Blue Light Blocking Technology in Modern Glasses
Blue light blocking glasses for kids: The truth is that blue light is not all bad. It doesn’t always have to be blocked. It can aid memory, increase attention, and improve your mood! Still, the over exposure of eyes to blue light from digital screens of smartphones, tablets and computers may quickly lead to eye strain.
Definition of blue light
Sunlight is made up of seven different colored lights. When combined, it becomes the white light that we see. Each light has a different energy and wavelength. The rays in the red end have longer wavelengths and less energy. At the other extreme, blue rays have shorter wavelengths and more energy. White light can have a solid blue component and expose the eye to a longer wavelength from the blue end of the spectrum.
Eyes’ exposure to blue light
Blue light is mainly delivered to the planet in the form of sunlight. In addition, there are many other sources:
- Fluorescent light
- Compact fluorescent lamps
- LED lighting
- Flat-screen LED TV
- Computer, smartphone, and tablet screens
The blue light exposure you get from your monitors is low compared to the amount of sun exposure. And yet, the long-term effects of screen exposure are of concern due to the proximity of the screens and the time it takes to look at them. A recent study on vision concluded that the kids’ eyes absorb relatively more blue light than adults by digital screens’ exposure. SmartBuyGlasses with their wide range of glasses can prevent you from getting digital eye strain if you are exposed to blue light on a daily basis when using a smartphone, laptop, or tablet. In their online store, blue light glasses are more accessible and affordable than ever before. They provide customers with a wide range of eyewear services to fulfil all of their requirements.
Benefits of blue light
Blue light is often considered essential for good health as it increases alertness, supports memory and cognitive function, and improves mood.
Circadian rhythm and the body’s natural sleep-wake cycle gets regulated by blue light. However, too much blue light exposure late at night can disrupt the sleep-wake cycle and cause sleep disturbances and fatigue during the day.
Inadequate sun exposure in children can affect the growth and development of their eyes and vision. Some studies suggest that lack of blue light exposure may contribute to the increase in myopia.
Blue light’s effect on the eyes
Blue light reaches to retina after passing through the lens and the cornea inside a human eye. This light can adversely affect vision. A couple of studies show that overexposure to blue light may lead to:
Digital eye strain: Blue light from computer screens and digital devices can reduce contrast and cause digital eyestrain. Fatigue, dry eyes, insufficient lighting, or sitting in front of the computer can all strain your eyes. Symptoms of eyestrain include sore or itchy eyes and trouble focusing.
Damage to the retina: Ophthalmologists suggest that continuous exposure to blue light can damage the cells of the retina. This can lead to different vision problems, including macular degeneration. Blue light blocking glasses for kids
Blue light protection for your eyes:
If constant exposure to light bulbs from smartphones, tablets, and computer monitors is a problem, here are some ways to reduce blue light exposure:
Screen time: Try reducing screen time and take frequent breaks to rest your eyes.
Screen Filters: These are available for smartphones, tablets, and computer screens. They help to reduce the amount of blue light that can reach the retina of our eyes.
Computer Glasses: Computer glasses with yellow lenses that block blue light can help illuminate digital computer glass by increasing contrast.
Anti-reflective lenses: Anti-reflective lenses help increase contrast, decrease glare, and block the blue light released from the sun and digital devices.
Intraocular lens (IOL): The diffuse lens is replaced by an intraocular lens (IOL) after a cataract. The lens protects human eyes from the dangers of UV and blue light. There are types of intraocular lenses that can protect the eye and retina from blue light. Blue light blocking glasses for kids
