True about retinoscopy with a plane mirror
Perform at 1 meter away Retinoscopy Differentiate b/w type of refractive errors Optical error & organic error Perform at 1 meter away Reflection of light with retinoscopy (plane mirror) 1. Against - myopia > -1 2. Witha. Myopia < -1 ( or)b. Emmetropia = 0 (or)c. Hypermetropia = + value 3. No Movements -Myopia = -1 With Concave mirror retinoscopy the movements are reversed
