Excellent teaching tool to review the basics in an entertaining way. These subjects can be mastered–your videos help instill those first steps of confidence to go deeper.

I love your impressive lectures! Those are really useful and quite easy to understand the theories for Mandarin optometry students.

Excellent! Informative and entertaining lecture series, thank you. I am currently working on a project aimed towards the semi/full-automation of slit lamps for telemedicine applications. I’m interested in knowing more about the video sources you used in your presentation.

Hi Dr. Root,

I am part of the Rhode Island Optometric Association continuing education committee. I was interested in finding out if you provide webinars or live lectures for optometric continuing education (CE credits). We are looking for speakers for 2015, and you are in high demand!

Thank you, Audra

I love your lectures. They’re aimed waaaay above a medical student’s level, yet remain so easy to follow. They’re fun, with just the right level of childish humour and I just wanted to say thanks really – stay awesome! :D

I cannot say enough about this physician. From his gentle way to his cartoon buttons (in the office) – he is super. I was a bit worried when I had to leave my doctor in NY but when I found Dr. Root, I asked her (Dr. Cynthia Parlato) if she would ‘check him out’. She did and sent me a personal letter saying that she thought I had made a very good choice. That was enough to entrust him with my eyes. My husband just had a cataract removed and I continue to be impressed with his expertise and gentle way. By the way, his office staff team is super.

Hi there Dr. Eyeman I hope you are doing fine with your life and career. I thought of passing by and say hi.

I really loved your ophthobook, it’s made my life easier and helped me love, enjoy, and understand what I read and study. When I thought about your way in writing and simplifying informations I wondered if there is another medical books that followed your wonderful way of discussing things, so, I said to myself let’s go and say hi and ask Mr. Tim Root about it.

I am a poor medical student who’s trying to build up his knowledge on strong bases, so if you know any other books writers as great as you who made a book that’s easy and simple just to understand things on simple bases.

Sorry for making this long enough, I hope a very good and happy life for you and thank you very much for making such a great book.

Fantastic videos and speeches! I learned a lot from these materials. Thank you so much!

I’m a third year medical student from India. I discovered you on YouTube and have been reading ophtha book for a while now. Today I went to an ophthalmology lecture taken by our HOD, and he played your video on optics in the class! It was like seeing an old friend unexpectedly:)
The world needs more educators like you. Thank you so much. People like you keep my morale high about becoming a doctor.

Hi Dr Root,

Brilliant lectures – I am currently revising for my Part 1 Ophthal exam over here in the UK and your lectures provide succinct summaries that are incredibly user-friendly. I was wondering if you could possibly answer a question: how does the Maddox Rod test have to be adjusted for someone who is red/green colour blind?

Many thanks.
