Astigmatism is a common vision condition that can make it difficult to focus on nearby or far away objects. Astigmatism is caused by an irregularly-shaped cornea, which is the clear, dome-shaped front surface of the eye. It can be corrected with eyeglasses, contact lenses, or refractive surgery. However, these treatments do not always work at night, as the eye's shape can change due to a variety of factors, such as tiredness or changes in the environment.
Corrective Lenses
Eyeglasses and contact lenses are the most common treatments for astigmatism. They work by bending light rays as they enter the eye in order to correct the irregular shape of the cornea. However, these lenses may not be effective at night, as the eye's shape can change due to a variety of factors, such as tiredness or changes in the environment.
Eye Exercises
Eye exercises can help to strengthen the muscles in the eye, which can help to improve vision and reduce the symptoms of astigmatism. These exercises can be done at any time, including at night, and include activities such as rolling the eyes, focusing on objects at different distances, and tracing figures with the eyes.
Lifestyle Changes
Lifestyle changes such as getting enough sleep and avoiding eye strain can help to reduce the symptoms of astigmatism. Reducing the amount of time spent looking at screens can also help, as this can cause eye strain. Additionally, eating a healthy diet and avoiding smoking can help to improve overall eye health.
Prescription Eye Drops
Prescription eye drops can be used to relax the muscles in the eye in order to improve vision. These drops can be used at night, before bed or during the day, as needed. However, it is important to speak to an eye doctor before using these drops to ensure that they are safe and effective.
