Probably the most important part of the low vision examination is the:

• A. Refraction
• B. Visual field testing
• C. Color vision
• D. Fundus exam

Answer: (A)

Maximizing a patient’s remaining vision starts with accurate refractive correction. A thorough refraction identifies how much lens power can improve central vision and establishes the best possible acuity the eye can achieve with lenses. This corrected acuity serves as the essential baseline for deciding on optical aids, magnification needs, and overall functional goals in a low vision exam. Once the best correction is set, clinicians then evaluate how lighting, contrast, and assistive devices further enhance vision. Other elements like visual field testing, color vision, or a fundus exam provide valuable information about eye health and function, but they do not directly raise the patient’s central acuity the way a precise refraction does.
