Yes, 100 astigmatism is considered severe. Astigmatism is a type of refractive error that occurs when the cornea is irregularly shaped or when the eye’s natural lens is not symmetrical. It is measured in diopters (D) and the higher the diopter number, the greater the amount of astigmatism present. A person with 100 astigmatism has a significantly distorted image, making it difficult to see clearly at any distance. This can cause blurred vision, eye strain, and headaches, as well as double vision and difficulty in seeing in dim light.
Those with 100 astigmatism may require corrective lenses such as glasses or contact lenses to improve their vision. Treatment can also include laser eye surgery, which can reduce astigmatism by reshaping the cornea. However, it is important to note that this surgery may not be suitable for everyone and should be discussed with an ophthalmologist.
In conclusion, 100 astigmatism is considered severe and can cause a range of vision issues. It is important to seek the advice of an eye care professional to determine the best treatment for your individual needs.
