Dd 14. VDU headaches from online lessons

How do we reduce this?

5 hours a day. Sometimes for 2 consecutive hours. Then she wants to talk to her friends on her phone chats in the evening. I’m loathe to remove that as it’s her only social contact.

Special glasses?

Might need an eye test and definitely needs eye breaks. She should look away from the screen and focus on a distant point, out the window or on a far wall for a couple of minutes every 20 minutes or so to give them a break.

You can get special glasses to use that filter out the blue screen effects too like these- https://babiators-uk.com/collections/babiators-blue-light-screen-saver-glasses?gclid=EAIaIQobChMI4P67LSo7gIVD5ntCh0JvQDyEAAYAiAAEgJXwwDBwE#erid5200732

Email the school, tell them what’s happening and ask them to reduce the length of the lessons.

A lot of schools are dropping to 45 minute lessons so they’re not back to back and kids can have a movement break in between.

Try downloading mystudybar and using the screen tint under the reading option, or if on a mac there is a screen tint. Having a different colour screen might lessen the eye strain. Start with her favourite and experiment until you find one that works.

I got mine blue light glasses from. Amazon. They have definitely made a difference.

Does pc have a blue light filter?
Turn brightness down on monitor.

If she's running a compute with Windows 10, you can switch it to the 'night light' setting, which has less blue light. I turn down the strength, so it's not too warm for daytime use, and it certainly helps reduce my headaches. iPhones also have a 'Night Shift' setting.

You can download software to filter out the blue screen l think

I think she’s got windows 10. She’s refused point blank to wear glasses.

I'm in a country where the kids have been online since last March. (I'm a teacher) A lot of the kids have had their glasses prescription changed, and I definitely need to.
It might not actually be the screen but posture.
Have her eyes checked, and make sure if she's using a laptop that it's raised up so she's not cricking her neck downwards- even slightly for hour after hour, day after day has a detrimental effect. I have a lever arch file under mine and DD who uses a tablet has a tablet stand thingy so it's basically suspended in the air in front of her.

It’s a desk top, so should be level with her eyes.

Are opticians open?

Yes, opticians are open for "essential services" so basically if you're having problems and are doing some routine work as well as there was a massive backlog after the last lockdown.

The top of the screen should be level with her eyes so that she's always looking down at about 50cm . She also needs to be having at least a 10 minute break every hour looking at something further away.

The blue blocking glasses just reduce glare rather than overexcitation of the visual system and you can do that by turning down the brightness.

From an optometrist's point of view, it is not good for developing eyes to be looking at a screen all day.
