An email to my co-workers

I am writing a new post because my old post is not correctly formatted.

I have an email that needs to be proofread. It's about informing my colleagues that I will put on a patch on my right eye. I imagine they will look at me weirdly and keep asking what's wrong with my eye. Therefor I want to send this email in advance.

Hi all,

I will have to cover my right eye more often because it is a healthy eye which has been working too hard to cover the left eye. This eye has gotten tired very fast lately and caused me a lot of pain during work, resulting a lower focus ability. The optometrist suggested me to wear the patch as often as I can to help me save my right eye and makes me feel better.

So I just want to know that in case you wonder when seeing me only with one eye.

Best,

Xuemei.
