It is the gradual loss of the eyes ability to focus on nearby objects. The use of plus lenses to compensate for the reduction in the range of accommodation associated with presbyopia, brings the near point of accommodation to a comfortable distance for near visual task. This study is done to estimate an ideal clinical methods of measuring near addition for presbyopic patients. Material and Methods: Sixty healthy subjects with a mean age of 50 years were participatedin this study. Tentative near additions were determined usingnegative and positive relative accommodation (NRA __ampersandsignamp; PRA), fused cross-cylinder (JCC) and Near Duochrome. The power of the addition was then refined to arrive at the final addition. Result: There is no statistical significant difference between near duochrome and final addition power (0.03 __ampersandsignplusmn; 0.50) with p-value 0.584554 whereas there is statistical significant difference between NRA PRA (0.13 __ampersandsignplusmn; 0.55) with p-value 0.04105 and JCC (0.33 __ampersandsignplusmn; 0.46) with p-value __ampersandsignlt;0.00001 and final addition power. Conclusion: Average age of living in the world amongst humans are soaring day by day. The numbers of presbyopic people are also booming. Time as well as accuracy is a very important factor in current generation. Prescribing near addition is art for presbyopia which can be performed quickly and precisely by near duochrome test.&#13;
