Continuous eye strain from screens is very common. Since your current drops aren't helping, try switching to preservative-free artificial tears containing sodium hyaluronate or a higher concentration of carboxymethylcellulose, which can be used frequently without irritation. For longer-lasting relief, a thicker lubricating eye gel at night can be highly effective. Also, practice the 20-20-20 rule, every 20 minutes, look 20 feet away for 20 seconds, and remember to blink consciously. If the pain persists, please consult an eye specialist to rule out any underlying vision changes or dry eye syndrome.
