what level of astigmatism require glasses

The level of astigmatism that requires glasses depends on the individuals vision and degree of astigmatism. However, most sources suggest that glasses are needed if astigmatism has a strength of 1.0 or more. According to Advanced Family Eye Care, between .75 and 2 diopters is considered mild astigmatism and can be easily corrected with eyeglasses. Healthline suggests that glasses are needed for astigmatism if vision is blurry or distorted, and if the person experiences double vision, trouble seeing at night, headaches due to eyestrain, or frequent squinting. It is important to note that not everyone with astigmatism will need glasses, and it is possible to have slight astigmatism and still have 20/20 vision. Regular eye checkups are important to monitor changes in vision over time, and corrective surgery or orthokeratology can be used to correct vision instead of glasses in some cases. Ultimately, it is best to consult with a qualified eye doctor to determine the level of astigmatism and whether glasses are needed.
