    Experts weigh in: What do you wish ODs knew about fitting torics?

    • Science has demonstrated that not correcting as low as 0.75 D of astigmatism leads to meaningful visual compromise, especially under mesopic lighting conditions.

    • Science has demonstrated that masking astigmatism with spherical soft lenses doesn't work.

    • Science, and clinical experience, has demonstrated that toric fitting success with low astigmats is very high (97 percent), with 91 percent successful with the first lens applied1 and takes only about one minute longer than fitting a spherical lens.2

    We are vision care specialists. Let's provide that astigmatic correction!
