In 1st Chronicles 4:17, a man from the tribe of Yehudah by the name of Ezrah is listed as follows:
And the sons of Ezrah: Jether, and Mered, and Epher, and Jalon. And she bore Miriam, and Shammai, and Ishbah the father of Eshtemoa-- וּבֶן-עֶזְרָה--יֶתֶר וּמֶרֶד, וְעֵפֶר וְיָלוֹן; וַתַּהַר אֶת-מִרְיָם וְאֶת-שַׁמַּי, וְאֶת-יִשְׁבָּח אֲבִי אֶשְׁתְּמֹעַ.
This particular Ezrah's name is spelled with a "ה" and means "help", "aid/succor", and possible "enclosure".
Ezra HaSofer's name is spelled with an "א". This website makes a claim that due to that Ezra HaSofer's name could possibly mean "Strong Vision".
Is there a significant or particular reason for this (perhaps due to Aramaic influences)? Does the "א" significantly change the meaning of the name from "help" or "assistance" to something else?
