(Original title: Users claim eye discomfort caused by Galaxy S8 iris scan)
According to the report of the British "Daily Mail" on June 12, two months after the much-anticipated Samsung Galaxy S8 entered the market, several users said that after using the iris to scan the eye pain or dizziness. Experts point out that eyes are sensitive to infrared radiation and that scanning with an iris may damage the eyes.
Since the accident of Note 7, the Galaxy S8 is considered to be saving Samsung. Samsung also seems to have devoted all its energy to the manufacture of smart phones with both smooth design and cutting-edge technology. However, a number of users said that after using an iris scan, the eyes feel sharp pain and dizziness. Some users have re-used fingerprint scanning. Although Samsung indicated that it is technically safe, studies have found that proteins in the eyes are very sensitive to infrared radiation and may cause cataracts.
A 2013 study used 15 New Zealand rabbits to examine the effects of infrared radiation on the eye. The results of the study showed that the enzyme activity decreased with increasing exposure to infrared radiation and indicated that the technique did cause corneal opacity, retinal burns, blood barrier breakdown, and delayed cataract. According to Janet Voke of Nova Southeastern University, infrared radiation increases the temperature of the anterior eye. The lens can only absorb a small amount of radiation, it is easy to cause damage to the eye.
Despite the user’s dissatisfaction, Samsung did issue a warning about using the Galaxy S8 iris scan and released a press release on the safety of new technologies in August. Also pointed out that when using iris recognition, the user should keep the screen at least 8 inches (approximately 20.32 cm) from the face.
Samsung said that the red light is an infrared LED that can achieve the best iris scanning range to ensure maximum accuracy, and said that the use of complete safety, there is no technology-related health effects.
There are rumors that Apple Inc. is also equipped with an iris scan in its upcoming iPhone 8, which makes many people wonder whether iOS users will experience the same discomfort. (Internship Compilation: Ju Suhui's reviewer: Li Zongze)
