First time I have seen + Sign is in Red colour & - Sign in black 😂 But Your explanation was really exceptional & useful Sir Thank you & Keep continuing Sir for more videos 👌👌👌👍👍👍🤝🤝🤝🤝
Sir, I am studying B. Optometry, your video is Very nice and easily understood but have one doubt is how to measurement distance from patient eye to retinoscope?
Correct. Working distance is compensated with sphere only. Suppose if we get -1.00 DC only then after working distance compensation it will be -1.50 DS/-1.00 DC
First step is to find the type of movement then meridian of movement. Mostly we use sphere lens first to neutralize any one meridian. If it’s sphere all meridian will get neutralized with single sphere lens but if it’s astigmatism one meridian will get neutralized but other median will still show movement. At that meridian we have to use cylinder lenses to neutralize.
@@optometryreels then does it mean. Eg In your vid. 135 and 45 axis. So you put sph in 135 * and it neutralised in every axis. So does it mean pt in having sph only and no cyl?
