When it comes to the precautions for expectant mothers during pregnancy, they should either quit smoking and alcohol, cultivate good living habits, or stay away from drugs and pay attention to the living environment.
Few people seem to mention their eye health problems. Because most people think that pregnancy will never affect their eyes. No, no, there's one thing that can't be underestimated for pregnant mothers. It's contact lenses.
Many expectant mothers who wear contact lenses will find that during pregnancy, the contact lenses they have been wearing suddenly become very uncomfortable.
Why is this? There are two main reasons ☟ ☟
❶ after pregnancy, the physiology of expectant mothers changes, and the secretion of tears is greatly reduced, resulting in the symptoms of foreign body sensation, dry eyes, astringent eyes, and even congestion and redness when wearing contact lenses.
❷ the moisture content of the cornea of the mother to be will continue to increase, especially at the end of pregnancy, the permeability of the cornea will become poor, and the intraocular pressure will drop, which will narrow the vision of the mother to be and aggravate the discomfort of wearing contact lenses.
Therefore: during pregnancy, the slight edema of corneal tissue, the increase of corneal thickness, and the deterioration of permeability will all lead to corneal hypoxia. At this time, wearing contact lenses will increase the degree of corneal hypoxia and reduce corneal sensitivity, so that expectant mothers are prone to symptoms such as decreased vision and unexplained tears.
Moreover, during pregnancy, the corneal arterioles of expectant mothers will contract and the blood flow will be reduced. If wearing contact lenses at this time, it will not only make the cornea lack of oxygen, but also easily cause conjunctivitis.
It is worth noting that wearing contact lenses during pregnancy is not only bad for the mother, but also harmful to the fetus
❶ the contact lens care solution necessary for wearing contact lenses may affect the fetus after long-term use because it contains certain pharmaceutical ingredients.
❷ many eye drops and ointment contain ingredients harmful to the fetus.
So expectant mothers had better not use these products. If they must use them, they must consult a specialist.
If some expectant mothers just need glasses when reading or looking at very small things, they can try not to wear glasses at ordinary times. If you are a mother to be with high myopia, it is recommended to choose frame glasses.
In addition, myopic expectant mothers need to be careful not to choose to have vision correction surgery during pregnancy.
First, at this time, the hormone level in the mother to be is very different from that at ordinary times, which can not guarantee a good treatment effect.
Second, the immunity of pregnant women will decline and the probability of infection will increase.
Third, vision correction surgery requires the use of antibiotics and hormone drugs, which may affect the fetus through the placenta. So, wear frame glasses honestly.
