by Cheryl E Preston 2 months ago in Science

Investing in a pair of these lenses might help you sleep better as well as reduce your risk for certain health issues.

If pixal peeping is causing you problems then you might want to invest in a pair of blue light glasses. If you are using a computer or cell phone on a regular basis you could be experiencing eye strain, eye fatigue, headaches, and or be unable to sleep. Blue-light stimulates the brain and Blue-light-filtering lenses may be an assist. These glasses filter more blue light than our standard high index or polycarbonate options.

This makes blue light filtering glasses ideal especially for online writers and those who are making a living through the Internet by other methods. If you wear prescription glasses ask your optometrist what you need to do to obtain a pair. If you use readers you can purchase blue light lenses in the appropriate strength. You can find different options for them online and even bargains to buy 2. 3, or 5 pair at a discount. You can also purchase them at Target or Walmart.

Blue light filtering lenses may also be beneficial to migraine sufferers and wee recommended to someone I know who suffers from severe migraines. I’m wearing a pair of blue light readers now and everything I look at seems clearer and brighter. I can also see further in them than traditional readers. I find these glasses improve the lighting on my television also. Although it is environmentally friendly and is used to stimulate some brain damaged patients blue light has possible side effects. It can affect your ability to get a good night's sleep and potentially cause disease.

The sun was once the major source of lighting, and in the evening's people were in darkness. Before electric lights. everyone blew out their candles and slept by the light of the moon and stars if they wee visable. Now, in much of the world, evenings are illuminated. Sometimes street lights shine through windows and prevent rooms from being in total darkness. Television networks used to go off around midnight but now programming can be viewed 24/7. Some people even go to bed leaving their TV's on.

Medical science now suggests that we may be paying a price for basking in all of that unnatural light. During the night, light throws the body's biological clock off. When this circadian rhythmic is off kilter it causes othe issues. In addition to disturbing our sleep research shows that blue light may also contribute to causing obesity. diabetes, cancer, and heart disease.

Researchers from Harvard did a study where they put 10 people on a schedule that shifted the timing of their circadian rhythms gradually. The results indicated that the blood sugar levels of the participants increased, which caused them to become pre-diabetic. They also found that levels of leptin a hormone that leaves you feeling full after eating decreased. If you don't feel full you will condume more food and eventually pack on thye pounds.

Exposure to light also suppresses the secretion of melatonin, which is the hormone that affects circadian rhythms and helps you sleep. Studies reveal that even dim lighting interferes with melatonin secretion. Late night use of laptops, tablets and cell phones can cause you to be unable to wind down and get a good night's sleep. Harvard researcher Stephen Lockley says light during the night is part of the reason so many people are sleep deprived. He added that decreased sleep can increase the risk for depression, as well as diabetes and cardiovascular problems.
