    What is a Myodisc Lenticular Lens?

    Hi there!

    I'm new to the forum but am hoping someone could help me out. I'm looking get new glasses for the following prescription:

    sphere cylinder axis
    -6.00 -1.75 170
    -6.00 -1.25 180

    I have the option of getting high index lenses or Myothin Lenticular Lenses.

    What are lenticular lenses? What's the difference between plano base and bi-concave? How do these lenses differ from normal ones?

    Thanks for the help...

    Lenticular lenses or miodiscs are used only for very hig powers like double or triple of what you have. They have a little 38 - 40 mm circle on a plano or even concave base curve. The outside curve is the base curve. Plano means flat and concave means curved to the inside. These lenses are flat and light, but you will look like a blind person.

    Totally not suited for a normal minus Rx as you have. Get yourself a good normal high index lens and you will be happy.

    Agreed, no reason to go to a myodisk with this Rx. I would suggest a 1.67 index with AR coating.

    thanks...

    Thanks for clearing that up.

    Okay...a couple more questions. Will there be a significant difference between High Index 1.8 glass vs 1.67 resin material? Is hard resin the same as polycarbonate?

    I guess my goal is to have something that is thin while still comfortable. I believe I currently have 1.67 Seiko lenses.

    Depending on the size of your frame and your pupular distance I cannot see a 1.8 glass being any thinner than 1.67. A 1.67 is different that poly, and is thinner.

    Okay...going for the 1.67. Thanks!

    Just as an academic exercise. Is it possible to find the difference in edge thickness for my prescription comparing 1.67 AS to 1.8 glass?

    PD = 63mm

    Frame Size
    47mm lens width
    27mm lens height

    Prescription
    sphere cylinder axis
    -6.00 -1.75 170
    -6.00 -1.25 180

    I do not have my charts with me, but I estimate maybe a 0.1 or 0.2mm difference. If you say the bridge size is 18 mm then that is a frame pd of 65, so then you are only 1mm dc per eye. Basically, your eye is pretty well centred in the frame (which is a good thing), so anything higher than a 1.67 will not produce any significant difference.
