[0075] Based on the above scheme, the experimental data of optimizing the content of water-absorbing resin in the nutrient layer of the present invention are as follows:

[0076] Under the condition of keeping the content of self-heating powder unchanged, we found that the optimal addition amount of water-absorbing resin containing nutrient solution is 1g. The specific scheme of collecting water vapor by beaker is adopted. The specific test results are shown in Figure 3 .

[0077] In addition, the steam volume comparison test results of different brands of steam eye masks and the double-pack design steam eye mask of the present invention can be found in Figure 4 .
