NCLE VERTEX DISTANCE

[@Hyena87]

Hey, Sam! I just passed my NCLE! I wanted to thank you for these videos and the work you do here! I probably couldn't have done it on the first try without you!

[@nclecontactlenstraining]

Congrats. I love hearing that! Go celebrate - that’s an awesome accomplishment 🎉 🎊

[@loisgoeswalking8063]

Yes I would greatly appreciate a video going over the mathematical equations as well!

[@gabytrosie]

Thank you for explaining this so simply I can finally understand it. Please consider doing videos for the ABO exam, I have coworkers training for it and they are having difficulty with it.

[@nclecontactlenstraining]

Thank you for your encouraging words! I wouldn’t be surprised if I ended up diversifying into more ABO-type content!

[@otiebrown9999]

This is excellent. This knowledge will help me get out of myopia!

This video really helped me to understand why Vertex distance is compensated !! I would like to learn a formula as well though.

[@nclecontactlenstraining]

Hey! Thanks for watching. I have other vertex distance videos covering the formula 😀

[@savannahstandefer6693]

I know thus video is old and I’m kind of late but this was very useful. I’m studying for my NCLE , scheduled to take it dec 19th. What I need help understanding is applying vertexing for powers less than the rule of them 10.00D.

[@nclecontactlenstraining]

Hi Savannah! Thank you so much for watching. Please keep us posted after you dominate the NCLE! For vertex distance just remember that when going from a refraction or “eyeglass Rx” to a contact lens Rx the prescription always becomes more plus or “less minus.” *starting at 4 diopters

I'm in Opticianry school studying for my NCLE; we were taught CAP/FAM; CAP closer add plus/FAM father add minus; we use D squared/1000 x distance moved in mm so: -10.00 SPH refracted at 12 mm would be 10 x 10 = 100/1000 = .10 x 12 = 1.2 CAP closer add plus -10.00 + 1.2 = -8.8 or 8.87 SPH for contact lens

Hi, Brian. I have never heard of that acronym for VD before. That’s a great mnemonic device. Thanks for sharing 😃 Enjoy your opticianry program and go get that NCLE 👊🏼

[@amarachichukwukere9699]

It was really helpful. Thank you.

[@nclecontactlenstraining]

Awesome. So glad to hear!

[@BayAreaEventDesigns]

Could you go over some of the common math problems on the ncle? Thank you for all your videos they are very helpful.

[@nclecontactlenstraining]

I am planning on adding content on a regular basis, as I find the time. I will be sure to add some videos that cover some of the equations you may encounter on your NCLE. Thank you for watching!

[@cindykrogg3999]

Thanks you made understanding that very easy not complicating it

[@nclecontactlenstraining]

Glad it was helpful 😃

[@TheLeeanngonzalez]

your a great teacher! thanks!

[@nclecontactlenstraining]

Thank you so much. I enjoy it!

Hello and Thank you for the great Video's. I am studying for the NCLE and the questions are Patients spec's rx is -12.00 +0.50 x 90, sit 10 mm in front of cornea for a soft contact lens rx how to figure the vertex distance. #2 +8.50 sit 12 mm power of soft contact lenses vertexed? can you provide an easy steps. thank you victoria

[@dhotstuffg]

In the first half of the video you say that it’s more plus when the lens gets closer to the eye but at the end you say it’s more negative when you get closer ... I’m confused which part is correct

[@nclecontactlenstraining]

Hi! The farther away a lens is from the eye, the more positive (+) it will behave. That is why contact lens prescriptions, over 4 diopters, are prescribed with more (+) power. We want the contact lenses to behave as the same strength as the phoropter during the examination - even though they are sitting in situ, on the eye. Basically, contact lens Rx’s are more plus (less minus) then the eyeglass refraction.
