Abstract
Aim: To measure the distance from the eye and the\ud refraction of the eye at the point at which print blurs\ud and the point at which it becomes unreadable.\ud \ud \ud Methods: Subjective accommodation in 7 early\ud presbyopic subjects (mean age 45 years), with no\ud additional near correction, was tested using 6/12\ud reduced Snellen and 6/12 Lea symbols. The point at\ud which blur was first noticed and the point at which\ud the print became indistinguishable were noted in\ud centimetres. Objective measures of refraction were\ud taken at each of these points.\ud \ud \ud Results: Subjective and objective results for reduced\ud Snellen and Lea symbols were simil...
