Frequently asked questions

What causes eye strain?

Eye strain usually comes from long screen or close work, an uncorrected glasses prescription, or dry eye. It is uncomfortable but does not damage the eyes.

How do I relieve eye strain?

Take regular breaks using the 20-20-20 rule, blink fully and use lubricating drops, improve lighting, and have an eye test to make sure your prescription is correct.

Can eye strain cause headaches?

Yes. Tired focusing muscles and squinting can trigger headaches. If headaches persist despite breaks and the right glasses, see a clinician.
