Best Frames for High Index Lenses

Wondering what type of glasses you should be getting your high index lenses in?

High Index Lenses

High index lenses are available in a variety of frame styles, sizes, and types, but not all. In general, the larger and more curved the frame is, the fewer high index choices you’ll have in that frame.

High index lenses are made for regular “street” glasses, meaning that they’re made with regular eyeglasses frames in mind. Because of this, their diameter is relatively small. A large wraparound or sunglasses frame generally has very large lens pockets, which can be difficult or impossible to insert the small-diameter high index lenses in.

If you’re wondering what the best frames are for high index lenses, here are some guidelines to follow:

  • Any “flat frame” style glasses that are made for regular everyday prescription glasses generally work for high index lenses.
  • The flatter your frame and the smaller the lenses, the easier it is to insert high index lenses into the glasses.
  • Large wraparound or sunglasses style frames generally do not work with high index lenses, although they do work with high index 1.70.
  • Aviator frames are not a good choice for high index lenses, though wayfarers and cat-eye glasses are generally fine.
  • There are some cases of larger lenses where the frame is “on the cusp” so to speak, with large lenses that are still small enough for high index lenses. In this case, your pupil distance and lens options will have an impact on whether the frame will work with high index lenses. Contact us to help with this.

Most people shopping for high index lenses and frames are looking for everyday glasses, not specialty prescription glasses such as sunglasses or safety glasses. Because of this, most frames that you’d naturally gravitate towards for everyday prescription glasses should work fine in high index.

      Hi Ray,

      There’s no specific index requirement for your frame. You can get anything from standard plastic up to the highest index plastic. If you want thin lenses, I’d suggest going with high index plastic 1.70 or high index plastic 1.74. Does this answer your question?

    Hi Barbara,

    Yes we can do full rimless drill mount frames with any high plastic index lens material. We do have limitation on how high of a prescription we can do depending on the frame size and your prescription. If you contact us with the frame measurements we can run the numbers and see if they will work.

    Thank You

    I would go with the 1.74 and a small oval shapped frame. Will give you the thinnest lenses.

    Thank You

    Hello, my eyesight in both eyes are -4.75. What frame would be best for me to get with a long shaped face using high index lenses? Also, would a rimless frame look right due to having a long shaped face and high prescription lenses?

    Hello Lucy,

    Generally speaking, if you are shopping for high index lenses, you should go with a frame that has a flat front and a smaller lens size if you want the thinnest and lightest lenses possible. As lens curvature increases (such as in wraparound frames) and as lens diameter increases, your lens thickness on the edges is likely to increase. This means your weight will increase faster than lens size/curve as you move towards bigger and/or curvier lenses.

    If you are trying to disguise the thickness of your lenses then you might want to go with a frame that has a rim. There are many frames that give you the illusion of a rimless frame, but really aren’t. You can always take advantage of trying our frames for fit first before deciding to fill them with your prescription

    I hope I have answered your questions. Should you have any others feel free to contact me directly.

    Thank you for visiting our website. Have a great day!

    I have a -10.00 prescription in both eyes. My contacts have been bothering me so I am trying to wear glasses more. My current pair of glasses has a small frame, and it disorients me because the lenses do no cover the top and bottom part of my vision. Would getting high index lenses allow me to get a larger frame that covers my whole line of sight?

      Hi Justin,

      High index lenses would work for you in a frame that’s large enough to cover your whole line of sight (average sized lenses as opposed to small ones), but you should know that, the larger your lens diameter, the thicker your lenses will need to be. We can make these glasses for you; you can call us at 888-440-9797 or check out our sister site,

      Let me know if you have any more questions!

    Dear sir,

    I am nearsighted and my prescription for the Left eye is -6.00 and Right eye -5. It says 61mm and cycle 2.00. Is it possible to make the glass thinner and by how much? And what type of frames do you recommend?

    I have a -9.5 prescription. The lenses are high index but the lenses still are very thick at the edge of the lens. The frame measures 54mm in diameter. Would a frame measuring say 48 mm in diameter show a thinner lens edge than a 54mm frame? I want to find a frame that would have thin lens edge. As a rule is the narrower the diameter, (54mm vs 48 mm)the thinner the edge?

      Yes the edge thickness would be thinner on a 48mm eye size. If you contact Kyle Ferris at 732-227-4225 or you can email him at he can put your rx in our lab calculator software and give you and exact thickness. So you can see the thickness difference. I hope this helps.

      Yes the 1.74 will work you could even get away with the 1.70 but its up to you.

    I am -9.5 and -8.5 shortsighted. Preparing to buy 1.9 high index glass. Considering two frames: one is 50-16 with 29 height and the other is a bit larger 52-16 with 31 height. Both are rectangular. Can you estimate the difference of the weight and thickness at the edges? I understand that smaller is better, but the larger is also giving me some better angles.
    Thank you!

      Hi Dejan,

      I’m sorry, but that is not an answer I would be able to provide you without having the lenses made with your prescription and inserted into the 2 different frames. To get the thinnest lens, you would be best going with the smaller of the 2 frames.
