Subject: Eye Appointment on Monday

Dear [Lecturers/Vice Principal/Hall Manager],

I hope this email finds you well. I wanted to inform you that I have an important eye appointment scheduled for Monday. As a result, I will not be able to attend school on that day.

I will make sure to catch up on any missed work and submit any assignments as soon as possible upon my return to school. I appreciate your understanding and support in this matter.

Thank you for your attention to this message. If you have any questions or concerns, please feel free to reach out to me.

Best regards,

[Your Name]
