Organized labour time today entails doing something that involves a screen, whether it is at work, on a mobile phone or watching television. Here is more time spent in front of screens and a growing worry about the effects that blue light will have on our eyes. This is where blue light glasses come into the picture. But do you really need them? Let’s explore.
What is Blue Light?
Blue light is a high energy visible light or HEV light occurring in calciferol, digital screen, LED light and even sunlight. While natural exposure to blue light during the day helps regulate our sleep-wake cycle, excessive exposure, especially from artificial sources, can lead to:
Digital Eye Strain: Some of the related signs include dry skin, inflammation, dizziness, hazy vision, and blurred vision especially when using screens for quite sometime.
Disrupted Sleep Patterns: Digital blue light disrupts the cycle of melatonin production which helps in controlling the sleep-wake cycle.
Potential Long-Term Eye Damage: It is also postulated that, when exposed to excessive blue light, retinal injury could be caused or aggravated in the long run.
What Are Blue Light Glasses?
Blue light glasses are characteristics of eyewear designed to reduce or eliminate exposure to blue light. There are initiatives to minimize its negative impact, something that makes staying on screen easier and less stressful on the eyes.
Who Needs Blue Light Glasses?
While not everyone requires them, you might benefit from blue light glasses if you:
Spend Long Hours on Screens: For those who spend at least 4-6 hours on a screen doing their job or their way of life, then blue light blocking glasses can lessen digital eye strain.
Experience Frequent Headaches or Eye Discomfort: These symptoms can be relieved by blue light glasses.
Struggle with Sleep Issues: If you are using screens late at night, blue light glasses will be useful by reducing the amount of light that interferes with melatonin.
Do They Work?
There is still current research going on in relation to the efficacy of blue light glasses. Some professionals insist that minimizing the time spent in front of blue light emitting devices will benefit the eyes and enhance night sleep; others say that using the features like night mode, taking regular breaks will do the same.
Advantageous of Using Blue Light Glasses
Reduced Digital Eye Strain: No more squinting and individuals will not get tired through their eyes; there will be improved dryness and therefore discomfort will be reduced.
Improved Sleep: Improved control over melatonin in instances when screens are used during the night.
Enhanced Focus: With less eye fatigue possible increases in productivity.
Stylish Options: Most companies today have stylish frames, and so it becomes a fashionable product.
Are There Alternatives?
If you’re unsure about investing in blue light glasses, try these alternatives:
20-20-20 Rule: Take a 20-20-20 rule, at least every 20 minutes, try to turn your eyes toward an object that is 20 feet away for a total of 20 seconds.
Adjust Screen Settings: There are settings on devices that you can turn on at night called “night mode” or “blue light filter”.
Use Screen Shields: These are films whose function is to block glare and blue light.
Limit Screen Time: Especially during the last one hour before sleepy time.
Final Verdict: Should You Be Wearing Blue Light Blocking Glasses?
Blue light glasses do not have to be prescribed as the typical glasses that are used to help people with their sight ails. However, if you have often complained of pain while using screens or after, these could work for you. Television is more recommended for those who frequently spend a lot of time viewing their screens or people who have eye problems related to digital screens or sleepless nights.
A Balanced Approach
In any case, it is crucial to remember that having good screen habits is crucial, even if you decide to purchase blue light glasses. Take breaks, make sure to dim the light and keep a safe distance from screens. Persistent symptom may be indicative of other conditions which requires the attention of an optometrist.
While it is unclear whether purchasing blue light glasses is necessary for everyone, they could certainly improve the user comfort and the screen.
