Blue Light Vision Protection
No matter how old you are, limiting your exposure to blue light will help ensure that you’ll get to enjoy healthy vision for many more years to come. Your doctors at Aucello EyeCare Center can help you choose the right protective eyewear for your unique needs and figure out the best way to keep your eyes comfortable and healthy throughout the day.
What is Blue Light?
Blue light refers to light rays with wavelengths between 380 and 500 nanometers. It comprises the shortest, highest-energy waves in the visible light spectrum.
Where Does It Come From?
The sun is the biggest blue light source to which people are exposed, which means blue light can be found nearly everywhere. Other common sources include fluorescent and LED lighting and digital screens such as smartphones, tablets, computers, and televisions.
With 60 percent of people spending more than six hours a day in front of a digital device, the average person’s exposure to blue light is at an all-time high.
What are Its Effects?
As is the case with UV light, blue light has both good and bad effects on people.
Blue light is beneficial in that it helps you regulate your natural sleep and wake cycles, known as the circadian rhythm. It also helps elevate your mood, boost your alertness, and improve your memory and cognitive function during daytime.
While some blue light is beneficial in daytime, chronic exposure to it at night can disrupt your circadian rhythm and suppress the production of the sleep-regulating hormone, melatonin. Long-term nighttime exposure has also been linked to obesity, heart disease, depression, and certain types of cancer.
Regardless of the time of day, blue light can have damaging effects on the eyes. Just two consecutive hours of exposure can result in digital eyestrain and a noticeable reduction in visual clarity, sharpness, and contrast. Prolonged exposure can also contribute to permanent retinal damage and age-related macular degeneration.
How Can I Protect My Eyes From Blue Light?
Protective eyewear is one of the easiest and most effective ways to protect your eyes from blue light overexposure. They are recommended for indoor use in low-light and nighttime conditions and for general outdoor use.
The lenses used in protective eyewear have blue light filters, special coatings that reflect and cut high-energy blue light penetration. Tinted or polarized lenses also offer protection against blue light.
