Final answer:
It is true that contact lenses can be worn during visual acuity tests. They correct vision directly on the cornea, offering a true representation of an individual's corrected vision during an exam.
Step-by-step explanation:
True, contact lenses can indeed be worn while testing visual acuity. Contact lenses are designed to sit on the eye's cornea, correcting the visual impairment directly at the point of light entry into the eye. They are often used not only for cosmetic reasons but for their practical advantages over glasses.
Contacts provide consistent vision correction regardless of eye movement, offer improved peripheral vision, and can even correct some corneal astigmatism.
Therefore, they contribute to a more accurate assessment of visual acuity during an eye examination.
When a person is tested for visual acuity, using a Snellen chart or any other method, wearing contact lenses that are properly fitted and prescribed by an eye care professional is appropriate as long as they accurately represent the individual's corrected vision.
