Examinations for visual sharpness, or acuity, often involve the use of a Snellen chart for evaluating distance vision, and near-vision test cards to gauge one’s ability to see objects up close.<\/p>\n
\n
Refraction exams evaluate how well the eye focuses light directly onto the retina through the cornea and lens. These tests are helpful in identifying conditions like longsightedness (hypermetropia), shortsightedness (myopia), and abnormal eye curvature (astigmatism). By studying how light reflects off the eye when using various lenses, optometrists can objectively determine the prescription needed for glasses or contact lenses to correct the vision issue. Subsequent visual acuity tests confirm that the newly prescribed lenses allow the patient to see clearly, with minor adjustments made as necessary.<\/p>\n
\n
Visual field tests may be conducted to evaluate eye conditions like glaucoma, which involves elevated fluid pressure in the eyeball, or neurological issues such as a stroke.<\/p>\n
