With the widest field of view in the BIO lens range, this lens offers visualization out to the far peripheral retina albeit with a lower magnification of 1.67x. This lens can be used to bypass small pupils or for quick dilation free BIO examination. A preferred choice in pediatrics for the same reason, this lens is a popular choice when working with infants with retinopathy of prematurity or examining the peripheral retinal health in patients of any age. Thus this lens is a great choice for quick screening and may be followed up with a higher magnification exam if and when an abnormality is suspected.

Comes with a complimentary case. Please allow 6 weeks on orders with custom engraving.
