You with glasses
Have you ever encountered these embarrassments and troubles in winter?
(Source: self-drawn)
Nineteen twenty-nine does not shoot, three-nine-nine-nine ice walks
Count nine cold days, the hot-blooded youth who are facing the wind and peeing three times
It has become much more low-key and introverted
But it accidentally intensified the contradiction between glasses and water vapor

Cultural people with glasses
The struggle with water vapor is unspeakably painful
The light can't see the road, and the heavy hits the tree
Today, Dr. Tao Yong and his little eyeball friends
Take you to a winter eye protection battle
Facilitate your travel and teach you to protect your eyes
(If you don't wear glasses, you can go straight to the second part.)
Begin!
1. Source Blocking Method – "Transform" your mask
Applicable:
Empty outdoors with few people
Replace the new mask in time after entering the room
Retrofit Method:
Prepare a tissue and fold it in half
Just stick a tissue inside the mask
Poke the video and learn it
The gas we exhale is blocked by masks
Change the direction of flow
Follow the gap in the nose clip of the mask upwards
Paper towels absorb exhaled water vapor
The glasses don't fog
Scratch the point!
(Listen to Tao Xiaotao!) Source: self-drawn)
2. Terminal solution - coating your glasses
Squeeze some neutral detergent on the glasses
Spread evenly and rinse off with water
Then gently wipe off the remaining water with a spectacle cloth
Detergents form a protective film on the surface of the lens
Among them the surfactants
Prevents condensation of water vapor into water droplets[1-2]
However, the effectiveness of homemade anti-fogging agents is limited and is only suitable for emergency needs
If you want better, longer-lasting anti-fog results
To choose anti-fog spray, mirror cloth, lenses and other special equipment
Remember!
Detergents must be neutral
Do not use soap, laundry detergent and other acids, alkaline is too strong
or granule-containing detergents such as toothpaste
so as not to damage the lenses
Common neutral detergents are:
"Do not hurt hands" dish soap, laundry detergent,
Baby toiletries, silk wool products cleaner, etc
Take a look at the ingredient list
The pH value is between 6 and 8
Have you learned these 2 methods?

Winter brings all kinds of dressing fashion back to basics
When you go out, you have to wrap yourself up and show only your eyes
As the only part where you can't "get dressed"
Are our eyes afraid of cold? Will they catch a cold?
How to protect big eyes in winter?
Let's start with the answer to the first question:
Are our eyes "afraid of cold"?
unafraid!
The eyes are protected by a "barrier" eyelid (eyelid).
There is also a "heating" of the room water that continues to circulate, bringing heat
Even at low temperatures, it can be kept at a constant temperature
In addition, there are no nerves in the eyes that feel cold and warm
Very sluggish in feeling the temperature
They are not "afraid of the cold" because they do not feel it[3]
(The small eyeball beats the nose, ears, and eyes.) Source: self-drawn)
But
Although they are "not afraid of the cold", they will also be "frostbitten"
Winters are cold and dry, with frequent symptoms such as dry eyes and tingling
If immunity is reduced, allergic conjunctivitis can easily be induced[4]
In winter, your eyes need more protection
A healthy and eye-protecting guide to help you kill two birds with one stone
1. Spa hot bath
Take a hot spring and take a hot bath
It can promote blood circulation and accelerate metabolism
Our eyes also like warmth
Warm compresses to the eyes can help the meibomian glands expel secreted oils
Promotes the secretion of tear fluid
Improves symptoms of eye strain and dry eye[5]
Let you have a pair of watery eyes in winter
2. Avoid hot and cold
Winter indoor and outdoor temperature difference large
Hot and cold situations can easily cause fluctuations in intraocular pressure
May induce acute glaucoma [6-7]
Go outside or after sweating for exercise
You can wait a while in the "temperature transition zone"
(Such as the door of the home, the door of the mall, etc.)
Adapt your body to the ambient temperature in advance
3. Strengthen exercise
Exercising consistently in winter can help improve blood circulation
Boosts autoimmunity and defends against various diseases
The little eyeballs have to move too
Especially the miserable workers and the people who love to play games
Keep your eyes open for a long time, staring at the electronic screen without moving
It is easy to strain the eye muscles and become convex and stiff in the lens
Causes spasm of the ciliary muscles, causing or exacerbating myopia[8]
Try the "20-20-20" eye protection rule:
Use your eyes for 20 minutes each time
Look at objects 20 feet (6 meters) away
Relax for 20 seconds
It can free the ciliary muscle from the state of contraction and relieve fatigue and soreness
Prevents increased myopia induced by fatigue with the eyes[9]

4. Pay attention to hydration
Winters are drier, especially in the north
Heating makes the interior more dry and unbearable
Not only will the skin be tight, but it will also be prone to dry eye
Eyes should also be "hydrated" in time
Try yawning and blinking
The two movements seem simple, but they can effectively promote the secretion of tears
Eat more fruits and vegetables rich in vitamins A and C
Such as carrots, apples, bananas, cherries and so on
Good for the eyes [10-11]
"20-20-20" eye protection rule
It is also effective for relieving dry eyes
Dr. Tao Yong teaches you the winter eye care battle
Have you learned all?
Don't forget to forward to the circle of friends and click to watch
Let's spend the New Year in peace and security together
