Beware! It is not suitable to wear contact lenses in these situations!

Big deal!!! The following situations are not suitable for wearing contact lenses !

When you have a cold

During a cold or illness, a person's resistance is weakened and the ocular surface is in a fragile state. Wearing contact lenses at this time will irritate the eyes and may cause eye inflammation such as keratitis and conjunctivitis. It is recommended to wear frame glasses instead.

In addition, most cold medicines contain many tear-inhibiting ingredients. Reduced tear secretion can make contact lenses too dry, which in turn affects vision. During a cold, the tear secretion of the eyes decreases, and bacterial metabolites are deposited near the lens, which reduces the oxygen permeability of the contact lens and subsequently causes eye infection.

Sleeping

Wearing contact lenses while sleeping will cause the cornea to be in a state of hypoxia for a long time, which can easily cause corneal damage and increase the incidence of keratitis.

When swimming

Contact lenses have adsorption properties, and pathogenic microorganisms in the water can easily deposit on the lenses when swimming, increasing the risk of corneal infection.

Eye inflammation or discomfort

When suffering from eye inflammation such as entropion, sty, dacryocystitis, insufficient tear secretion, dry eyes, conjunctivitis, trachoma, keratitis, etc., the eyes are very sensitive. Wearing contact lenses at this time can easily induce intraocular infection, eye pain, decreased vision and other symptoms.

When riding for a long time

When riding a bicycle for a long time, the speed of surrounding air convection will obviously increase, causing the moisture contained in the contact lenses to decrease sharply, and the lenses will gradually dry and harden. Over time, the hardened lenses are very likely to damage the corneal epithelial tissue, causing eye pain, itching, redness, swelling and even inflammation.

At the same time, dust and other foreign objects are more likely to enter the eyes when riding a bicycle, causing eye discomfort or even infection.

When traveling by car or plane for a long time

When riding on high-speed trains or trains for a long time, in a confined space, it is impossible to take good care of your contact lenses, and you cannot put them on and off in time, which increases the chance of corneal infection.

It is also best not to wear contact lenses when flying for a long time. Because after the plane climbs to a high altitude and flies level, the low air pressure in the cabin causes a drop in oxygen partial pressure, which aggravates dry eyes and discomfort. In addition, wearing contact lenses will increase the possibility of infection. It is recommended to wear frame glasses when flying.

Female menstrual period

During menstruation, women's intraocular pressure is higher than usual, and the area around the eyeball is more prone to congestion, making it unsuitable for them to wear contact lenses.

pregnancy

Because women's endocrine system changes during pregnancy, the biomechanics of corneal tissue will become softer. Wearing contact lenses blocks the contact between the cornea and the air, causing corneal hypoxia and making acute corneal damage more likely to occur.
