Visibly is not a replacement for a comprehensive eye health examination. Our licensed Ophthalmologists and Optometrists use Visibly's online technology to evaluate a patient's visual acuity and a portion of the ocular health profile and issue a prescription for corrective eyewear, where clinically appropriate. Visibly's services are limited to patients between the ages of 18 and 50 who are in good health. Because Visibly's services are not a replacement for an eye health examination, we encourage everyone to obtain a comprehensive eye exam at least once every 2 years. We prohibit patients from taking a Visibly exam more than 4 consecutive years without certifying that they have received a comprehensive eye test first.
