    Crizal Prevencia- what you need to know

    Crizal Prevencia is a No-Glare lens that blocks out specific wavelengths of  blue light from reaching the patient’s ocular tissue.

    It is basically an Anti-Reflective (AR) lens, similar to standard Crizal® No-Glare treatment, except it is specific to blocking the narrow band of blue light from 415-455 nanometers (nm) which is specifically the “retinal damaging” light.

    The Crizal Prevencia lens does not block the 480nm spectrum and therefore will not affect suppression of melatonin, the chemical that regulates the sleep/wake cycle. This is a particular advantage for patients that would like to keep their sleep/wake cycle untouched. It is something I tell patients about and is a great way to convey the value of this lens

    This lens is completely clear, unlike other  competitive yellow blue-blocking lenses. This is a great choice for those who do not want a “socially awkward” yellow lens. This lens does have a purple hue on the front side, that can been seen under certain conditions and it indicates that the lens is actively blocking harmful blue-violet light!
