Under normal circumstances, ⿰目力 is a variant form of the character "助," as described in the 异体字典 (p1,https://dict.variants.moe.edu.tw/dictView.jsp?ID=4126):
"Characters derived from the phonetic component 且 (qiě) typically follow a left-radical, right-phonetic structure, with rare exceptions of right-radical, left-phonetic arrangements. Consequently, in variant forms of 助, the component 且 is often miscopied as 目 (mù). This error is most frequently observed in the 敦煌俗字譜. 字鑑 and 正字通 both note it.This demonstrates that the use of 目 in vulgar forms was widespread, hence its inclusion here."
Evidence 3 is drawn precisely from Dunhuang manuscripts. This form appears extensively in origal books, such as the 文苑英華 and 説文通訓定聲, as shown in p2 ~p5. Another example is Evidence 2, which cites six instances in the 尚書注疏彙校 (Chief Editor Du Zexun杜澤遜, Zhonghua Book Company, 2018) where "助" is written as "⿰目力" in collation notes for the Song dynasty "Eight-Line Edition" (abbreviated "八") and the Song dynasty Wang Pengfu edition (abbreviated "王") of the 尚書注疏.

A notable exception is Evidence 1 from the 孫臏兵法校理, where the character ⿰目力 appears in the "Sun Bin's Art of War Bamboo Slips from the Yinqueshan Han Tombs.", as shown in the facsimile copy of the original bamboo slips(p6).
The 孫臏兵法校理 describes this character as "composed of 目 and 力." The author refutes the interpretation in (銀雀山漢墓竹簡) 孫臏兵法 (Cultural Relics Publishing House, 1975, CN 7068-339), which "suspected it should be read as 冒 (mào)," arguing instead that it is an abbreviated form of the character "瞗 (diāo)"(p7).
