Blue light affecting the eyes has become one of the most discussed topics in everyday eye health. Therefore, it is important to understand how it impacts us and how we can properly protect ourselves.
How does blue light affect the eyes?
Prolonged exposure to blue light can cause digital eye strain. Blue light is part of the visible light spectrum and is characterized by a short wavelength and high energy. It occurs naturally in sunlight; however, in recent years artificial exposure has increased significantly due to the extensive use of digital devices. Proper protection from blue light is essential, especially for those who spend long hours in front of screens.
Where does blue light come from?
Blue light is emitted from:
-
Computer and laptop screens
-
Mobile phones and tablets
-
LED televisions
-
LED and fluorescent lighting
-
Natural sunlight
As a result, prolonged screen use has significantly increased daily strain on our eyes.
What problems can it cause?
Prolonged exposure to blue light may contribute to:
👁️ Digital Eye Strain
-
Dry eyes
-
Burning or stinging sensation
-
Headaches
-
Blurred vision
-
Difficulty concentrating
🌙 Sleep disturbances
Blue light affects the production of melatonin, the hormone that regulates sleep. For this reason, screen use before bedtime may impact both sleep quality and duration.
🔎 Long-term impact
Although research is still ongoing, there are indications that chronic and intense exposure may affect the retina over time.
How do blue light filter lenses help?
Blue light filter lenses are designed to filter part of the high-energy radiation emitted by screens.
Their key benefits:
✔️ Reduce eye fatigue
✔️ Minimize glare and reflections
✔️ Improve visual comfort while working on a computer
✔️ Contribute to better sleep quality
✔️ Ideal for office professionals, students, and children
Modern blue light lenses do not significantly alter colors and can be incorporated into both prescription glasses and non-prescription protective glasses.
Don’t forget regular eye examinations
Prevention is the most important step for maintaining healthy vision. Even if you are not experiencing noticeable symptoms, a regular eye examination can detect early changes in your eyesight.
