Thank you for your query at DoctorSpring.com
The eye sight being dimmer in one eye must be from birth ( one eye being lazy eye) , if cleaning powder enters the eyes it will cause pain redness & severe irritation , since thats not the case so nothing to worry ,
Now the brighter eye getting dimmer, it can be because of either some infection or allergy. If the brightness is significantly down then visit the ER. You just need to observe, if it stays the same without any deterioration then within a couple of days it will be okay. If the brightness preogressively comes down, then you can get an Ophthalmology consult.
Feel free to discuss further,

Patient replied :
The dimness is not significant, I will keep an eye on it. My eye has also been a bit irritated - some redness (small red veins) and feels a bit scratchy. I am using artificial tears. Any reason to be concerned about a bit of redness and irritation?
The redness and irritation could be due to allergies, or dry eyes.
Since you're using artificial tears you do not have any reason to worry.
It should resolve in a couple of days.
