Refraction

Refraction, to determine the lens correction needed to provide optimal visual acuity for all viewing distances.? The refractive analysis may include:

• Measurement of the patient's most recent optical correction
• Measurement of the anterior corneal curvature (the shape of the front surface of the eye)
• Objective measurement of refractive status
• Subjective measurement of monocular and binocular refractive status at distance and near
