Is it safe to wear protective glasses in misty days?

The continuous haze and grey days have also discounted everyone's good mood. The incidence of respiratory-related diseases, such as cough and cold, and upper respiratory tract infection, has risen significantly. Everyone has taken up masks to reduce this bad air. The impact of coming.

In fact, the continuous existence of haze not only damages the respiratory tract of the human body, but also makes human “window of the soul” become “glass of frost” or even “broken glass”. Recent eye clinics have seen many patients with red eyes and itching as the main symptoms.

The human eye is in close contact with the air every day just like our skin. To reduce the damage caused by polluting the air, we can use a mask to cover our nose and mouth, but our eyes cannot cover it with a mask. Although wearing protective glasses is an effective method, wearing protective glasses will bring various inconveniences to our lives. At the same time, protective glasses are prone to fogging and other reasons.

In fact, the eyes are inseparable from the air, the cornea, which is the transparent film on the black eyeball, and its oxygen supply is 80% from the air. The surface of the eyeball, in order to maintain the optical effects of the cornea, has a thin film of water on the surface called a tear film. Do not underestimate this thin layer of tear film, without it, we see things will become blurred, the eyes of fatigue, dryness, etc. will be very obvious, watching TV can not continue for a long time.

The water film also has the ability to adhere to fine particles. When the density of fine particles of dust in the surrounding air increases, they will not only be inhaled into the respiratory tract, they will be dangerous to health, they will also adhere to the surface of the tear film, and they will be difficult to separate once they are attached. If these tiny dust particles carry many pathogenic microorganisms and even chemical components such as acid and alkaline stimulants, it will directly lead to damage to the ocular surface tissues. We will also feel itchy eyes, eye pain, eye acid and other discomfort. This is why the number of patients with haze eye disease increases significantly.

For patients who use contact lenses, also known as contact lenses, it is more likely to have eye diseases such as red eye pain in this hazy weather. Because wearing a contact lens is equivalent to adding a layer of diaphragm between the cornea and the air of the eye, which will reduce the amount of oxygen obtained from the cornea. Relatively speaking, the wearer’s eye surface has less resistance to adverse stimuli. In addition, the hydrophilic materials used in current contact lenses have a strong adsorption capacity, and harmful particles adhered to them may enter the contact lens material and endanger the patient's eye health for a long time.

From the medical point of view, it is recommended that people minimize the time to go out in hazy weather, go home or enter the room and use eye drops such as artificial tears to wash out smear particles attached to the surface of the eye to reduce their irritation and pathogenic effects. For those who use contact lenses, it is recommended to use care droplets that can be used when wearing glasses. The purpose is also to reduce smear particles that adhere to the surface.
