Can take crocin 500 as and when needed.

Headache after constant use of any electronic screen is quite common. What needs to be evaluated after lockdown is your refractive error (spectacle prescription). Occasionally cervical spondylosis can be mistaken for headache and this happens because while using our mobile phones we are tilting our head down to see. Better would be to hold the screen at eye level or place it on a stand to prevent neck tilting. A past history of cold could result in sinusitis which results in a headache about and around the eye brows. For this do steam inhalation 10min at a time 2 times per day for 3-4 weeks. Also please google computer vision syndrome and follow the guidelines given to control/prevent it.

You maybe having dry eyes, or just in general are stressed. It could be lack of sleep or many other possibilities for causing a headache. As of now, if you have ever checked in the past few months and are sure you have no spectacle power, then you can start with basic cold compress, take frequent breaks while using the device.
