its true progressive cant do everything perfectly. i am about to get my second progressive and this time from zeiss and my optician suggested smaller frames for index 1.67. what he told me was zeiss progression is much better and distortion wont be as much. i love my current glasses just that right eye may have increase powers. i adapted to my first almost immediately. my question is it true what my optician said that better brands of lens provide better comfort?
@LaramyKOptical4 күн бұрын
Without knowing much more all I'll say is, "there isn't any magic pixie dust." Zeiss makes some great lenses and you should do fine. As to "much better and distortion won't be as much." Maybe, maybe not, probably. I'm guessing your power is quite high - hence the 1.67 and the advice on using a small frame so it sounds like your optician may know what they are doing.
@guardian7keys4 күн бұрын
@@LaramyKOptical thank you kindly for your reply. 1.50-0.5 R 2.5 0.75 L still under 3.0 limit I suppose. He suggested 1.5 index if I insisted on a larger frame or if my power was higher than 3.0. his logic was to keep the overall weight of the spectacles light. Plus 1.67 index was much cheaper to consider over the 1.5 index sir

@@guardian7keys 1.5? CR-39 or Trivex? Sounds like maybe things are bit backwards? Unless you are talking about the dinner plate special sized frames weight differences will be negligible. Trivex is great. CR-39 is cheap but thick. 1.67 is OK for powers like yours but a tad of overkill.

@@LaramyKOptical I am not sure if the plastic is c39 or trivex sir. 1.67 was the thickest in the Zeiss light progressive 2 series. Its all really confusing 😭 I am really looking for an all rounder progressive. My optician has suggested a reading or computer pair. But asked to try the zeiss first if it fits for me day to day activities.
@LaramyKOptical3 күн бұрын
@@guardian7keys Even with the best progressive possible an additional pair of single vision for computer distance is a wonderful thing. The rest sounds like a misunderstanding - I'm not sure how they could possibly know how thick the lens might be when finished (unless they are surfacing and finishing it there) and 1.67 should be thinner than any 1.5 not thicker - that is the entire point of a higher index lens.

doesnt seem like its easy or straightforward to purchase a single pair of lenses from the website. but im interested in trying them. i sometimes get pain behind my eyes when im working and driving at night. i think my left eye gets it worse because im on the left driver side (USA) and i think the headlights of oncoming traffic hit my left eye a bit more intensely. its like a pressure behind my eyes, sometimes it hurts or causes a headache ;(

I would have to say, no. I doubt you can manually decenter for PD and then expect the edger to take care of an OC height. I guess it could work but you would have to experiment with the edger. The basics shown in the video assume no OC height = 1/2 the B. And OC heights are for higher powers and should be kept to around 0 - 5mm. If you need much more you have the wrong frame.

Hi - thank you for this refresher. As an Optom, I use resultant prism all the time. It's a shame that most DOs don't understand the notation. My question has to do with how to add two resultant prisms together. Ditto subtraction. Say I have RE 2.36@334 and wish to add 1.09@ 321 to it, is there a calculation that does it simply please?

If it helps for prism, the way I understand it is; PT PD is Right eye or (OD) 31mm and it was received at 33mm, that 31-33= 2mm BO (base out) because the received PD is larger than the PT PD. In the OD the prescription is a minus lens (-) when the RX is minus we change the base to the opposite direction, in this case meaning BI. If the RX was in a plus lens (+), then we keep the same base direction meaning that our base would stay as BO (base out). Hope this helps! Great videos, I am refreshing my memory for my BOARDS!

Guys if it helps, the way I think about how to know what type of prism it is: PT PD is at 67 and Glasses were made at 60, so we know that is BI because the glasses came with a smaller PD than the one, they were supposed to have. Then I looked at my prescription in the eye that am I working on. If is a (+) plus lens, then the prism stays in the same direction BI. If is a (-) minus lens, then the prim is the opposite, in this case BO. Hope this helps! The videos are great and very helpful now that I am getting ready for my BOARDS and needed a refresher.

speaking of minimum seg height (18), i also require that the patient has at least 9 mm from the fitting cross / center to the top of the frame for distance viewing (10 or more is ideal, 9 still ok in my experience). whether or not the frame has nosepads makes a huge difference in deciding if these factors will cause me to reject the frame, due to adjustability or lack thereof.

Those things cost like $80+ for a pack of 25. That's 25 pairs of pads, not 25 total, so 50 pads. Everyone loved them and asked for them. Air-Active I think they're called that.
