Summer eye care
Start with UV protection
Summer is coming
Facing high UV weather
Sun protection is essential
But when it comes to summer sun protection
A lot of people only focus on the skin
And ignore the eyes
In fact
The eyes are an extremely delicate part of the human body
It's easier than skin
Damaged by ultraviolet rays
PART.1
Ultraviolet rays are harmful to the eyes
Ultraviolet (UV) radiation comes from the sun and is a type of light that is invisible to the naked eye, and is divided into three types: UVA, UVB, and UVC, with UVA and UVB being able to penetrate the Earth's atmosphere and cause effects on our skin and eyes. In summer, UV intensity peaks throughout the year as daylight hours increase and the ozone layer shifts, so it's important to protect your eyes from UV damage.
1. Increased risk of cataracts
Long-term exposure to strong ultraviolet rays can denature the proteins in the lens of the eye, leading to clouding and cataracts. It is a common blinding eye disease that severely affects vision.
2. Causes pterygium
Ultraviolet rays can stimulate abnormal tissue growth on the surface of the eye, resulting in pterygium, a pink, triangular growth of tissue that forms on the surface of the eyeball that can affect the appearance and, in severe cases, obscure vision.
3. Damage to the retina
UVB radiation can directly damage retinal cells, and long-term accumulation can increase the risk of macular degeneration, a disease that causes loss or even loss of central vision.
4. Dry eyes
Ultraviolet rays can also exacerbate eye surface dryness, reduce tear secretion, and trigger or worsen dry eye symptoms, such as dry and burning eyes.
PART.2
How to effectively protect it
1. Wear sunglasses
It is important to choose sunglasses that block 100% of UVA and UVB radiation. Note that the shade of color does not directly represent UV protection, the key is to check if there is a "UV400" or "100% UV Protection" logo.
2. Wear a wide-brimmed hat
Wearing a wide-brimmed hat can provide more shade to the face and eyes to some extent, reducing the amount of UV rays that hit the eyes directly.
3. Use a parasol
In places with strong reflections, such as beaches and swimming pools, the use of parasols can effectively reduce the UV reflectivity in the environment.
The summer sun is good
But it's just as important to take care of our eyes
through the above measures
We can effectively lower
Ultraviolet rays are harmful to the eyes
Enjoy a healthy and bright summer time
Prevention is always better than cure
Let's start now
Give the most gentle care to the eyes
