Help! My Child Has Online Classes! Do They Need Blue Control Glasses?

If you’ve found yourself saying, “My child spends more time on screens than on the ground!”, you’re not alone. With online classes, virtual tuitions, Zoom birthdays, and YouTube “study breaks,” kids today are practically glowing from all that screen time.

And now, you’re hearing about blue light and seeing ads for “blue control glasses”. The big question:

Are they really needed? Or is it just another techy trend?

Let’s dive in and clear up the blue confusion — with a dash of fun and a pinch of parental sanity!

First, What Is Blue Light Anyway?

Think of blue light as one of the many colors in the light spectrum, just like red, green, and purple. It’s not evil — in fact, it’s naturally found in sunlight and helps us stay awake and alert during the day.

But digital screens — like laptops, tablets, and phones — also emit blue light. And in large amounts (especially at night), it may mess with our body’s natural clock — the circadian rhythm — by tricking the brain into thinking it’s still daytime.

No wonder bedtime is now a nightly negotiation!

Will Blue Light Damage My Child’s Eyes?

Here’s the truth:
As of now, there’s no solid scientific evidence that blue light from screens causes physical damage to the eyes like vision loss or retinal problems. The blue light from a screen is far weaker than the blue light from the sun.

BUT (yes, there’s always a “but”)…

Too much screen time can still cause:

  • Eye strain

  • Dry eyes

  • Blurry vision

  • Headaches

  • Trouble sleeping

Collectively, this is often called Digital Eye Strain or Computer Vision Syndrome. Sounds fancy, but it’s basically your eyes saying: “Give us a break, please!”

Enter: Blue Control Glasses

Blue control (also called blue light blocking) glasses are specially coated to filter out some of the blue light from screens.

While they don’t give your child superhero laser vision, they can:

  • Slightly reduce glare

  • Help reduce screen-related eye strain

  • Possibly improve sleep when used in the evening

But—and here’s the plot twist—they’re not mandatory for every child who uses a screen. Think of them like a raincoat on a drizzly day: helpful, but not life-saving.

So, Does My Child Need Them?

Ask yourself:

  1. Is your child spending more than 2–3 hours daily on screens for online school, homework, AND entertainment?

  2. Do they complain of tired eyes, headaches, or blurry vision after screen time?

  3. Is sleep becoming difficult—especially if screens are used before bed?

If you said yes to one or more, blue control glasses may help. But they’re just one piece of the puzzle. There are other super-effective (and sometimes free!) tools too.

Eye-Saving Habits That Work Wonders

Follow the 20-20-20 Rule
Every 20 minutes, look at something 20 feet away for 20 seconds. It’s like a coffee break—for your child’s eyeballs.

Blink, blink, blink!
Kids tend to blink less while staring at screens. Remind them to blink to keep eyes moist and avoid that dry, gritty feeling.

Proper screen setup
The screen should be about an arm’s length away and slightly below eye level. Not nose-to-screen like they’re decoding alien messages.

Use night mode or screen filters
Most devices now come with “night shift” or “eye comfort” settings that reduce blue light and give the screen a warm glow. Use them!

Limit screens before bed
Try to keep screens off at least 1 hour before sleep. This one’s tough—but worth it!

What If My Child Already Wears Glasses?

No worries! Blue control lenses can be added to prescription glasses too. Just ask your optometrist. Some lenses even combine blue filtering with anti-glare and scratch resistance. Fancy, right?

Bottom Line

Blue control glasses aren’t magic. But if your child is glued to a screen for hours each day (thanks, online classes!), they can help reduce eye strain and improve comfort.

However, nothing beats healthy screen habits, regular eye breaks, good posture, and enough offline play time. It’s all about balance — between blue light and real sunlight!

So next time your child squints at the screen and says, “My eyes feel weird,” don’t panic. Try a combo of blue control glasses and smart screen strategies. Their eyes—and you—will thank you.

Now go on, give those eyes a break… and maybe yours too! 😉
