    Rx Sunglasses

    Can anyone tell me why prescription sunglasses are generally less dark than plano sunglasses of the same type and model? In general a sunglass bought off the shelf would be more darker than the same sunglass made into Rx; why is it so?

    Sunglass demo lenses could be made from anything and from anywhere. They could be tinted or polarized and with or without backside reflective coating or mirror. We have had issues in the past with offering polarized gradients because 90% of the time they won't match any demo. I always show an example of the lenses that will be used when adding the Rx so the patient knows exactly what their lenses will look like. If the demos come with a special coating, as stated above, I will be sure to offer them separately whereas they won't automatically be added on.
    Have I told you today how much I hate poly?

    I'm having problems too with customer expectations. They have a choice to buy plano polarized sunglasses or to get the same sunglasses as Rx. The problem arises when the Rx are not as dark as the plano ones. The lab is also not giving me the option to get them darker.

    Two words: flash mirror coating.

    Coppertone and Xperio lenses are the two darkest I've seen, flash mirror coatings are great. And I agree with Quince - HAVE SAMPLES they can see through before they decide, no surprises, no returns. Forget showing them on a website or app what it will "look like" nothing is as foolproof or effective as demos of the exact lenses you will be selling them.

    And a good part of the time, I agree: the polar lenses don't look dark, in a mirror.

    Ergo, flash! You can't see your eyes = "they're dark!"

    Most of the planos on the market are vacuum coated tints, which explains two things. One, they can be applied on all materials, and two, they are uniformly consistent and dark. Ophthalmic lenses are limited by the tintability of the material and/or the hard coat. Having samples on hand to show your patients what your labs (outside or inside) can provide is key.

    That is super helpful to know! Now I have an actual explanation to back why it can be so hard to match demos for certain frames.

    Very simple, there are millions of pre-finished sunglasses sold every year of the shelf to the public for protection against bright light and UV protection and fashion and comfort.

    The darker type lenses are the most sold ones, of the shelf.

    If you get Rx lenses you have all the possibilities from light to dark coatings as you want and so forth and you pay the price for whatever you select and get.

    Probably because most consumers think darker is better, that white fabric tinted blue makes it look whiter, music limited dynamically to sound louder is better, that heavier cars can turn and stop faster than lighter vehicles, etc.
