90D Double aspheric Ophthalmic Lens in Wooden case, Express Shipping

I'm a 4th-year US medical student going into ophthalmology. I had tried different lenses from the residents and attendings and became accustomed to performing an indirect examination. However, due to the speed of cases in the clinic, I often found myself examining patients by slit lamp without a lens (as it was required for the teaching physician in another room), and wishing I had one to practice my skill, especially when the patient had retinal pathology. I took a chance on this one, and am more than pleased. I think it's a perfect medical student lens. I'm able to evaluate the retina and have a clear image to examine any pathology. It lacks the anti-reflective coating on the gold-standard VOLK lenses, but this can be managed with tilting and some practice. Not really a concern, especially with this lens being a 15th the price of VOLK.

I feel like other lenses you're paying for a brand name. The metal casing for this lens feels like the size of a 78D. So if you prefer the smaller feel of the 90D, you might want a different brand. But it barely any different in my opinion so everything is great. Clear image, good magnification, magnetic box is nice.

Optometrist here, not permitted to dilate patients as part of my local licensing regulations. I use slit lamp funduscopy mainly for screening purposes, and was exploring affordable 90D lenses to work around smaller pupils where my Volk 78D felt a little limited.Not bad for the price. Lens is uncoated, so has more reflections than the premium brands, but otherwise tried it side by side with my Volk 78D at the same slit lamp (and on the same patient), where it worked well enough comparably on undilated pupils.Would suggest this as a decent backup lens for students, rural outreach work, or other situations where you'd rather not risk bringing a better lens. Definitely worth it in that regard.

The inside is loose and I’ve only used it for a month

This ended up being a lot better than I expected! A lot more affordable than a Volk. It is a larger lens than a typical 90D - not quite the size of a 78D, but in between the two. It also has a more magnified image than a typical 90D, which once again was not quite as magnified as a 78D but something in between the two if that were to exist. The image quality is good and I haven't noticed issues with glare. Overall very happy with the purchase and it is definitely worth the cost.

Wish it had a small manual, I fear that I clean it with spirit and it becomes permanently blurred. A manual could help. But I love it notwithstanding

Buenos materiales, el reflejo es alto, sin embargo es lo esperado por el precio de la lupa. Para residentes que se inician en fondo de ojo es adecuada. Buena relación calidad-precio.
