The Science of Blue Light and Eye Health: What London, Ontario Residents Should Know

In today’s digital world, most of us in London, Ontario spend hours on phones, laptops, and TVs. While screens make life convenient, they also expose our eyes to something called blue light. This high-energy visible light penetrates deeper into the eye than other types of light, and over time it can lead to eye strain, headaches, and sleep disturbances.

Why Blue Light Matters

• Digital Eye Strain: Symptoms include blurred vision, burning eyes, and difficulty focusing.

• Sleep Cycles: Blue light suppresses melatonin production, making it harder to fall asleep.

• Long-Term Health: Research suggests extended blue light exposure may contribute to retinal damage.

Daily Habits to Help

• Follow the 20-20-20 rule: Every 20 minutes, look 20 feet away for 20 seconds.
