Blue light is an inevitable part of our digital lives. We are constantly exposed to it, whether through our laptops and phones or simply by being out in the sun. However, continuous exposure to it can damage our eyesight and even impact our sleep patterns. Alderwood Optical & Canyon Park Vision Clinic provides an overview to help you understand the extent of its effects on our eyes and overall well-being.
Blue light refers to the portion of the visible light spectrum with the shortest wavelengths produced by digital devices and the sun. It would appear more akin to a colorless beam to the naked eye. However, it impacts the body in quite tangible ways.
Sensitivity to blue light can manifest in several ways. Recognizing these signs ensures that you can take appropriate preventive measures. Symptoms of blue light sensitivity may include:
Frequent headaches. If you’re experiencing frequent headaches after prolonged exposure to screens, it might be a sign of blue light sensitivity.
Eye strain or fatigue. Spending a considerable amount of time in front of screens can cause your eyes to feel tired, strained, or uncomfortable.
Difficulty focusing. Excessive blue light exposure can interfere with your ability to focus, both visually and cognitively.
Dry or irritated eyes. Blue light can cause dryness or irritation in your eyes, leading to a constant need to blink or rub your eyes.
Blurred vision. If you notice a decrease in visual acuity after using digital devices, it may be due to blue light exposure.
Disrupted sleep patterns. If you’re having trouble falling asleep after using digital devices in the evening, it could be due to the blue light emitted from these devices.
These symptoms can vary from person to person. It is always best to consult an optometrist for a proper diagnosis and intervention.
Symptoms of blue light sensitivity can often be confused with other eye or health conditions. During an eye exam, your eye doctor will review your medical history, symptoms, lifestyle habits, and digital device usage. If blue light sensitivity is suspected, your eye doctor can discuss suitable treatment and prevention strategies.
You can protect your eyes from excessive blue light through simple lifestyle changes. Regular screen breaks and wearing protective eyewear can contribute to limiting its potential harm. The 20-20-20 rule also works. Every 20 minutes, look at something 20 feet away for 20 seconds.
