Asthenopia — or eyestrain — is a common condition characterized by blurred vision, pain around the eyes, headaches, and double vision. It’s caused by visually demanding tasks like reading, knitting, or working on a digital screen for extended periods. Although the condition does not cause permanent damage, it leaves you feeling fatigued and can exacerbate other conditions. Therefore, preventing eyestrain is crucial to comprehensive vision care. Here, the knowledgeable team at Honolulu’s Kato & Shoji Optometrists shares everything you should know about asthenopia. 

Common Causes of Eyestrain

Other causes include driving long distances, spending time in bright sunlight, straining to see in dim lighting, and being exposed to dry air. Although the symptoms of eyestrain will ease when you step away from these irritants and rest your eyes, they can worsen underlying vision care problems like dry eye. 

Preventing Eyestrain

To reduce strain, increase the text size and enhance the contrast on your devices. Placing an anti-glare screen protector on your smartphone or tablet can also help.

To prevent tired and sore eyes, take frequent breaks when performing activities that demand intense focus. You can also improve the air quality in your home or office by using a humidifier and adjusting the thermostat to eliminate dry air.
