Do Photochromic Lenses Block Blue Light Emission?


 Lenses Block Blue Light Emission

Photochromic lenses are glasses that can get darker in the sunlight and protect your eyes from harmful UV rays. People usually buy them to make it easier to go from being indoors to outdoors, as they can adjust to changing light conditions.

They also eliminate the need for prescription sunglasses. Apart from this, photochromic lenses can also block blue light from the sun and electronic devices, which can be helpful for people who spend a lot of time looking at screens.

So, while blue light protection is a feature of these lenses, it is not the main reason people buy them.

Photochromic Lenses Block Blue Light Completely from Screens

Definitely! Photochromic lenses can be an excellent choice for using the computer because they can block blue light, despite being made initially for a different reason. Blue light can be bad for your eyes, especially if you spend a lot of time in front of screens or out in the sun, as any light can negatively affect your eye health.

But photochromic lenses can shield you from the strongest energy level on the light spectrum, which also means that they can protect you from blue light and make a good option for using the computer.

Impact of Blue Light on Vision

Blue light, which comes from screens on devices like phones and computers, can cause harm to your eyes and even disrupt your sleep cycle. Although a little blue light can be helpful for sleep, we usually spend too much time in front of screens. Here is a list of some possible side effects of blue light exposure:

  • Cataracts: Blue light can cause cells that can lead to this eye condition.
  • Insomnia:Blue light can make it challenging for you to sleep and may make you stay awake for longer.
  • Macular degeneration: Retinal damage caused by blue light can be linked to macular degeneration.
  • Restless sleep: Even if you manage to fall asleep quickly, blue light can reduce the restful benefits of sleep.
  • Digital eye strain: Continuous exposure to blue light can cause strain on your eye muscles.
  • Blurry vision: Your vision can become blurry when your eye muscles weaken from digital eye strain.
  • Dry eyes: Not blinking enough due to heavy blue light exposure can cause your eyesto dry out.
  • Headaches:Trying to see when your eyes are tired, and your vision is blurry can cause headaches.

Photochromic lenses are helpful not only for their convenience but also for the protection they provide against harmful overexposure to blue light.
