As questions and mixed information about how to remain safe during the COVID-19 pandemic continue to circle online, the CDC and data from a new peer-reviewed paper by five prominent ocular scientists confirm that healthy individuals can continue to wear contact lenses.

A five-step strategy, based on functional aspects and pathogenetic considerations, could help prevent the onset and reduce the progression of myopia in children and adults.

The pinhole is well-known to the practitioner to determine the potential vision of a patient without having to perform a refraction. A 1.2-mm pinhole is typical because you can achieve 20/20 vision with ametropias up to 5 D, but above this value a smaller pinhole is needed. We see this in the experiment by Miller and Johnson in 1977 on the “quantification of the pinhole effect,” seen in Figure 1, in which they concluded that a “thin, dyed contact lens may have clinical value for large refractive errors such as aphakia.” Eleven years later, Zacharia and Miller made holes of varying sizes in clear lenses and found significant visual acuity improvement with defocus.

The exponential growth in the prevalence of low vision with age reflects the increased risk of vision loss as a result of age-related eye disease each year, according to researchers utilizing data from the National Health and Nutrition Examination Survey.
