@Laramy-K Optical , Mr. Laramy-K. Please. Is it possible to set the correct prescription of a Prism, just with the total off-center distance (mm)? In my case I created a prism via optical center decentralization, the lenses were mounted at a distance smaller than my pupillary distance. 7mm each side towards the nose, totaling 14mm. Prentice would be: (-7.75 spherical myopia x 7mm)/10 = 5.425 Prism in each lens. Cylindrical Astigmatism -1.00 Presbyopia +2.00 To have the correct prism lens, would it be enough to add +5.4 Base Out ? I heard, that the correlation between Prisma Prentice would not be exactly 1:1, when prescribing a prism by normal methods. I'm a layman on the subject, just a person who wears glasses.
@LaramyKOptical3 жыл бұрын
I just spent 20 minutes replying and then KZbin dropped me... grrrrrr. If cylinder is present then you would need to determine the power at 0-180 using the power in oblique meridian formula. Your D would probably change a little. The add or presbyopia correction shouldn't matter in this. I'm assuming these are single vision or a lined style bifocal? You can't move a progressive lens to create prism. Many things come to mind here: Prism is about the brain and perception so it is correct that there is no 1:1 correlation between power, position and what an individual will perceive. Which is why it is best done in front of a phoropter or with using trial lenses. Experimenting may end up being costly and time consuming - sorry. If you are trying to self troubleshoot and order glasses online then you could order them with the PD you figured out you NEED, not your actual PD. Again assuming these are single vision that would be an inexpensive way to find out if you have things sorted. I hope this helps a little. Not an easy thing to sort out.

@Laramy-K Optical Thanks John. My glasses has PROGRESSIVE LENSES (Hoyalux VXT Premium, 1.67), not listed in hoyavision site, only in Brazilian site. Due to decentration, if I see with 1 eye, I must rotate litte bitte my head (up to 5°), to have perfect vision ( aiming to the optical central vision area), in this 2nd glasses mounted with 54mm instead real Pupile Distance 68mm. With 59mm, my 1st glasses 3 years before, not necessary rotate my head. When I detected diplopia, the doctors did not indicate prisma lenses... I found my own solution and informed them, if I reduce the DP I do not have diplopia... Patient teaching the doctor... But if my diplopia increase, I think my method would not have effect and I will must to try a real Prisma lenses, however the doctors are not good (low knowledge) to define a correct Prisma lenses... and each error costs U$D 600 (lenses)

@LaramyKOptical3 жыл бұрын
@@setubosotubo Sorry but - if you are moving a progressive lens around and finding an area of perfect vision it is because either the lenses were made wrong or it is just some kind of weird luck. The optics of a progressive lens just simply DO NOT work that way. In fact the prism reference point on a progressive is about 8mm below where you are looking through the distance. Nothing you are doing or calculating is transferable to a progressive lens. Really sorry but it just isn't and I can't help you.

I am a customer not a student. I developed diplopia about 4 yrs ago. My ophthalmologist prescribed a prism prescription. My new prism glasses worked perfectly. One yr ago, I had a minor change in refraction -4.75 to -4.25 in one eye. I have had three tries by the same optical dispensary in my Dr's office. I accepted the last glasses but they really do not work as well as my original lenses that I wear now (diplopia not well corrected). I am 79 and have no diplopia reading; bifocal works well. My prescription: -4.75, +2.75, Prism 8 out on Rt lens, 1 up on R (cyl -.50 Left, Axis 097 L) We went with flat frame on last try; Is this a difficult lens prescription? If I have cataract surgery, my surgeon can correct with lens distance vision thus eliminating one variable in the prescription would this make the prescription easier to do correctly. I believe I need a new optician with three failures. Is there a process I could use to help find more qualified optician ?
@LaramyKOptical2 жыл бұрын
Just my opinion- I'm not a doctor. At 79 I would certainly give cataract surgery a try. You will eliminate a lot of power - hence a lot of what is giving you trouble. 8D prism is quite a lot. John

Smiling! I remember it, but I am 72 Gong Show, Chuck and Berry. One for you, Soupy Sales. Been having double vision issues the past year. Close ether eye and it's ok. Had RK done in 1990 and it worked good till about 5 years ago. Vision changes during the day now from + 200 reading glasses in the morning and few hours later prescription glasses. Not sure what my vision was before the RK but lets just say I couldn't see the big E on the chart. Went to my eye doctor today and looks like he going to put a prism of 1 out in both lenses to help with my vision. Hope it helps because I don't like closing one eye when driving pulling out in busy traffic. cylindrical +1.50 axis -2.25 prism 1 base out. cylindrical +3.25 axis -1.75 prism 1 base out.

Thank you for this video & explaining the basics of prisms.. I am a patient of 50 and for years I have had difficulty with eye exams and have never been satisfied with my finished glasses & that they were the correct RX. Finally I found an optician who discovered that I needed 2 dioptres of prism for reading & 1 for distance. I asked if this type of muscular disorder was often found in neuromuscular diseases of the body or restricted to the eye & he responded yes it was common in MS, Fibro, etc and I should report the finding to my PCP. My question is what exactly is the disorder called when your optic muscles do not move synchronized to make vision optional? Warm Regards,Gina PS.~ I am aware this is is going above & deyond but is much appreciated!

To solve my diplopia (double vision), when I have 2 eyes open: I disassembled the lenses from the metal frame, and brought them closer together until I found the distance between the optical centers of the lenses, where I had good vision (no double vision). Simulating prismatic base out lenses in both eyes. In my case myopia, astigmatism and presbyopia. The lenses were mounted at a shorter distance (Pupile Distance), so as not to have double vision. 54mm instead of 68mm. And the lenses need to have a wider visual field width. It seems that having a correct prismatic lens prescription is difficult. And this practical method was faster.

@Laramy-K Optical Dear John ! Your videos have full details and the best technical level in whole Internet ! Congratulations ! As engineer I am watching all videos to learn a little bitte. Please 1- Is easy the definition of a Prisma in progressive lenses to solve diplopia ( in my case Rx: spherical myopia -7.75 both eyes, cylindrical astigmatism -1.00 both, Right Eye: at 160°, Left Eye at 10° , addition presbyopia +2.00 both eyes) ? or Is it really very difficult to have sucess at first time/lenses and also depends on the doctor to have years of experience ? I observed that my right eye has a devition and would be the root cause, to diplopia.

I know this video is about prism but is there anyway you could explain to me how to figure out what base curve to use when you only have the prescription and the Box system to go by and also the patient's PD
@LaramyKOptical7 жыл бұрын
Chad, Base curve can be determined using Vogel's Rule, a base curve chart, or these days by letting the computer software decide or guide the best choice for a given Rx and material. I cover Vogel's and charts on the website. If you are neutralizing a pair of glasses (see this weeks video) then you should use a base curve clock and match the same one that is in the current pair of glasses. Remember that the lens clock is set for glass so if it is a surface job let the lab know what you got and how you got it so you don't end up with the wrong curve. Hope that helps! John

Hi Great video, one thing as a user of prism glasses that I have found is that no glasses dispenser seems to understand how thick a prism makes the lenses. I have a total of 11 Base in prism and the number of times I hear these are reading glasses we don't thin those. I always have to take on old pair of reading glasses with me when I order new readers to demonstrate just how thick the lenses are at the nose . So it would be great if you did a video showing the effect on the lens of adding Prism - Then I can just point people at your video
@LaramyKOptical Жыл бұрын
11D is quite a lot of prism. Any optician should know that would create thickness issues. If the optician doesn't know what prism is then how do they know if the job ws even done right? I'd find a better optical shop and stick with them.
