1.74 High Index Lenses for High Index Glasses

There are a few kinds of 1.74 high index lenses that can be used for your high index glasses. What are they, and how do they differ?

High Index Glasses Using 1.74 High Index Lenses

High index glasses have all sorts of options for high index lenses, from plastic to glass, 1.67 to 1.90 index, and all sorts of color and prescription options. If you’re looking to get the thinnest plastic lens high index glasses around, 1.74 is the way to go.

1.74 high index glasses come with a few different options for lenses. Single vision, lined bifocals, and progressive bifocals can all be purchased in 1.74 high index glasses, and the lens colors range from brown and gray tints for any prescription to polarized lenses for single vision or lined bifocals.

These lenses are also available in a limited set of glasses styles. Wraparound high index 1.74 glasses are not possible because the lenses are not made large enough to be edged into a wraparound frame.

If you’re looking for 1.74 high index lenses in your high index glasses, here’s what you need to know:

  • 1.74 high index lenses are available in single vision, lined bifocal, and progressive bifocal prescription types.
  • 1.74 high index glasses can be purchased with clear, brown tinted, gray tinted, polarized gray, and polarized brown lens colors.
  • 1.74 high index lenses are not available in polarized lens colors with progressive prescription types.
  • 1.74 high index glasses are not available in wraparound glasses because the lens blanks are not large enough to be edged into the large lens pockets typical of wraparounds.
  • 1.74 high index lenses are the lightest, thinnest lenses you can possibly get and can be made in the highest prescriptions.
  • 1.74 high index glasses remove the distortion to your eyes that makes them look larger or smaller than they are, making your prescription look less strong and your face look more attractive and true to your natural proportions.
  • If you have a very high prescription and want the thinnest lenses possible, 1.74 high index plastic lenses are the right choice for you. They have the thinnest profile and lightest weight of any high index plastic lens, and they are available in a variety of prescription types and lens colors.

1.74 high index glasses are the most popular high index glasses among people with the strongest prescriptions because of their light weight, scratch resistance, thinness, and attractiveness. As always, if you order high index glasses, make sure you order anti-reflective (AR) coating to reduce the glare cause by high index lenses.

    Hi,

    My daughter has just had some 1.74 high index glasses made. Her prescription is +10(R) and +11(L). the lenses are still double the thickness of her previous non high index glasses (about 1cm) of +8 prescription. I understand the script has increased but was surprised that the high index lenses were still so thick by comparison. Is this right or has the lab made a mistake? My daughter is 5 years old and wearing small adult sized frames.

    Thank you,
    Charlotte

      Hi Charlotte,

      Thanks for your question! There are a few things that could’ve caused this increase in thickness.

      Your daughter’s old glasses may have been aspherical, while the new high index lenses are spherical. Spherical lenses are naturally a bit thicker than aspherical, and this is pronounced with higher prescriptions. This, combined with the increase in prescription strength, could have caused the lenses to be thicker.

      It is of course also possible that the lenses are not high index plastic. It’s also possible that the lab used the wrong base curvature on the lenses, which would make the lenses thicker than they need to be.

      If you have other questions, or if you want to talk about this more, you’re welcome to respond here or give me a call.

    A close friend of mine has -23D myope but he was told 1.74 high index lenses
    Only comes to -20 D. Is there any company that does 1.74 lenses above -20 D?
    He was told his option is only 1.67 lenses in USA or get 1.9 glass from Canada.
    Any other alternatives for him?

      Hi Sam,

      That’s a good question. Your friend can definitely get -23D in 1.74 high index plastic lenses from our sister site, MyEyewear2Go.com. We go to -23 in that material, though your friend will need to pick a relatively small frame with an eye size around 48 or 50. Round lenses would be best as well, so basically I’m suggesting John Lennon glasses. There is some flexibility with this.

      Take a look at their selection here: http://www.myeyewear2go.com/specialty-glasses/high-index-glasses.html

      Let me know if you have more questions!

    Hi
    My eyes’ prescription are +15 (R&L) . How much is 1.74 plastic lense thinner than 1.67?
    and I do not look bad with 1.74?( for example it looks my eyes bigger or smaller than real siza)
    How much it costs?
    Thanks

      Hi Armin,

      In order for us to tell you how much thinner 1.74 is than 1.67, we would need to know what frame you were getting the glasses in and what your pupil distance is. 1.74 will be substantially thinner than 1.67 in your prescription; it will be a noticeable difference. Your eyes will also be less enlarged, though there will still be a slight distortion. It will look much better in 1.74.

      As far as costs are concerned, we’d need to know what color lenses you’re considering ordering, and whether you’re considering ordering single vision or a progressive bifocal. For more information on costs, you can check out our post on lens costs here: High Index Lens Price.

      Please let me know if you have more questions.

      Thanks,
      Kieran

      Hi,

      Please contact Kyle Ferris at at 732-227-4225 or you can email him at kferris@phillips-safety.com. Your rx is not to high and you can probably get away with a 1.67 if you want. Kyle will run the numbers and give you the diffent thickness of the edges so you can make a educated decision.
