Yes, 180 astigmatism is considered to be a severe visual impairment. Astigmatism is a condition where the cornea, or the outer lens of the eye, is shaped irregularly. When the cornea is irregularly shaped, it causes a distorted or blurred image to be projected onto the retina, resulting in impaired vision.
When an individual has 180 astigmatism, this means that the irregularity of their cornea is severe. This can result in significant vision impairment, including difficulty seeing both near and far objects, double vision, and distorted vision. In addition, this level of astigmatism can lead to reduced contrast sensitivity, meaning objects may appear faded or less distinct than they actually are.
In order to manage 180 astigmatism, individuals may need to wear eyeglasses or contact lenses to help correct their vision. In some cases, laser eye surgery may be an option to correct the irregular shape of the cornea.
If left untreated, 180 astigmatism can lead to further vision impairment and a decrease in quality of life. Therefore, it is important to see an optometrist or ophthalmologist if you notice any changes in your vision. With proper diagnosis and treatment, the effects of 180 astigmatism can be corrected and your vision can be improved.
