Do you work in an office perhaps, and spend a lot of time in front of a computer screen? If you work in front of a computer for any length of time, it is common for you to experience symptoms such as red eyes, blurry vision, and eye strain.
You also may find it hard to focus in on details on your computer screen. This is because your eyes may have difficulty when you look away from your screen and then look back at it again.
Thankfully, there are reading glasses or computer glasses that can help to remedy this common scenario. But before we talk about a solution, let's dive a little deeper into the main cause of eyestrain, which is blue light.
Defining Blue Light
What exactly is blue light anyway? To give you an idea, the highest amount of blue light exists in sunlight. A little bit of sunlight is good for you, but too much can hurt you, right? The same goes for blue light.
Each color within sunlight has its own energy and wavelength. Blue rays have the shortest wavelengths and the most energy. A light that looks the whitest, can have the largest amount of blue in it.
Sources of Blue Light
To begin, let's talk about all the devices that emit blue light. They include computer monitors, smartphones, and tablet screens. Of course, this means that your children are also likely being overexposed to blue light.
Flat-screen LED televisions emit blue light. So do fluorescent light bulbs.
Effects of an Excess of Blue Light
At night, too much exposure to blue light can cause your wake and sleep cycle to become disturbed, which in turn can lead to sleeplessness and tiredness throughout the day. Blue light delays the release of melatonin, which the body needs in order to fall asleep.
According to the Prevent Blindness Organization, exposure to an excess of blue light can lead to digital eyestrain. Symptoms include sore or irritated eyes, and trouble focusing. Over time, continued exposure could even lead to age-related macular degeneration.
Protecting Your Eyes Against Blue Light
Logically, the first thing that you can do is limit the amount of time that you spend in front of your computer screen, if possible. However, if your job involves being in front of a computer all day, that isn't going to be a possibility for you. Let's take a moment to talk about one of the hottest products on the market right now, blue-light blocking computer glasses.
Did you know that the average worker spends around 1,700 hours a year in front of a computer screen, just at work? Computer glasses are growing in popularity, for good reason!
Computer glasses that block blue light help to reduce eye strain. When you use blue-light blocking glasses, you may find that your eyes feel more comfortable and less fatigued.
There are also computer glasses that magnify what you are looking at, much akin to reading glasses. This means that they can be customized to your individual needs.
In today's digital age, avoiding an excess of blue light may be too much to ask for. Thankfully, with the help of customizable eyewear, we can limit how much blue light reaches our eyes. Making a smart decision to purchase computer glasses will ensure that you can work more comfortably and perhaps sleep easier at night.
