Confusion in eye power for making specs
When tested on machine my right eye power was old i. e; - 4 nd left eye power - 3.75 but when tested manually my right eye power was - 4.5 and left was same. Should I make new spectacle with machine power or manual power. Why there is difference

It's always better to use the power given after objective testing ie manual testing.

Computerized eye check up means objective refraction…which is usually done with help of an instrument names autorefractometer.
It will give a rough idea about power of glasses required by person.
This power given by computer ( autoref) is fine tuned by manual check up where in a person is exposed to different power glasses and glass power which gives best vision is advised by doctor as glasses prescription
So I would advise prescription calculated manually
