Dry eye­ occurs when your eyes do not produce­ adequate tears or the­ tears are poor quality. It can lead to wate­ry eyes, blurred vision, and a burning se­nsation. Potential causes include aging, ce­rtain medications, or extende­d screen time. To he­lp alleviate symptoms, use artificial te­ars, avoid smoke exposure, and take­ breaks from screens. Additionally, fre­quent blinking can help kee­p your eyes moisturized.

Both your eyes are mostly fine. A corneal erosion can be dangerous and cause pain and sensitivity to light. Even if you have perfect eyesight, you may need to wear special glasses that will protect your eye from an even greater injury. These glasses can be used to stop more erosions from happening. 

In that case please get it checked thoroughly by a good physician to see if there are still any concerns due to acid.

Red eyes are common and can happen for many reasons, like a stuffy nose, dust, tiredness, or chlorine. Sometimes, conditions like arrhythmia or long periods of staring at screens can also cause red eyes. To help, you can use artificial tears to keep your eyes moist. If your eyes still feel irritated, taking a break and resting them is a good idea.
