Dear Cathy,
I’m glad to have received your letter.
From your letter, I learnt that your eyesight has decreased recently. It’s my pleasure to give you some suggestions on how to protect your eyes.
First of all, you should have a proper reading posture. Don’t read in bed, as it can do great harm to your eyes. Meanwhile, there should be plenty of light while you are reading. Besides, avoid watching TV, playing computer games or mobile phones
for a long time. What’s more, it’s important for you to do eye exercises twice a day and get a good sleep at night. Doing outdoor activities and looking out of the window to enjoy green trees and grass during break times are also good ways to make your eyes relaxed.
If you follow my suggestions above, your eyesight will be sure to improve gradually. I’m looking forward to receiving good news from you!
Yours
