1, the main way of eye washing
There are many ways to wash and protect, such as opening your eyes, closing your eyes and squinting. It seems that all the tricks are useful. Open-eye washing, also known as eye dry cleaning, is eye drops, and then gently wipe the upper and lower eyelids with a cotton swab. Close your eyes and wash your eyes, also known as wet eye washing, which is to stimulate your eyelids with water with moderate temperature. As for squinting and eye washing, generally only star-rated beauty salons have this kind of service, which is generally divided into two types, one is eye washing for nursing and the other is eye washing for treatment.
2. Do you need to wash your eyes?
1. In medicine, there is no such thing as "eye washing". Generally speaking, only patients who need eye surgery, eye trauma caused by acid and alkali burns or serious eye diseases such as conjunctivitis and corneal foreign bodies need to be washed with normal saline or disinfectant, which is called "conjunctival sac washing". Eye washing requires very high environment, technology and medicine. If the disinfection of eye washing equipment is not strict, it will also cause eye damage or infection with conjunctivitis, trachoma and other eye diseases. Most eye washes consist of artificial tears, cellulose and some vitamins. Some will add some things with nutrients, sterilization and anti-inflammatory components, and anti-corrosion components. Its composition is far from natural tears, and their pH, pH and osmotic pressure are also different.
2. For healthy eyes, tears are the best eye care solution, because tears can keep the cornea moist and clean and protect the conjunctival sac. The chemical composition of tears is very complicated. In addition to water and electrolyte, there are nitrogen-containing substances, sugars, organic acids, vitamins, enzymes, lipids and other components. Lysozyme is a natural antibacterial substance, and many immunoglobulins perform nonspecific and specific immune functions. These are unmatched by artificial eye washes.
3. The harm of frequent eye washing
If the tear secretion is insufficient and the quality and quantity of tear film are abnormal, it will cause dry eye, also known as corneal dryness and conjunctivitis. Symptoms are dry eyes, itching, burning sensation and fatigue. For example, indiscriminate use of eye drops, indiscriminate use of eye drops, and indiscriminate washing of eyes can not only protect the eyes, but also easily cause harm to the eyes!
4, eye care precautions
Summer is sultry, and the water on the eye surface evaporates quickly. Pay attention to replenish water and eat more soy products, fish, milk, vegetables, Chinese cabbage, spinach, tomatoes and fresh fruits, which will help protect your eyes. Pay attention to eye hygiene. Whether reading a book or using a computer, don't concentrate for too long. You should blink more consciously, rest every 30 to 40 minutes 10~ 15 minutes, look into the distance and let your eyes relax fully.
