BLUE LIGHT – WHAT IT DOES TO YOU AND HOW TO PROTECT YOUR EYES?
Blue light has dual characteristics – a healthy side but it has also a dark side.
Healthy Blue light, in its natural form from the sun:
- Allows us to differentiate between day and night
- Manages our circadian rhythm; both when we are awake and during our sleep
- Improves our cognitive performance and keeps us alert.
So, how Blue light tumbles into the dark side, affecting your eyes?
- Light emitting diodes (LED) emits BLUE LIGHT and is found in virtually all light emitting appliances such as fluorescent lamps, computer screens, laptops, mobile phone screens and tablets.
- Wavelengths within the blue-violet portion ( 415 to 455 nanometers) of the light spectrum are considered to be most harmful to the retinal cells. Most of the devices that we use emit a high level of blue light, wavelength that starts around 400nm.
- It turns you into a night owl. An over exposure of blue light from digital devices during the evening will block the release of melatonin, a hormone released during the night to reduce alertness to help induce sleep. So after a night of watching TV or being on Facebook or WhatsApp, you may feel like a zombie.
- A more permanent damage of artificial blue light is a premature degeneration of retinal cells, leading to long term vision problems. Retinal cells process light and colours and once damaged, they cannot be replaced naturally or artificially.
- Overexposure to digital devices emitting blue light can also contribute to digital eye strain.
WE HAVE THE SOLUTION!
Nowadays, whether it’s for work or personal use, most of our time is spent in front of a screen. Hence, Blue Light Filter Lenses or Filtering Glasses are recommended.
Proper filtering of those blue light will boost up the naked eye physiology leading to visual efficiency.
Combat Digital Eye Strain with the right Lens Technology:
- These lenses cut glare, block out blue light from penetrating your over-strained eyes
- These lenses prevent vision fatigue when you stare at digital screens
We will advise you on which type of computer eye-wear is right for you, your lens options, lens treatments and filters.
Here are few tips that will help you take better care of your eyes:
Use technology responsibly, be aware of how much time you should spend in front of a digital screen
Ensure that your lighting is correct and appropriate
These are things you can discuss with us. We want to help you take better care of your eyes with solutions to relieve painful eye strain.
