1. Refractive Errors

The most common cause of blurred vision is refractive errors.²Blurred Vision By Christopher J. Brady, et al. ‘Blurred Vision - Eye Disorders.’ Merck Manuals Professional Edition, Merck Manuals, www.merckmanuals.com/professional/eye-disorders/symptoms-of-ophthalmologic-disorders/blurred-vision. A refractive error occurs when the eye fails to bend light properly, interfering with proper focusing and causing a blurred image.⁴‘Nearsightedness: What Is Myopia?’ American Academy of Ophthalmology, 22 Dec. 2020, www.aao.org/eye-health/diseases/myopia-nearsightedness.

Myopia, or nearsightedness, causes blurred vision when viewing distant objects, while farsightedness, or hyperopia, causes blurred vision when viewing objects up close. Presbyopia is an age-related condition that results in impaired close-up vision. Astigmatism, caused by distortion in the eye’s lens, may result in blurred vision at any distance. Refractive errors can be corrected with prescription eyeglasses, contact lenses or surgery.⁵‘Common Eye Disorders and Diseases.’ Centers for Disease Control and Prevention, Centers for Disease Control and Prevention, 3 June 2020, www.cdc.gov/visionhealth/basics/ced/index.html.
