The majority of people will put isolation or sunscreen on their skins when they go out, whether it is sunny or cloudy, but what about the eyes? According to a survey by the American Optometric Association (AOA), more than 80% of Americans wear sunglasses in summer but less than a third in winter. Even in winter or cloudy, 80% of ultraviolet rays still pass through the clouds. Most people ignore this. Ultraviolet rays can damage the eyes and cause diseases, and the most serious cause blindness.
From the point of view of eye protection, the earlier you begin to develop the habit of wearing sunglasses, the young people in European and American countries will almost always wear sunglasses when they go out, not just to pursue fashion and good looks, but to focus on taking care of the eyes. The concept of sun protection is also partly because their eye pigments are lighter than that of yellow races. The light transmittance of the eyes is high, and the stimulation to strong light is large, which deepens the habit of wearing sunglasses. Another important reason is that the younger people with the clearer of the cornea and crystals, the photoreceptor cells are more sensitive and severe the damage will be if there is no proper protection; The sooner you begin to do eye protection, the more you can delay the occurrence of eye diseases in the elderly.
The crystal located in the middle of the eye is responsible for letting light through and adjust to see far and near. On average, when a person is over 50 years old, the crystal will gradually become cloudy and cause cataracts. If the eyes are not in well-protected situation, too much strong ultraviolet light enters the crystals, which increases the severity of cataracts. In recent years, outdoor sports have flourished, but the trend of wearing sunglasses has not been generalized. Without glasses protection, activities under strong light and long-term use of 3C products will cause the eyes to absorb excessive ultraviolet and blue light, resulting in excessive load of cystal. Therefore, the age group of patients suffering from cataracts has a gradually downward trend.
2. Macular lesions
There is a special part called "macular part" in the center of the retina directly behind the eyeball. If you are exposed to strong ultraviolet rays for a long time and use 3C products such as mobile phones, tablets or computers at close range, it will accelerate the aging of retinal photoreceptor cells. The posterior macula is damaged early and develops lesions.
The retina is located in the deepest layer of the eye, which is an important factor that affects imaging. When light enters the retina, it will form an image of what is seen in the eye, but like macular disease, if under excessive ultraviolet radiation without sunglasses protected. The retina can also cause disease, the most serious cause blindness.
4. Light damage keratitis
The outermost layer of the cornea is a thin film, which provides most of the refractive power of the eye and serves as the first line of defense for the eye. With the prosperity of outdoor sports, plus the summer season, many people like to go to the beach or even engage in water activities. The beach is usually less sheltered, and the light reflection at the sea level is particularly strong. If you are not used to wearing sunglasses, let the strong reflecting light directly to the eyes, causing light damage to keratitis, and the vision is relatively affected.
Pterygium e is not familiar with everyone, because the damage to the eyes is not as serious as the previous, but it has a direct related impact on life. The common cause is also the excessive exposure to ultraviolet rays, causing hyperplasia of the conjunctival tissues of the eyes, which not only easily causes the cornea to dry and thin, which can lead to infection or inflammation. In severe cases, resulting in astigmatis, blurring vision and affecting imaging.
How to prevent eye diseases?
-Wear UV400 Sunglasses: Choose UV lenses that can filter more than 95%. Should be noticed when buying, if you wear sunglasses that cannot really resist UV, the pupil will be enlarged and absorb more UV light. The damageof eyes can be double. In addition, it is recommended to choose gray and brown lenses. These two colors have the best eye protection effects, especially gray lenses. The great transmittance and balances all color systems. If you have color-coating lens of sunglasses, remember to turn to the back to confirm.
-Avoid wearing blue and pink lenses: most people will use 3C products every day, and blue lenses will let blue light enter the eyes, which will hurt the eyes, while pink lenses do not have any filtering effect, wearing is equal to not wearing.
-Wear a wide-brimmed hat or parasol: if the UV index is greater than 6, in addition to wearing sunglasses to protect, you can also add a wide-brimmed hat or parasol to assist, the front edge of the hat must be long enough to cover the strong Light, add an extra layer of protection.
It's never too late to protect your eyes. Get in the habit of carrying sunglasses early. In the future, you can use your eyes to appreciate more beautiful and interesting things and maintain a certain quality of life.
