Low Resolution Screens: Using old monitors and low resolution screens are hard on the eyes, and can cause straining. For better results, upgrade to a higher resolution.

Mouse too far away: having your mouse too far away will make you lean closer to your screen, increasing focusing strain

Sitting on a bad chair: This can affect your focusing. Ensure that your back is always supported, so you can sit upright and at a comfortable viewing distance from your screen

Turtling: this involves sitting with your back rounded, chin jutting forward and head tilted back to get close to your screen. Please avoid this. If you can’t see your screen clearly with good posture, visit an eye doctor.
