英文小作文：

My Eyesight My Eyesight is very important to me, and I take good care of them by wearing glasses and contacts when necessary. However, with age, my eyesight has become a bit troublesome because of presbyopia. I have been experiencing difficulty seeing things up close and far away at the same time, which has caused me to rely on my glasses or contacts more often than I would like to. But now, thanks to corrective surgery, my eyesight has improved significantly and I am able to see clearly without glasses or contacts. I am very grateful for this surgery because it has given me back my independence and confidence in my eyesight. I hope that everyone can experience the same thing and have clear vision for a lifetime.
