7 There are at least a few hundred poems on eyeglasses from the Qing dynasty. This assumption of the total number is based mainly on the search results of the Zhongguo jiben gujiku 中國基本古籍庫 (Database of Basic Chinese Classical Texts): of the approximately 800 collected works of Ming scholars, there are only two poems on eyeglasses, and of approximately 1,200 collected works of Qing scholars, there are about 100. However, many more collected works by Qing scholars are not included in this database, so the actual number of poems on eyeglasses should be greater, but it should not exceed a thousand.

20 The term “tadpoles” (kedou 蝌蚪) refers to overly complex ancient graphic designs of characters and also implies “small-sized characters”. This line means that with eyeglasses, the poet could study those difficult texts which he left behind due to the decline of his vision.

21 This line means that the poet is devoted to reading and does not realize that time passes quickly.

22 The term “ribbons and dance” refers to the first stanza of the poem “Shu in the hunting-fields” in the Book of Songs: “Shu in the hunting-fields / Driving his team of four, / The reins like ribbons in his hand, / His helpers leaping as in the dance!” (叔於田, 乘乘馬. 執轡如組, 兩驂如舞). For the translation of the complete poem, see Arthur Waley (trans.), The Book of Songs (New York: Grove Press, 1996), 66–7.

29 The term shaoliao 燒料 (sintered material) refers to a type of material that is similar to, but not as good as, glass. However, the term mizhi 米汁 refers to miganshui 米泔水 (water used to rinse rice); in this case, it probably refers to the colour of the eyeglasses with a clear indication of opaqueness, but it may refer to part of the manufacturing process.

30 This line could also be translated as: “the price is decreased as [the colour of the lenses] fades”.

The first poem is the same in these two works, but the second poem has two versions, where the wording is different in the first and third couplets. I think the poem in Huangqing wenying 皇清文穎 (Literary Masterpieces of the Imperial Qing) is a later version, because some imprecise expressions in the other version have been corrected. Yang Xuan 楊瑄 (fl. 1694–1723) also composed a set of three poems on receiving a pair of eyeglasses from Emperor Kangxi. See Zhang, Huangqing wenying, vol. 465, 447.

49 The “Mirror of the Mind”, a Buddhist concept, is to reflect the Truth only if it is kept clean.

50 “Autumn waves” is a metaphor for one's clear vision.

51 The term “a fly's head” (yingtou 蠅頭) refers to characters written in small size, which are as small as a fly's head.

53 It is also worth noting that Liu Fenggao tried in the third couplet to please the emperor in another way. “To put [eyeglasses] on the eyes, / through [it one] can gaze in quietude” (即以謀於目, 因之静可睋), is composed imitating the “Imperial Style” (yuzhi ti 御製體) of Emperor Qianlong. For remarks on Emperor Qianlong's poetic style, as well as those imitational works written by the emperor's literary aides, see Qian Zhongshu 錢鍾書, Tanyi lu 談藝錄 (Beijing: Sanlian shudian, 2001), 205–18, 545–9, 553–5, 556–73.

54 Glass is “dry” because, in the Chinese understanding, it has the attribution of “fire”, while crystal is “tender” because it has the attribution of “water”.

55 The character bi 蔽 has two meanings, “being obscured” or “being deceived”, and Emperor Qianlong is playing with both meanings here.

61 There was probably a string tying together the two lenses. For a brief survey of different types and accessories of eyeglasses, see Li, “Ming Qing zhiji Xiyang yanjing zai Zhongguo de chuanbo”, 40–1.

63 This self-annotation shows Yuan Mei's own understanding of the following line in Xunzi, translated by John Knoblock:

In some earlier versions of Xunzi, the term zhanyan 瞻焉 (to see one's forehead) is written as zhanma 瞻馬 (to gaze a horse), but some commentators believe ma 馬 is a misprint of yan 焉, and yan means “forehead” (same as yan 顏). However, in Wang Xianqian's 王先謙 (1842–1917) annotation, he reads zhanyan 瞻焉 as zhanma 瞻馬, so this line suggests that the King cannot see small things clearly, but can only see big things (e.g. a horse) placed right in front of him – this indicates short-sightedness. For the translation and some notes on different annotations of the original line, see John Knoblock, Xunzi: A Translation and Study of the Complete Works (Stanford: Stanford University Press, 1988), vol. 1, 204, 295. For the original line and different annotations, see Wang Xianqian 王先謙, Xunzi jijie 荀子集解 (Beijing: Zhonghua shuju, 1988), vol. 1, 74.

However, Yuan Mei's understanding of this line is different from above interpretations. In a passage entitled “Illnesses of the Present Day which Appear in Ancient Books” (Jin jibing xian gushu 今疾病見古書), Yuan Mei writes:

Yuan Mei reached the conclusion of short-sightedness from a different approach. However, he did not give a logical explanation as to why the King seeing a small bird is proof that the King is short-sighted. But if one can clearly see a small bird in the distance, would it not suggest that the person is far-sighted?

65 Yuan Mei's writings, in both his poetry and poetic criticism, are full of exaggerations and mistakes. For a detailed discussion of this issue, as well as Yuan Mei's habit of showing off, see Qian, Tanyi lu, vol. 2, 768–72.

68 Qian Weicheng, who came first in the palace examination in 1745, was the Provincial Education Commissioner of Zhejiang (Zhejiang xuezheng 浙江學政) at that time.

69 Qian Weiqiao, a younger brother of Qian Weicheng, received the title of Provincial Graduate (Juren 舉人) in 1762.

70 There are two versions of this linked verse: the version recorded in Qian Weicheng's poetry collection is slightly different from that in Qian Weiqiao's collection.
