Yes, you will need glasses if you have a 0.25 astigmatism. Astigmatism is a condition in which the eye is unable to focus light evenly onto the retina, resulting in blurred vision. A value of 0.25 is considered to be a mild form of astigmatism, but it can still cause visual distortions, such as blurry vision at both near and far distances.
Glasses with lenses that have a specific prescription for your level of astigmatism can help to correct your vision and reduce or eliminate distortions. The lenses are specially designed to refocus the light entering your eye, so that it is correctly projected onto the retina.
In some cases, contact lenses may be used to correct astigmatism. However, depending on the severity of the astigmatism, glasses may be the better option. It is important to speak to an optometrist or ophthalmologist about your individual needs to determine which type of correction is right for you.
In conclusion, if you have a 0.25 astigmatism, it is likely that you will need glasses in order to improve your vision. Speak to an eye care professional to get the best advice for your individual situation.
