Most people that suffer from short-sightedness or long-sightedness have to wear spectacles or lens at all times for clear vision. If you are one of them, you know how important the glasses are. Most people can�t even move an inch before putting on their glasses.

The problem gets worse if you are a user of various digital screens. The blue light coming out of the digital screens can be really harmful to your eyes, deteriorating your eyesight and make you completely dependent on your glasses. Normal spectacles might not be enough to ward off these rays. However, blue light glasses are supposed to do the trick.

How?

Let�s find out the answer.

Blue Light Glasses

Even if you can see clearly without glasses, using digital screens all day long can leave your eyes tired and dry. It also messes with your sleeping schedule, affecting the circadian rhythm that tells you to sleep or wake up when it�s time.

Blue light glasses claim to filter out the blue light coming from the screen and save your retinas from additional strain. They have special lenses, specifically made to counter the effect of blue light. Prolonged exposure to blue light can damage your eye. However, blue light blockage glasses claim to be effective in filtering out this harmful light. These glasses have become the latest wellness trend.

Do Blue Light Blocking Glasses Work?

The the discomfort you feel after a long day of using a digital screen mostly falls under �Computer Vision Syndrome�, widely known as CVS. When we stare at the digital screen or far too long, our cornea becomes dry because we are not blinking as much. This will ultimately read to discomfort or irritation.

So instead of spending money on a new technology with no practical data that can vouch for its healing property, exercise the 20-20-20 rule, as suggested by Ophthalmologist Rishi Singh. Rest your after every 20 minutes to look 20 feet for 20 seconds. This will regulate eye movement and cause your eyes to relax. You can also use eye drops to ward off the dryness in your eyes.

An institute called the American Academy of Ophthalmology has said on record that due to lack of scientific evidence, we do not recommend blue light-blocking glasses.

There is not enough evidence that supports the healing claims of blue light-blocking glasses. As published on Cleveland Clinic�s official website, most eye issues caused by digital screens are not because of the emission of blue light. However, excessive exposure to this light can definitely mess up your sleeping patterns. Therefore, you should switch off all the digital screens at least one hour before sleeping.
