You probably have to make more use of computer ergonomics, however for now I would recommend you apply the 15-15-15 rule which says after 15 minutes of working look at a distance 15 feet away for 15 seconds and you should be fine. If symptoms persist please see an optometrist nearby for better assessment and evaluation.
Am glad you could pass through, thanks for reading bro
Wow. This is a great a gem. Will practice and give you a feedback
