Your symptoms are classic signs of eye strain and dry eyes from prolonged focusing. To relieve the burning sensation, I recommend over-the-counter lubricating eye drops (artificial tears) containing generic ingredients like carboxymethylcellulose or polyethylene glycol, preferably preservative-free. For the mild headache, temporary relief can be found with generic pain relievers like ibuprofen or acetaminophen. Additionally, try the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds to rest your eyes. If your symptoms persist or worsen, please consult an eye care professional for a routine vision check.

Since your current treatment isn't working, it is important to consult your eye doctor for a re-evaluation before starting new medications. Continuous watering is often a reflex response to underlying dry eyes, allergies, or a blocked tear duct. \n\nWhile waiting for your appointment, using preservative-free artificial tears (lubricating drops) can help soothe irritation safely. Avoid over-the-counter redness-relief drops. Depending on the diagnosis, your doctor may suggest prescription anti-inflammatory drops (like cyclosporine), antihistamines, or warm compresses. Rest assured, this is a very common and highly treatable issue once the exact cause is identified.

Your symptoms point to digital eye strain and temporary dry eyes from prolonged screen use. Since you wear -3.0 D glasses, close-up mobile use can easily fatigue your eye muscles. For immediate relief, I recommend over-the-counter preservative-free lubricating eye drops (artificial tears) used 3 to 4 times daily. Additionally, practice the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds to relax your focus. Ensure your screen brightness is adjusted and blink frequently. If blurry vision persists after resting, please consult an eye specialist to verify if your prescription needs adjusting.
