Due to weather changes, excessive use of eyes and other factors, many people feel dry eyes, foreign body sensation, congestion and pain. Because I am worried that eye drops will do harm to my eyes and have no time to see an ophthalmologist, fever goggles have become the first choice to relieve visual fatigue and relax my eyes. However, there are also cases of "rollover" when using a fever blindfold. According to People's Daily, a 35-year-old Ms. Li in Wuhan recently bought an electric eye mask with a medicine bag from an acquaintance. After using it, her eyes stung and she was diagnosed with two corneal burns. Ms. Cao, 45, used a steam eye mask to sleep, causing eyelid allergy and minor burns. The seemingly safe and gentle heating eye mask actually hides risks, and consumers should polish their eyes when purchasing.

The temperature of the hot eye mask exceeds 45℃ for 5 minutes.

The reporter searched for heating goggles through the e-commerce platform. There are two main types of products for sale. One is electric goggles with built-in heating elements, which are mostly charged by usb and can be reused many times. Some products claim to have far infrared function and contain graphene components. Second, the chemical formula reactive eye mask or steam eye mask, customer service introduction, mainly rely on heating body, mostly iron powder, contact with air will heat up. The principle is similar to that of baby warming, and it is a disposable product.

The reporter searched on an e-commerce platform and found that there are more than 22,000 products under the electric eye mask entry, and the brand awareness of the products is limited. The price of a single set is around 200 yuan -600 yuan, and the brand with the highest monthly sales volume sells around 7000; There are more than 38,000 products under the entry of Steam Goggles, many of which are produced by well-known pharmaceutical companies such as Renhe, Yunnan Baiyao, Zhenshiming and sharping. The unit price is 2 yuan -8 yuan, and the monthly sales volume of Renhe and Zhenshiming flagship stores is nearly 50,000 boxes. The online sales audience of steam goggles is relatively large. To this end, the reporter bought Kao steam eye mask, real steam eye mask and the joint steam eye mask of the Forbidden City and famous products for temperature evaluation.

The reporter found that five minutes after unpacking, the temperatures of Shi Ming, Kao and Mingxiaoyou products reached 46.9℃, 46.5℃ and 45.2℃ respectively. After 20 minutes, the body temperatures were 33.3℃, 34.2℃ and 39.5℃ respectively. The duration of fever is about 25-30 minutes for famous steam eye mask, 20-25 minutes for rare steam eye mask, and 0/5-20 minutes for Kao steam eye mask. If you use a steam eye mask with a fever close to 40℃ for nearly half an hour, the skin around your eyes may become red or even slightly burned.

Control the duration of hot compress steam eye mask.

Wang, a teacher of educational chemistry at Jushi University, said that steam goggles mainly generate heat through the oxidation reaction of metals. When the products leave the package, the reaction begins when they come into contact with oxygen in the air. In this process, the reaction speed is beyond the control of consumers, and once it starts, it can't be stopped, and even the local violent reaction of the product leads to a rapid increase in temperature. Unless the product is isolated from oxygen, the reaction can only be terminated. In the evaluation, the heating elements of Zhenshiming and Kao steam eye masks use metal temperature control plates instead of iron powder, which makes the heating more uniform and avoids the leakage of fillers such as iron powder. Consumers should also pay attention to the heating speed when purchasing steam goggles to avoid using products that react too fast or overheat.

It should also be noted that the longer the steam eye mask is hot, the better. Improper use can easily cause low temperature burn of eye skin and corneal burn. In the evaluation, the heating time of Kao steam eye mask is closest to the suggested time of 10 minute, while the heating time of other steam eye masks is 2-3 times of the suggested time. Consumers who are used to wearing steam goggles to sleep should pay attention to controlling the use time.

Eyes are often dry and itchy, so seek medical attention in time.

Many bloggers will use descriptions to relieve dry eyes, itching and fatigue when recommending steam eye masks. Some steam eye masks have also launched a series of products of "Chinese medicine steam eye mask", claiming to add ingredients such as cassia seed, lutein and agarwood.

Dry eyes are not necessarily lack of water. Professor Huang Zhongwei from the Department of Ophthalmology, the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, said that the steam eye mask with steam fumigation and Chinese medicine ingredients is not the first choice for the treatment of dry eye, and the symptoms of eye discomfort are caused by timely medical treatment and medication.

Professor Huang pointed out that dry and itchy eyes can be treated with nourishing eye drops, such as Beifushu, tears and sodium hyaluronate. In the case of obvious inflammation, anti-inflammatory eye drops should be added; However, eye drops should not be used too frequently, and it is best not to exceed 6 times a day, otherwise it will aggravate symptoms such as dry eye.

Professor Huang suggested that in addition to eye drops, you can also try to do your own meibomian gland massage, hold your eyelids with your thumb and forefinger, gently press hard, squeeze out blisters around your eyes, and squeeze out inflammatory secretions in meibomian glands. Do it twice a day for about one minute each time. Patients can wet and hot compress their eyelids every morning and evening, but each hot compress time is about 10 minute, so attention should be paid to eyelid cleaning.

Don't smoke and drink, but drink more sugary drinks and don't "eat spicy food"; Eat more fresh fruits and vegetables, drink more water, and avoid using your eyes too much.
