Can I wear contact lenses during my period?

Many people who are nearsighted but do not want to wear frame glasses choose to wear contact lenses. Of course, although wearing contact lenses can greatly improve your personal image, you cannot wear contact lenses at all times. For example, women cannot wear contact lenses during menstruation. In addition, pregnant women and people who need to look at computers for a long time are not suitable for wearing contact lenses!

1. It is not suitable to wear contact lenses during menstruation

Wearing contact lenses during menstruation can easily cause eye congestion. This is because, first of all, women's intraocular pressure is higher than usual during menstruation, and the area around the eyeball is more prone to congestion. This is especially true for women with dysmenorrhea. Wearing contact lenses at this time will have an adverse effect on the eyeball. Secondly, since the body's immunity decreases during menstruation, the local resistance of the eyes also decreases, and tear secretion decreases. Bacillus subtilis will multiply in large numbers, causing the bacterial metabolites to deposit between the cornea and the lens, resulting in reduced oxygen permeability of the contact lens. The normal metabolism of the cornea is disturbed, thus causing bacterial corneal ulcers.

2. The consequences of pregnant women wearing contact lenses are more serious

Statistics show that 30% of pregnant women will have eye problems when wearing contact lenses. If not treated in time, it will affect their normal life and may even increase the difficulty of treatment due to contraindications of medication during pregnancy. "When pregnant women wear contact lenses, corneal damage is the first to be affected, and it will also trigger a series of other diseases." Experts say that due to major changes in a woman's endocrine system during pregnancy, her corneal tissue will experience mild edema, which will increase the thickness of the cornea. Contact lenses themselves block the contact between the cornea and the air. Continuing to wear contact lenses during pregnancy will increase the degree of corneal hypoxia, reduce corneal sensitivity, and make acute corneal damage more likely to occur.

3. It is best not to wear contact lenses when using a computer

Many people who wear contact lenses will experience dry and astringent eyes and feel very uncomfortable if they look at the computer for a long time. This is because the number of blinks decreases. The contact lenses commonly used today are all made of polymer materials, which have poor oxygen permeability and, to a certain extent, hinder the eyes from directly breathing oxygen, causing corneal hypoxia. In addition, when facing the computer for a long time, the eyes are highly strained. A normal person blinks more than 20 times per minute, but if you wear contact lenses and face the computer for a long time, you will only blink four or five times per minute. In addition, poor hygiene habits during the use of contact lenses can cause keratitis and corneal ulcers, eye pain and photophobia, and in severe cases, it can cause blepharospasm, induce corneal neovascularization, and ultimately affect vision.
