Subjective Refraction Iii (Binocular Balancing)

This lecture describes the final steps in subjective refraction , which is the Binocular balancing and Binocular Addition . these steps are important to ensure equalization fusion and accommodative demand in both eyes .

Objective Refraction (Retinoscopy)

In this lecture you will be revised with the refraction components of the eye , types of refractive errors and the role of accommodation , further you will be introduced to the optical principles of the retinoscopy and how it works in order to determine the refractive errors
