, chronic eye strain happens when your eyes become fatigued and overworked. You’ll notice symptoms like dull aches, dryness, and tiredness. Many people also have difficulty with their vision becoming blurred or even doubled. Others have frequent headaches before it becomes a chronic illness. The main cause of eye strain is looking at the screens of digital devices such as phones, tablets, and computers. Tom Chang MD´s advice is that the glare and blue light is hard on your eyes. You may also notice the same symptoms when you are driving or doing other activities that require intense focus. 


How Can I Treat It?

Giving your eyes time to rest helps to alleviate any discomfort, but there are other things that you can try that will help. Look away from focused activities once in a while. The popular 20-20-20 rule suggests looking at an object at least 20 feet away for 20 seconds every 20 minutes of screen time. He says that you may also lightly palm your eyes to counteract pressure. To keep on, Tom Chang MD suggests using good lighting to work and adjust your screen to a comfortable setting. Wear appropriate prescription eyewear to reduce strain. Blue light glasses are available to reduce the irritation. Spending hours gazing at screens can be unavoidable when it’s part of your job, but now you are equipped with the knowledge to protect your eyes and stop unnecessary discomfort.
