Dear, fingers counted, we have been together for 30 years, looking back on these 30 years, there are wind and sunshine, there are also storms, and we always know each other, never leave each other. I remember our third year together, although we both look at things at the same time, regardless of distance, are clear, but when only I look, is foggy, no matter how hard I, even the doctor put on my glasses, still no improvement, the doctor said I was amblyopic, I was scared, in my most fearful time, you came forward, told me not to worry, in order to let me In order to get better training, you willingly accepted the fact that you were covered for 6 hours a day, silently endured the darkness, and kept cheering me up to keep gazing and training with activities such as jigsaw puzzles, drawing and beading. With your encouragement and companionship, these trainings are no longer boring and uninteresting. Gradually, I could see more and more clearly until I could see as clearly as you. This training was three years! Without you, how could I have made it through. I remember our sixth year together, our master went to a party after returning home, I began to feel red, itchy and swollen, and sticky yellow discharge, perhaps we are too close, perhaps I touched something and touched you, the result you also became the same as me, the doctor said, this is an acute conjunctivitis, very contagious. For a week, we jointly endured the frequent impact of eye drops, finally, the red slowly receded, not itchy and not swollen. After this ordeal, the two hearts were closer together. I remember our twelfth year together, we discovered a sad fact at the same time, the blackboard in the classroom could not be read, we had to face the reality is that we both became myopic. The doctor fitted us with keratoplasty lenses, and for the next eight years, every night and every morning, we wore and removed the lenses together, and finally at the end of our twentieth year, the doctor said, “Well, you don’t need to continue wearing them because our prescription has stabilized and will not progress anymore. What a happy thing that was. Time flies, we came to the twenty-eighth year, those years, we spent a large part of the time in front of the computer, we both spirits are getting worse and worse, often feel dry and astringent, sore and swollen discomfort, listless, even if mutual comfort and mutual encouragement, but not back to the former state of vitality. Finally, we found the answer at the doctor’s place, and it was all because of dry eyes. We listened to the doctor’s advice and started to use artificial tear drops, minimize the use of computers, cell phones and iPads, not to stay up late, and the doctor also put a small plug in each of us, and we felt much better. This is the thirtieth year, although we can not look at each other, not even hug, but I know that you are always beside me, every picture of beauty, we will feel at the same time. In the years to come, we will still be together, and together we will perceive the beauty of the world, and we will also experience more trials, like cataracts and macular degeneration, but, as long as we are with you, these are nothing. Darling, remember our favorite poem? Let me once again, with the most affectionate voice to read to you: “We share the cold tide, wind and thunder, thunder; we share the mist and mist, rainbow and neon, as if forever separated, but lifelong together, this is the great love”! Yes, that’s right, we are the left eye and the right eye.
