In fact, many people with myopia have more or less symptoms of astigmatism. Because wearing frame glasses is inconvenient and affects appearance, more and more people with myopia choose to use contact lenses. However, there are rumors that people with myopia and astigmatism cannot wear contact lenses, which discourages many people who want to try and they can only continue to use frame glasses. So is there any scientific basis for this statement? Are people with astigmatism really not meant to wear contact lenses? What are the symptoms of “myopia + astigmatism”? Astigmatism is a relatively common eye disease, which is often combined with myopia and hyperopia. If not treated in time, vision will often deteriorate sharply. In life, if the following symptoms occur, you need to be alert to eye "astigmatism". Symptom 1: Blurred “Mengchacha” People with mild astigmatism usually have normal vision but may experience headaches, eyestrain, and blurred vision when looking at objects at a certain distance. People with severe astigmatism experience blurred and distorted vision. I can't see clearly whether far or near. I feel eye swelling and headache when working at close range for a long time. When reading, there are flickering lines or double images. Symptom 2: Visual fatigue Blurred images on the retina require constant fine-tuning, and vision is distorted, so patients with astigmatism, especially those with hyperopic astigmatism, are prone to visual fatigue. Symptom 3: Normal head and eye position: People with highly asymmetric astigmatism in both eyes often tilt their heads in order to see more clearly, which leads to strabismus. The astigmatism can be restored after correction. Can I wear contact lenses if I have astigmatism? There is not much difference between astigmatism and ordinary myopia. It is just that the light cannot be focused on one point, which can also be corrected using lenses. However, whether or not to wear contact lenses requires specific analysis. Astigmatism contact lenses need to be customized according to the different conditions of each person's eyes: 1. Regular astigmatism can be corrected using frame astigmatism glasses or astigmatism contact lenses. Irregular astigmatism can generally only be corrected with highly oxygen permeable hard contact lenses. 2. When corneal astigmatism is less than or equal to 1.75D and the spherical power: cylindrical power is greater than or equal to 4:1, there is no need to customize astigmatism contact lenses to correct astigmatism, but you can directly wear ordinary contact lenses. If your astigmatism is beyond 175 and the spherical power: cylindrical power is greater than or equal to 4:1, you should consider whether you can wear ordinary contact lenses. It is best to wear professional contact lenses specially equipped for people with astigmatism, which are the well-known astigmatism contact lenses. Friends with astigmatism can go to professional institutions and let professional ophthalmologists check it out. Are astigmatism contact lenses expensive? The price of astigmatism contact lenses is generally higher than that of ordinary contact lenses, and they are custom-made contact lenses. |
