Is it normal to have first-degree hyperopia without astigmatism?

Astigmatism can occur even without hyperopia. Astigmatism is a type of refractive error, referring to the condition in which parallel light rays form two focal points after being refracted by the eye's optical system. Types of astigmatism include: simple hyperopic astigmatism, mixed astigmatism, simple myopic astigmatism, and other astigmatic types. If a person has both astigmatism and hyperopia, corrective lenses should be prescribed based on actual conditions and examination results. In daily life, patients should maintain good eye-use habits, perform appropriate eye exercises, and consume more foods beneficial for eye health, so that astigmatism does not progress too rapidly.
