What conditions can soft contact lenses help correct?

Soft contact lenses are designed to correct a variety of refractive errors, which include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related difficulty in focusing on near objects). The materials used in soft lenses allow them to conform to the curvature of the cornea, providing a stable and comfortable fit that can effectively address these vision issues.

Myopia and hyperopia relate to how light focuses on the retina, with myopia resulting from the eye being too long and hyperopia from the eye being too short. Astigmatism occurs when the cornea is irregularly shaped, causing blurred vision, and presbyopia develops as the eyes lose the ability to focus on close objects due to age-related changes in the lens of the eye.

While soft contact lenses can also be designed to provide vision correction for certain forms of astigmatism and aid those experiencing presbyopia through multifocal lenses, the other options presented are limited in scope. For example, conjunctivitis is primarily an eye condition involving inflammation and infection and does not require lenses for correction. Color blindness is typically managed through visual aids rather than correction by lenses, while issues with night vision are associated with the function
