[0063] Example 7 This example is to evaluate the use effect of the traditional Chinese medicine fumigation bag prepared in Examples 1-3.

[0064] To verify the use effect of the traditional Chinese medicine fumigation bag of the present application, the fumigation bags prepared in Examples 1-3 were selected for effect evaluation on people who often use their eyes (such as subjects who experience visual fatigue due to long-term computer use and people who stay up late watching mobile phones). The test population was randomly divided into a test group (30 people) and a control group (30 people), and the test group was further divided into three groups: a first test group (using the fumigation bag prepared in Example 1), a second test group (using the fumigation bag prepared in Example 2), and a third test group (using the fumigation bag prepared in Example 3); the control group used a common warm water atomizer without medicine.

[0065] The specific use method is as follows: ① The traditional Chinese medicine fumigation bags prepared in Examples 1-3 were respectively placed in the medicine bin of an eye atomizer, and 80 mL of clean water was added to fully soak the medicine bags.

[0066] ② The eye atomizer was started, and the internal heating module of the instrument heated the medicine liquid to 70℃ to generate fine and constant-temperature medicine mist.

[0067] ③ User wears the matching eye mask of the atomization instrument, aims the mist outlet at the eyes and the surrounding area, closes the eyes for atomization fumigation, each time for 20 min; during the atomization process, the drug mist penetrates through the skin and meridians around the eyes, plays the roles of clearing heat and brightening eyes, dispelling wind and heat, and relieving visual fatigue.

[0068] ④ Use once a day, and continuously use for 7 days as a course of treatment.

[0069] ⑤ The same fumigation bag can be used once within 24 h, and when used again, water needs to be added and the atomization instrument needs to be started.

[0070] Evaluation method: Subjective scoring method: The visual analogue scale (VAS) is used to evaluate the degrees of “dry eyes”, “sore eyes”, and “swollen and painful eyes”, and the subjects score their own degrees of “dry eyes”, “sore eyes”, and “swollen and painful eyes” on a scale of 0-10 (0 represents no discomfort, and 10 represents the most severe discomfort). Finally, the average score of each group of subjects is calculated.

[0071] Objective examination index: Uncorrected visual acuity (UCVA) records the best visual acuity of the subjects without wearing glasses; tear film break-up time (BUT) evaluates the stability of the tear film and measures the time from the appearance of the first dry spot on the tear film surface after blinking. Finally, the average value of each group of subjects is calculated.

[0072] Evaluation time: Evaluation is carried out before the use of the traditional Chinese medicine fumigation bag (baseline), after the use of one course of treatment (7 days), and after the use of two courses of treatment (14 days). The evaluation results are shown in Table 1.

[0073] Table 1 As can be seen from Table 1, all the test groups are significantly better than the control group in improving the symptoms of “dry eyes”, “sore eyes”, and “swollen and painful eyes” and prolonging the tear film break-up time (BUT), and the improvement effect is more obvious with the increase of the treatment course. At the same time, the uncorrected visual acuity (UCVA) of the subjects in all the test groups shows a slight upward trend. This shows that the traditional Chinese medicine fumigation bag of the application not only can effectively relieve the symptoms related to dry eye syndrome, but also can significantly improve the stability of the tear film, thereby effectively improving the dry eye state.

[0074] Example 8 This example is to evaluate the use effect of the traditional Chinese medicine fumigation bag prepared in the above Examples 4-5.

[0075] To verify the use effect of the traditional Chinese medicine fumigation bag in the present application, the fumigation bags prepared in Examples 4-5 are selected to evaluate the effect on people who often use their eyes (such as subjects who have visual fatigue caused by long-time use of computers and people who stay up late to watch mobile phones). The test population is randomly divided into a test group (30 people) and a control group (30 people), wherein the test group is further divided into three groups: a fourth test group (using the fumigation bag prepared in Example 4), a fifth test group (using the fumigation bag prepared in Example 5), and a sixth test group (using the fumigation bag prepared in Example 6); the control group uses a common warm water atomizer without medicine.

[0076] The specific use method is as follows: ①The traditional Chinese medicine fumigation bags prepared in Examples 4-5 are respectively loaded into the medicine bin of the eye atomizer, and 80 mL of water is added to fully soak the medicine bag.

[0077] ②The eye atomizer is started, and the internal heating module of the instrument heats the medicine liquid to 70℃ to generate fine and constant-temperature medicine mist.

[0078] ③The user wears the matching eye mask of the atomizer, aims the mist outlet at the eyes and the eye area, closes the eyes to perform fumigation and steaming, and each time lasts for 20 min; during the atomization process, the medicine mist penetrates through the skin and meridians around the eyes to play the roles of clearing heat and brightening eyes, dispelling wind and heat, and relieving visual fatigue.

[0079] ④It is used once a day, and a course of treatment is 7 days of continuous use.

[0080] ⑤The same fumigation bag can be used again once within 24 h, and water needs to be added again and the atomizer needs to be started for the next use.

[0081] Evaluation method: Subjective scoring method: The visual analogue scale (VAS) is used to evaluate the degrees of “dry eyes”, “sore eyes”, and “swollen and painful eyes”, and the subjects score the degrees of “dry eyes”, “sore eyes”, and “swollen and painful eyes” on a scale of 0-10 (0 represents no discomfort, and 10 represents the most severe discomfort). The average score of each group of subjects is finally calculated.

[0082] Objective examination index: uncorrected visual acuity (UCVA) is recorded, naked eye visual acuity (UCVA) is recorded, and the best visual acuity of the subjects without wearing glasses is recorded; tear film break-up time (BUT) is evaluated, and the stability of the tear film is evaluated, and the time from the appearance of the first dry spot on the surface of the tear film after blinking is measured. The average value of each group of subjects is finally calculated.

[0083] Evaluation time: evaluation is performed before the use of the traditional Chinese medicine fumigation bag (baseline), after the use of one course of treatment (7 days), and after the use of two courses of treatment (14 days). The evaluation results are shown in Table 2.

[0084] Table 2 As can be seen from Table 2, the treatment scheme of the present application (Examples 4, 5, and 6) has a significant effect on dry eye, and is superior to the conventional control treatment; Example 4 (the fourth test group) is the optimal formula or process, and performs best in terms of symptom relief, vision improvement, and tear film stability improvement; the treatment effect is enhanced with an increase in the treatment course, and the effect is more stable after two treatment courses; the scheme can effectively improve the ocular discomfort of dry eye patients, improve the visual quality, and enhance the tear film stability.
