Computer Blue light and Eye’s

Blue light is not necessarily bad. Certain wavelengths of blue light can help boost mood as well as alertness, memory and even cognitive function. But, recently researchers are warning that overexposure due to the time we are on electronics that generate thee wavelengths can cause eye problems over time.

According to an article in the American Optometric Association journal “Early research shows that overexposure to blue light could contribute to eye strain and discomfort and may lead to serious conditions later life such as age-related macular degeneration which can cause blindness.” Other research has shown that overexposure to blue light can accelerate the aging of eyes and lead to dry eye and eye fatigue even when you view your electronic screen for only short periods of time.

To protect yourself if you have to be on the computer a lot you could supplement with lutein and zeaxanthin. Both are found naturally in the eye and are responsible for protecting the eye from light-induced damage. Studies have shown that increasesed consumption of these ingredients lowered risk of developing macular degeneration.

Additional research has shown that children are a greater risk as their crystalline lenses are more transparent and more susceptible to these short wavelengths associated with blue light and LED lighting found in many classrooms.Food that contain lutein are fruit, vegetables such as broccoli, grapes, kale , kiwi, spinach, zucchini many of which also contain zeaxanthin (also found in egg yolk, orange tangerines and turnip greens).

Cutting your blue light exposure is key but not always possible in our tech-centered culture. To change the light so it is not so blue after dark, search online for a download that alters your screen color to a more rose shade. This will also reduce the attack on melatonin of which the production is hampered by the blue light. This will help (especially your teenager who is on a screen until the last moment at night) reduce insomnia.
