Everyone would agree how technology has become a vital part of our daily lives. Today, nearly five billion people use the internet. A considerable fraction of this uses digital devices for an average of six hours a day at the minimum. Spending that much time looking at a screen can lead to digital eyestrain. A few studies suggest that the discomfort could be due to the blue light emitted by these gadgets. Fortunately, there are now blue-light-blocking glasses available. Are you wondering whether they really help with digital eyestrain?
Here, we will share some insights into this technology:
Not all colors of light have similar effects. For example, blue wavelengths are known to be beneficial during the day as they boost attention and keep us alert. But it appears to be the most disruptive at night. The rise of electronic gadgets and energy-efficient lighting tends to increase our blue light exposure. This is especially true after sundown.
According to Harvard Medical School, exposure to light can suppress the production of melatonin in your body. It’s the hormone that influences your sleep-wake cycle. Light at night is one of the reasons why some people don’t get enough sleep. Researchers have also linked sleep deprivation to an increased risk of developing certain medical conditions. These include depression, diabetes, and cardiovascular diseases. Even dim light can affect your biological clock as well as melatonin secretion. Any kind of light can have this effect. But exposure to blue light at night seems to have a more powerful impact in throwing off sleep patterns.
Furthermore, The American Academy of Ophthalmology established that prolonged use of digital devices could cause temporary discomfort. Staring at your computer or digital screen will not cause permanent damage to your eyes. But you may experience eyestrain as manifested by dry eyes, blurry vision, and headache, among others. The primary cause is said to be the lack of blinking when you’re viewing your screen. But a few studies also linked overexposure to blue light as a potential contributory factor.
There’s still limited research that shows the efficacy of using blue lenses to ease the symptoms associated with digital eyestrain. But some agree that these special glasses help by filtering out blue light emitted from digital screens. They are a safe and drug-free solution to control and manage your light exposure during the day. The blue light filtering technology will help shield your eyes from the blue wavelength and even the ultraviolet rays from your digital device. The coatings on your lenses may also be treated to prevent glare, which can further lessen eyestrain.
Too much exposure to blue light can zap your energy and impact how you feel and function. Do you need help with choosing the best blue light filtering lenses for you? At NorthWest Ohio Vision Center, we can recommend the appropriate lens color and functionality that fit your needs and lifestyle.
