How to properly care for contact lenses in winter.
In winter, the temperature difference between indoors and outdoors is large and dry, so you need to pay special attention to the health of your eyes, which is sensitive to changes in the external environment.Especially, if you wear contact lenses, you need to be more cautious. Because you can. Due to the temperature difference indoors and outdoors, eye fatigue increases, which directly affects eyesight, so if you neglect hygiene management, you may suffer from various inflammations.
- Prohibited to wear for a long time
In winter, when the temperature is low and cold wind blows, the eyeballs tend to lack moisture. Wearing contact lenses for a long time in a dry environment makes your eyes more tired. This is because the lens interferes with the normal formation of the tear film and suppresses the supply of oxygen, causing dry eyes and redness.
When the eyes are dry, the corneal surface becomes rough, causing the eyeball to rub against the eyelids or surrounding dust, which can cause microscopic scars, which can lead to loss of vision. In particular, if you rub your stiff eyes with a feeling of foreign body strongly with your hands, you should be careful as corneal clouding or corneal loss may occur. Instead, blink your eyes often or close your eyes for a while and take a break. Inserting artificial tears that do not contain preservatives in the gap will help relieve symptoms.
- Correct lens wearing time
To avoid the side effects of wearing contact lenses, you need to know how to wear them properly. The best way is to wear glasses rather than lenses. If you wear lenses, it is appropriate to wear them for 4-6 hours a day, and avoid more than 8 hours. Occasionally, you can wear them all day or fall asleep with them because they are not very uncomfortable. This is a very dangerous behavior. This is because there is a risk of corneal edema due to lack of oxygen in the eyes during sleep.
- Hygienic lens management is required
In addition to the time to wear the lenses, the usual way to care for lenses is also important. When removing the lens, be sure to wash your hands with soap before removing, and immediately wash to prevent foreign substances from sticking to the lens. Also, use an exclusive cleaning solution and do not store it in a bathroom where a lot of germs are floating.
