Hi, you can continue using the Moistane eye drops for now. It's a good idea to get a dry eye evaluation done which includes a questionnaire and tests to determine the health of the 3 layers of your tear film.
Based on which layer/s is/are deficient, you'll be prescribed appropriate medication.
In case of severe dryness, you may consider getting lacrimal punctal plugs - either temporary or permanent ones.
Next Steps
Do use Genteal eye gel at bedtime in both eyes for now.

Since you are an IT professional, I assume your screen time will be considerably long. Try to follow the 20-20-20 rule: Every 20mins, take a break and look away from your screen at an object 20ft away and blink 20 times.
