90D Lens Description
•   The Bawa 90D is the most widely known fundoscopy lens and is to date considered the gold standard in exam rooms across the world. The small profile of the 90D coupled with its optical profile makes it a great first lens. This lens is a perfect choice for general examination and retinal imaging. This lens can be used to get through small pupils for patients who do not prefer or accommodate dilation and as a result is also a popular choice for undilated retinal exams.
