How Computer Glasses Help You Reduce Eyestrain

 

 

Computer glasses have recently gained quite a popularity due to the range of benefits they offer. Computer glasses can block a significant percentage of the blue light that emits from your mobile phones and computer screens. Their blue light blocking capacity ranges from 60% to 90% depending on the type, material, and cost of the glass. However, computer glasses are not some exclusive made-to-order glasses that are beyond the reach of a majority of customers.

To understand how computer glasses help us, let’s first understand what Blue Light is and how it impacts our eye health?

 

What is Blue Light?

Blue light is the closest to the invisible UV light in the visible light spectrum. This is high-energy visible light that has a shorter wavelength and it impacts our eyes more severely than any other color in the spectrum of light. It affects our retina in a bad way and in fact, excessive exposure to blue light can also disturb our body clock.

 

The Dangers of Blue Light

Since blue light and UV rays are similar in nature, they pose a serious risk of different types of eye diseases. Apart from the severe diseases themselves, side-effects of blue light start with dry, irritated eyes, and develop into blurred vision.

Blue light exposure for long hours also results in phototoxicity which is a condition of damaged retinas. The severity of the damage depends on the amount of exposure and duration of exposure over a long period of time.

 

How Computer Glasses/Blue Light Filter Glasses Reduce Eyestrain

The main reason for computer glasses being effective in reducing the eyestrain is their special tinted coating that blocks the majority of the blue light emitting from your computer screen. Computer glasses also slightly adjust the focus to emulate a scenario in which your brain is deceived into thinking that it is focusing on something far away.  

While it is easy to buy computer glasses online, you need to be aware of certain factors while choosing the right computer glasses. Let’s have a look!

  • The computer glasses must have an anti-glare and filtering coating to ensure that the blue light defense that you are seeking works in sync with other aspects of increasing your visual prowess and improving your overall experience.
  • Also, ensure that the computer glasses you are looking to buy also have UV protection including UAV and UAB protection. This is simply an all-in-one solution that will help you out in both indoor and outdoor situations.
  • Lastly, not all blue light blocking glasses or computer glasses are of top quality and you need to be mindful of such factors. Whether you are buying glasses online or from a local store, always consult with your ophthalmologist and see which brand they recommend.

 

Apart from the computer glasses themselves, you can do other things to reduce your eyestrain such as taking a short break every 1.5-2hrs while working and washing your eyes with cold water. This will keep your eyes hydrated, reduce stress, and also minimize the damage to your eyes.
