Another explanation [of why Isaac is mentioned first]: It is the way of a woman to sit at home, and the way of a man to go out and learn understanding from other people. But this one [Isaac], because his eyes had dimmed and he sat inside his house [and could not go out to ease his mind among people], therefore Isaac is mentioned first.
A Man Goes Out and Learns Wisdom but Blind Isaac Stayed Home
Yalkut Shimoni on Torah 113:3
דָּבָר אַחֵר וְכוּ' אֶלָּא דַּרְכָּהּ שֶׁל אִשָּׁה לִהְיוֹת יוֹשֶׁבֶת בַּבַּיִת וְדַרְכּוֹ שֶׁל אִישׁ לִהְיוֹת יוֹצֵא לַחוּץ וְלוֹמֵד בִּינָה מִבְּנֵי אָדָם, וְזֶה עַל יְדֵי שֶׁכָּהוּ עֵינָיו וְהוּא יוֹשֵׁב בְּתוֹךְ בֵּיתוֹ לְכָךְ לְיִצְחָק תְּחִלָּה.
