What is the main purpose of contact lenses?

• A. To provide cosmetic enhancements
• B. To correct refractive errors and improve vision
• C. To protect eyes from foreign bodies
• D. To block UV light from the sun

Answer: (B)

The primary purpose of contact lenses is to correct refractive errors and improve vision. Refractive errors include conditions such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. Contact lenses are designed to bend light rays so that they properly focus on the retina, allowing individuals to achieve clear vision without the need for eyeglasses. While cosmetic enhancements, protection from foreign bodies, and UV light blocking are benefits associated with some types of contact lenses or other eyewear, they are secondary to the primary function of vision correction. The main intent behind prescribing contact lenses is to address issues related to vision impairment directly, making option B the most accurate representation of their fundamental purpose.
