What is Blue Light?
Blue light is a colour in the light spectrum that you can see (like the colors of the rainbow). The sun is the biggest source of blue light, and there are smaller sources like TVs, certain light bulbs, smartphones, tablets, and laptops.
Looking at too much blue light can make your vision blurry, and your eyes tired, and might even lead to eye problems like macular degeneration and cataracts.
How can blue light affect your eyes?
Eye discomfort and dryness: If you spend a lot of time looking at screens, it can strain your eyes and make them dry. This means your eyes might not have enough moisture, either because your tears evaporate quickly or because you forget to blink often. However, this issue is more about screen time in general, not just the blue light.
Macular Degeneration: Too much blue light can harm the cells at the back of your eye and cause vision problems as you get older. Most of this harmful blue light comes from the sun, and scientists are still studying how much smartphones and computers contribute. For Macular Degeneration Treatment in Mumbai, you can visit Dr. Vaidya Eye Hospital or book an online appointment with Dr. Harshit Vaidya.
After Cataract Surgery: If you have cataracts or are getting ready for cataract surgery, it’s a good idea to have a conversation with your eye surgeon about the kind of artificial lens they will use to replace your cloudy natural lens. This decision is important because it can affect your vision and how well you see after the surgery. Your surgeon will guide you in choosing the right lens for your specific requirements and lifestyle, ensuring you have the best post-surgery visual outcome.
Is it true that all blue light is harmful to us?
Light therapy has found a purpose in treating seasonal affective disorder, a kind of depression that often comes from not getting enough sunlight during certain times of the year.
Getting too much blue light at night can make it hard to sleep and leave you feeling tired during the day. However, during the daytime, it can actually assist in regulating your body’s natural wakefulness and sleep pattern, which is like your body’s built-in alarm clock. So, if you manage your exposure to blue light well, it can be beneficial for your body.
What’s the function of blue light filters?
More and more people are using glasses and coatings that claim to block blue light, but there isn’t strong evidence that they make a big difference when you’re using screens. If you spend a lot of time in the sun, it’s smart to think about getting high-quality sunglasses to protect your eyes from the harmful UV light that can cause eye problems.
Turning on blue light filters on your devices can make your screen more comfortable to look at and might help you sleep better. But scientists are still working to figure out if this truly keeps your eyes safe. Decrease the time you spend on screens and consider investing in a good pair of sunglasses!
If you are an IT professional or in a job that requires you to have long hours in front of a computer screen, get your eyes examined at least once every 6 months
