The importance of eye sun protection
Summer is here, and sun protection is essential in the face of high ultraviolet weather. However, when it comes to summer sun protection, many people only focus on the skin and ignore the eyes. In fact, the eyes, as an extremely delicate part of the human body, are more susceptible to ultraviolet damage than the skin. Long-term exposure to ultraviolet rays increases the risk of eye diseases such as cataracts and macular degeneration. In addition, ultraviolet rays accelerate the aging of the skin around the eyes, leading to problems such as wrinkles and dark circles. Wearing sunscreen glasses can reduce the risk of such skin aging. At the same time, in a strong sunlight environment, the eyes need to constantly adapt to changes in light, which can easily lead to eye fatigue and discomfort. Wearing sunglasses can alleviate this discomfort.
Ultraviolet damage to the eyes
Ultraviolet (UV) radiation comes from the sun and is a type of light that is invisible to the naked eye. It is divided into three types: UVA, UVB and UVC. Among them, UVA and UVB can penetrate the earth’s atmosphere and affect our skin and eyes. In summer, with the increase in sunshine time and seasonal changes in the ozone layer, the intensity of ultraviolet rays reaches its peak in the year. Therefore, it is particularly important to protect the eyes from ultraviolet damage.
1. Increase the risk of cataracts
Long-term exposure to strong ultraviolet light may cause protein in the lens of the eye to denature, leading to turbidity and cataracts. This is a common blinding eye disease that seriously affects vision.
2. Cause pterygium
Ultraviolet light can stimulate abnormal growth of tissue on the surface of the eye, forming pterygium, a pink, triangular tissue hyperplasia formed on the surface of the eyeball, which affects the appearance and may block vision in severe cases.
3. Damage to the retina
UVB radiation can directly damage retinal cells, and long-term accumulation may increase the risk of macular degeneration, a disease that causes decreased or even loss of central vision.
4. Dry eye syndrome
Ultraviolet light can also aggravate dryness of the ocular surface, reduce tear secretion, and cause or aggravate dry eye symptoms, such as dry eyes and burning sensation.
What are the sun protection measures?
1. Wear sunglasses
It is crucial to choose sunglasses that can block 100% UVA and UVB radiation. Note that the depth of color does not directly represent the ability to block ultraviolet light. The key is to check whether there is a “UV400″ or “100% UV Protection” logo.
2. Wear a wide-brimmed hat
Wearing a wide-brimmed hat can provide more shade for the face and eyes to a certain extent, reducing the amount of UV rays directly hitting the eyes.
3. Use a parasol
In places with strong reflections such as beaches and swimming pools, using a parasol can effectively reduce the UV reflectivity in the environment.
Although the summer sun is good, it is equally important to protect our eyes. Through the above measures, we can effectively reduce the damage of UV rays to the eyes and enjoy a healthy and bright summer time.
