Our eyes are organs of remarkable feel that allow us to connect and see the world around you. The eyes are exposed daily to many stimulants and nevertheless managed to efficiently process all kinds of new information without even having to give too much importance.
Unfortunately, however, the time spent in front of screens, digital lifestyle and aging can slow down the efficiency of the eye and can put pressure on them. And one of the most damaging things for eyes is light blue. In other words, it is time to ask ourselves some questions about the real consequences of using constants.
Visible light is characterized by the length of the waves and how much power it produces. The wavelength is longer, so it produces less energy (safe) and the shorter wavelength of light, so it produces more energy (a potentially harmful). Red light, like the one from a radiator, is an example of the long wavelength light with little energy.
Blue light, as the screens used by the computer, cell phone, and television has the waves shorter and therefore the largest energy. Blue light is harmful to the eyes because, unlike other UV rays that are blocked by the pupils, corneas and virtually all the visible blue light passes through them and go directly to the retina that is sensitive to light and can lead to the development some degenerative diseases and the loss of vision.
Although we are exposed to a small amount and healthy blue light from the Sun during the day, excessive exposure occurs when we spend the too long night without screens that emit large amounts of blue light.
Long periods of time in front of screens digital tire your eyes and can lead to other symptoms, such as straining eye, dry eyes, headaches, fatigue, blurred vision, difficulty concentrating and sleeping problems.
A study conducted by researchers at the Harvard Medical School has found that exposure to light at night suppresses melatonin production blue twice more than
light green and disrupted circadian rhythms twice more.
There are, however, steps you can take to protect your sight from stress and light blue.
Here’s where you can start:
1. Use the computer and mobile phone sparingly.
How to spend time daily in front of the computer, on the phone or in front of the tv? Probably much more than you imagine.
A small study carried out by British psychologists has found that young adults spend an average of five hours a day on the phone. To these is added and the eight hours in front of your computer plus time spent the evening watching television. Gather a large amount of time spent in front of screens with blue light. It is important to take small breaks, raising his eyes from the screen for every 2-3 minutes 15-20 minutes.
Reflection on digital screens can damage your eyes, so it is recommended to use desk lamps to control the reflection that can come from nearby Windows.
There, too, and glasses that block blue light, which can filter the light that comes from digital equipment. This type of filters for blue light and can be installed on many types of smartphones!
2. Change your lifestyle.
There are a few changes in lifestyle that can lessen the stress to which they are subjected to. These include Sunglasses: the way you protect your skin with sunscreen cream, you need to protect your eyes with sunglasses. It is preferable to have amber lenses with 100% UVA and UVB protection.
3. Quit smoking.
Smoking produces cyanide within the body, which is harmful to the eyes. Maintaining the eyes moisten: it is important to blink several times during the day to keep the eyes moist. If you live in a dry climate area and you need an external source of moistening of the eyes, use homeopathic drops or a humidifier. Sport: sport is good for the whole body, but also for the eyes. We recommend at least 20 minutes of cardio exercise per day (walking, running, swimming etc).
4. Consume foods beneficial for eye health.
Intense-colored foods that contain antioxidants and carotenoids — protects the eyes of blue light and other stress factors. Three carotenoids zeaxanthin are important for eye, lutein, and astaxanthin.
Unlike other antioxidants and carotenoids, they can bypass the blood-retina barrier to reach the eye, providing protection for views. Zeaxanthin is present in green vegetables like spinach, kale, and broccoli. Lutein can be found in leafy vegetables, and fruits and vegetables Orange like carrots, peppers, tomatoes, and corn.
Lutein and zeaxanthin are present in high concentrations in the macula of the eye and can prevent blue light to reach the Interior of the eye, including the retina. These acetonides can reduce any negative effects of light on the eye, which causes macular degeneration. Astaxanthin is a red pigment of nature which proved to be a powerful antioxidant and a carotenoid.
It is found in the algae water flowing from Haematococcus Pluvialis species, used mostly in the form of nutritional supplements. Studies have shown that astaxanthin can help your eyes in many ways, including a reduction in stress, better visual accommodation (ability to adapt the pupil, which allows him to create the image), faster recovery after eye fatigue and decreased sensations of pain, dryness, fatigue and blurred vision.
Astaxanthin, along with the macular antioxidants lutein and zeaxanthin, strengthens the resistance of the eyes when they are exposed to digital screens for long periods of time and improve Visual performance after prolonged exposure to blue light.
Although it is almost impossible to avoid digital screens today, these measures can protect your eyes and make them help us to enjoy the beauty of the world around us.
