    134 indicates that this is a prescription for glasses and not lenses. Lenses are typically only available in increments of 10.

    If that’s the case, you should get a new prescription specifically for lenses, because the spherical correction (-4.5) will also be different between glasses and lenses, because of the distance to the eye.

      What’s the difference between glasses and lenses?

      I need to understand this before Labor Day, I have to renew my driver’s license, and that’s a restriction on my license.

      Class R - Regular Operator’s License

      Restrictions 1 - Corrective Lenses

        I’m not aware of your laws, but isn’t it just self-certification? Like you tell them “I use glasses to have normal vision” and they reply “okay cool” and write corrective lenses on your license?

          Um, the Department of Motor Vehicles does a crude eye exam too ya know…

          They gotta make sure drivers can read the road signs, which I cannot without corrective glasses or contacts.

            An your current glasses are so insanely scratched that you can’t pass said test?

              Some people look me in the face and express concern that I might not see well through the scratches. And they’re not wrong.

              What is wrong though, is people insisting that I get a new eye exam, as if they’re my opthalmologist or something…

              My current prescription is fine, although technically outdated. All I need is new lenses that aren’t scratched to hell and back.

              And all I asked was how to actually read the chicken scratch on the prescription…

            Sure, but typically you can only get contacts in specific strengths (increments of 10 as the other person said), while they can grind the glasses lenses to pretty much anything. So you usually get a different prescription for contacts.

              Well, my last opthalmologist (before COVID lockdown and Walmart as the only fallback) gave me the best prescription I ever had, but it’s now outdated.

              I’d like to go back to my old opthalmologist, but he’s now quoting me over $300 for a new prescription and pair of glasses…

                  I prefer the quality of glasses he offers though, they don’t scratch up like Walmart shit. My last prescription would do me just fine, if only I could get them new in a new set of frames.

        The correction is typically slightly lower than for glasses, but besides the corrections (sphere, cylinder and axis), lenses also have curve (BC) and diameter (DIA) to fit your eye.

        If you have an old box of lenses you can usually find all the numbers printed on the side.

        I only use lenses occasionally, so when I recently ordered lenses online using the info from an old box and correcting for the change in my glasses since I had the old lenses, I could sort of figure it out, but they are probably still off by 0.5 or so.

        I think you’re better off seeing an optometrist than guessing.

          I think I’m better at asking my neighbor for his old glasses which I can see crystal clear through than trying to piss $300 through a $30 bladder.

            Optometrist for a new prescription. Not for new glasses. Get your glasses through any of the various cheap online retailers Zenni, lensdirect, etc. Contacts are harder to find for cheap and most will ask for a more up to date prescription to fill.

            Costco does exams for $60.

              My preferred optometrist has a 3 month waiting list. And the nearest Costco is 42 miles away from me.
