I hope you all are well. As the topic suggests, this blog will discuss why you should use blue light blocking glasses.
Our modern world is dominated by screens. From smartphones and computers to tablets and televisions, we’re constantly exposed to blue light. While this light is essential for daytime alertness, excessive exposure can lead to a range of issues, including digital eye strain, sleep disturbances, and potential long-term eye problems. This is where blue light blocking glasses come into play.
Why ,This is big Question ??
Digital screen emits some portion of harmful blue light ,which effect our eyes. As per study of Paris Vision Institute,blue-violet light within 415-455nm wavelength is potentially harmful .They cause oxidative stress at retinal level. Study show blue light could cause mucular degeneration later in life( which may result in blurred or no vision in the center of the visual field). The accumulation of the age pigment lipofuscin can start as early as in childhood, speeding up the aging process in our eyes.
What is Blue Light?
Blue light is a type of high-energy visible light emitted by digital devices. While it helps us stay awake and focused during the day, it can disrupt our sleep patterns when exposed to it in the evening. This is because it suppresses the production of melatonin, a hormone that regulates sleep.
How Does Blue Light Affect Us?
There are many reason such as headaches, sore or tired eyes,and stiff necks -all are the symptoms of eyestrain due to digital ecosystem as being continuously connected to digital system.As nowadays we are spending majority of our waking hours in front of digital screens puts our eyes through lot of wear and tear. At the same time, HEV light from our computers, phones and tablets doesn’t just cause our eyes to work harder, it could also put them at risk of aging faster.
The Impact of Blue Light
- Digital Eye Strain: Prolonged exposure to blue light can lead to digital eye strain, characterized by symptoms like dry eyes, headaches, blurred vision, and neck pain.
- Sleep Disruptions: Blue light exposure before bed can interfere with your circadian rhythm, making it difficult to fall asleep and leading to poor sleep quality.
- Potential Long-Term Effects: Some studies suggest a link between excessive blue light exposure and macular degeneration, a serious eye condition.
Benefits of Blue Light Blocking Glasses
- Reduced Eye Strain: By filtering out harmful blue light, these glasses can significantly alleviate digital eye strain symptoms.
- Improved Sleep: Wearing blue light blocking glasses a few hours before bedtime can help regulate your sleep cycle and promote better sleep quality.
- Potential Protection: While more research is needed, some experts believe that blocking blue light may help protect against long-term eye problems.
