Hair dryer hurts eyes and cataracts? Medical repulsion: pure myth

Frequent use of hair dryers abroad may cause cataracts at a young age due to infrared electromagnetic waves or accidental blowing to the eyes? Ophthalmologists' refutation is purely a myth. At present, there is no relevant research to confirm the correlation between the two, but cataract is not a patent for middle-aged and elderly people, including high myopia, patients with metabolic diseases, long-term use of steroid eye drops due to eye allergy, or accidental impact on the eyeball due to external force. All four are high risk factors for early-onset cataract. It is suggested that people should treat according to symptoms in order to prevent cataract trouble as soon as possible.

According to the newspaper, a hairdresser used a hair dryer every day and used to hold it with his right hand. For a long time, the lens of his right eye near the hair dryer was degenerated and turbid, and he suffered from cataract at a young age. Wang Mengqi, an ophthalmologist, pointed out that the long-term use of hair dryers, whether accidentally blowing to the eyeball or suspected cataract caused by infrared electromagnetic waves and free radiation, is purely a myth, just as some people thought that putting a phone by the bed while sleeping would lead to brain cancer for a long time.

Dr. Wang Mengqi said that cataract is a kind of disease in which the lens of the eye is turbid, resulting in decreased vision, and in severe cases, blindness. Generally, with the increase of age, the incidence rate gradually increases. If you accidentally suffer from cataract at a young age, you may be suffering from high myopia, metabolic diseases, long-term use of steroid eye drops due to eye allergy, or accidentally hitting your eyeball due to external force, all four are high risk factors for early-onset cataract.

4 principles for preventing early-onset cataract

Dr. Wang Mengqi suggested that cataract is not a patent for middle-aged and elderly people. To prevent early-onset cataract, we should consult professional ophthalmologists for help according to different personal symptoms, living habits and working environment, and find the right way to prevent it.

High myopia: High myopia accounts for about 5% of patients with early-onset cataract. People with myopia over 6 degrees are prone to degeneration of protein in the lens early due to overuse of eyes, and then cause cataract lesions. In addition to the prevention of myopia from an early age, if you are already a high myopia, you need to follow up regularly, early detection and early treatment.

Steroid eye drops: Patients with atopic dermatitis, allergic conjunctivitis or iriditis who often use steroid eye drops should also be more careful. Long-term application of steroid eye drops can easily cause lens anterior capsule opacity and induce cataract. Remember not to buy proprietary medicines with unknown ingredients by yourself, and use eye drops correctly according to the doctor's advice.

Trauma and occupational factors: for example, when playing basketball, the lens is hit by a kidnapper, or the deliveryman is injured by the elastic belt of the bound goods carelessly, which will cause the lens to be damaged by the shock wave; In addition, professionals such as welders and lighting engineers must wear anti-ultraviolet goggles to avoid cataracts caused by ultraviolet B waves on the lens.

Metabolic diseases: For example, diabetic patients, if their blood sugar is not well controlled, it is easy to cause eyeball-related symptoms, such as cataract.
