Although nowadays taking planes has been more and more comfortable, the humidity, barometric pressure, changes of gravity and so on inside the cabin still can affect the healthy condition of the passengers including the eye conditions. First of all, the air inside the cabin is usually very dry and barometric pressure there can often lose balance, which will affect your eyes and lead to discomfort. If you are wearing the eye contacts, you may feel uncomfortable eyes. In addition, the dry air inside the cabin will make the water on the surface of the eyeballs evaporate at a high speed, which makes the eye contact lenses become very hard and dry very soon, thus easily making the proteins in the tears that the eyeballs secrete dry and hard and insufficiency of oxygen in the cornea. Therefore, you had better not wear eye contacts when you are taking planes. Besides, if you wear eye contacts, you may have to take care lenses for your contacts lenses and you have to apply for consignment for it, which also makes it inconvenient. So it is better to prepare a pair of frame eyeglasses which is convenient to take and wear.
