It is a well-known fact that blue light glasses can be extremely helpful to our eyesight. With so many people spending more time working on computers, it is more likely than ever before that we will come into contact with the blue light emitted by these devices. It is possible that prolonged exposure to excessive blue light may lead to serious problems for your eyes. This is why blue light glasses have been designed to combat this problem.
What Are Blue Light Glasses?
What exactly are blue light glasses? Blue light blocking glasses have specially designed lenses that are designed to either filter or block out all the blue light given off by computer monitors. The special lenses help to reduce possible damage to the retina and prevent prolonged exposure to harmful blue light from computer screens. These special lenses do not use chemicals, but a rather organic compound called Silicon(III) that helps to create a more powerful filter. The filtering is actually located inside the lens and is created to stop harmful blue light from passing through onto the retina.
How Do They Work?
How can blue light glasses help to treat eyestrain? As already mentioned, the use of computer screens can put tremendous stress on the eye. One of the symptoms of eyestrain is blurriness and eye fatigue, which makes seeing difficult. Blurriness can also make vision difficult as the eye is forced to work extra hard to focus on the screen. They can help your eye to relax when you are in front of a screen and they can also help regulate your natural melatonin cycle, which is important for sleep.
Prescription Lenses & Blue Light Filters
If you need prescription glasses, you may benefit from blue light glasses. Most blue light glasses manufacturers can build you a lense with your prescription in it, giving you the best of both worlds. A good optometrist will be able to help you find the right combination of prescription glasses and blue light glasses that will help you see better while at your computer.
What About Sleep?
The use of blue light glasses can even help prevent eye strain and fatigue during the day. But studies have shown that people who wear blue light glasses often get a better nights sleep than those who don’t. A good night’s sleep is absolutely necessary for good health, which in turn means that the body will be able to rest properly and fight off disease much better. Wearing blue light glasses increase the amount of sleep that you get each night, resulting in a healthier lifestyle overall. This is due to the fact that blue light blocks the body’s natural melatonin production, which is the hormone responsible for your sleep cycle.
People who are suffering from diseases such as cataracts and macular degeneration can benefit from blue light lenses because these individuals may be prone to dry eye syndrome. Dry eye syndrome occurs when the muscles around the eyes become damaged, which causes the eyes to become less moist and thus more susceptible to drying out. This can then cause the eyes to be more easily irritated and it can even be painful. Redness and swelling around the eyes is also a sign of dry eye syndrome. Individuals who wear blue light glasses on a daily basis can prevent this condition by wearing their lenses at bedtime.
