The Volk 90D is considered to be the gold standard in the ophthalmic industry for slit lamp exams across the world. The small profile of the 90D coupled with its optical profile, provides wide-field viewing, superior image quality and enhanced clarity, making it a perfect choice for general examination and retinal imaging. This lens can be used for small pupils for patients who do not prefer or do not accommodate dilation, making it a popular choice for undilated retinal exams. All Volk lenses are made in the USA and each lens comes with a free Volk single lens case. The Volk 90D condensing lens also lends itself to veterinary applications, for diagnosis of retinal pathologies in animals. The 90D slit lamp lens is available throughout the year in 7 standard colors. Special limited-edition pink lenses are announced periodically on our social media platforms. Volk Optical warrants its Non-contact Slit Lamp and BIO Lenses against defects in materials or workmanship for a period of 10 years from receipt by end user.
