How to match contact lenses with astigmatism?
The process of formulating astigmatism contact lenses is basically the same as that of ordinary contact lenses, but it needs to be checked by a professional eye hospital and customized with the help of a doctor. Today, we will briefly introduce how to match contact lenses with astigmatism.
Whether you can wear contact lenses depends on your eye conditions, so you must first have an optometry examination. A detailed eye examination can help us distinguish nearsighted astigmatism, farsighted astigmatism, and know the axis and specific degree of astigmatism. If conjunctivitis, dry eye, keratitis, cataract, glaucoma and other diseases are found during the examination, it means that astigmatic contact lenses are not suitable for wearing.
If astigmatism does not affect normal vision, you can consider matching a pair of ordinary contact lenses according to the degree of myopia or hyperopia. However, if the degree of astigmatism has exceeded 75 degrees or has a great impact on vision, then you need to customize a pair of astigmatism contact lenses specially designed to correct astigmatism.
After the astigmatic contact lenses are customized, they can be tried on under the guidance of a doctor. Generally, in order to reduce eye fatigue and obtain a better correction effect, the actual degree of preparation may be a little lower than the measured degree, so it is necessary to try on to feel whether the correction effect and comfort meet the requirements.
In order to ensure the axial position of astigmatic contact lenses, the lenses are thinner at the top and thicker at the bottom, so they are more fragile than ordinary lenses. When nursing, you need to pay special attention. You must be gentle when rubbing, and you can't use too much force during the process of taking it.
After starting to wear astigmatism contact lenses, it is best to go to the hospital to review the eye condition regularly. In addition, in daily life, you should also pay attention to adjusting your daily routine, participating in more outdoor sports, and paying attention to eye care.
