Magnifying Glasses
Has anyone ever developed or experienced any side effects from using magnifying glasses for reading?
My dad has been having a good amount of issues with these.
Yes. If you focus too long, you could end up with a headache, blurred vision, spots in your vision, etc. It could also hurt your eyesight pretty bad if you do it too often.
Tell him to take abreak now and then, and he should feel much improved.
