Not Everyone is Suitable to Wear Contact Lenses
Contact lenses, from the myopic patients’ point of view, are playing very important roles in their daily life. They have several advantages which cannot be ignored, such as convenience and beauty. However, it needs to be noteworthy that not all people are suitable to wear contact lenses.
On one hand, patients have to go through professional examination by physicians before choosing glasses, in order to see whether their own eye condition is fit to wear contact lenses or not. On the other hand, their work environment, age, etc. also need to be taken into consideration, specifically from the following notes:
1. Contact lenses are not suitable for people who have serious eye diseases, such as eyelids, conjunctiva, cornea inflammation, trachoma, dacryocystitis, lacrimal duct blockage or a reduction of tear secretion; monocular vision and nystagmus.
2. Systemic diseases: people who are sensitive to any discomfort and have a nervous disposition, especially those with serious sensitive eye pain are not recommended to select contact lenses, nor are people with decreasing systemic resistance, such as diabetes, pregnancy; arthritis and sinusitis.
3. Environmental conditions: when patients are under sand, dust and volatile acid-base environments, they must not wear contact lenses
4. Personal qualities: those who have poor hygiene are not fit for contact lenses, either; otherwise, it will bring great harm to their health.
5. If one has just finished the surgery of vision correction within 1 year, then ordinary eyeglasses rather than contact lenses are suggested to put on.
6. Contact lenses are not suitable for primary and secondary school students, for they are still in a vigorous period of growth and development, and the eye visual axis has not been fully developed. If they prematurely or in a long term, put on contact lenses, it is prone to bring about corneal hypoxia and physical side effects, such as metabolic disorder. Meanwhile, if the curved path of lenses is incompatible with the cornea, it will not only result in corneal abrasion, but also cause corneal ulceration or perforation as a consequence.
7. After the age of 40, people should gradually say goodbye to contact lenses as well, because eye tissues, at this time, are more likely to generate obvious degenerative changes and cause eye resistance to decline, especially the reduction of eye’s ability to withstand hypoxia. Therefore, people within 40 years old to 60 can sometimes wear contact lenses for a short term, but for those over 60, it is best not to put on them anymore.
All in all, in spite of their convenience and beauty, whether to choose contact lenses still depends on many factors, such as age, environment and personal quality, etc. Thus, not everyone is fit for wearing contact lenses. In some cases, ordinary eyeglasses will be quite a good option. As long as people pick out the right suitable ones for themselves, they can also achieve the same effects as contact lenses do.
