If you have astigmatism, you will likely need to wear corrective glasses or contact lenses to help you see clearly. The length of time you will need to wear glasses or contact lenses to correct your astigmatism depends on a few factors, including the degree of astigmatism you have and the type of corrective lenses prescribed.
Glasses and contact lenses are used to correct astigmatism by refocusing light at different angles onto the cornea. This helps to reduce the distortion of vision that astigmatism causes. The degree of astigmatism you have will determine how much correction you need and the type of corrective lenses that will be prescribed. If you have a mild form of astigmatism, you may not need to wear glasses or contact lenses to correct it. However, if you have a more severe form of astigmatism, you may need to wear corrective lenses for a longer period of time in order to see clearly.
The type of corrective lenses prescribed will also affect how long you need to wear them. For example, if you have a high degree of astigmatism, you may need to wear hard lenses, which tend to be thicker and more durable than soft lenses. Hard lenses may need to be worn for a longer period of time in order to see clearly. On the other hand, if you have a mild form of astigmatism, you may be able to wear soft lenses, which are thinner and more comfortable to wear than hard lenses. Soft lenses typically need to be worn for a shorter period of time in order to correct astigmatism.
In general, you will need to wear corrective lenses to correct astigmatism for as long as it is necessary to achieve clear vision. Depending on the degree of astigmatism you have and the type of corrective lenses prescribed, you may need to wear glasses or contact lenses for a few months or up to several years. It is important to follow your doctor's instructions and wear the lenses as prescribed in order to get the best results.
