International Conference of Opthalmology, 1962 - Stamp, First Day Cover

शस्तं सर्वाक्षिरोगेषु विदेहपतिनिर्मितम् 

śastaṃ sarvākṣi-rogeṣu videha-pati-nirmitam 

"That which is founded by the Lord of Videha is the excellent in all eye-diseases"

So said, the great Vāgbhaṭa, in the Astāṅga-hṛdaya Samhitā, Uttarasthāna, Chapter 13, Timira-pratiṣedhādhyāyaḥ, Śloka 27.

This Sanskrit verse found a place on the commemorative stamp issued on 3.12.1962 on the occasion of the International Conference of Ophthalmology. An FDC and brochure too were released.

The science of eyes is called Opthalmology. It was called the Nimi Tantra in ancient India because the founder of the system of treatment was the reputed Nimi, the King of Videha. 

It may also be noted that in Sanskrit closing or winking of the eyes is known as nimi. Accordingly, the measure of time for a wink is denoted by the word nimeṣa, a second.
