No, wearing glasses doesn't make you the adept of any ideological current, such as transhumanism. At best you could say it precludes you from being an adept of certain ideologies that would oppose wearing glasses, such as very strict "naturalism" (i.e. people who believe it's important to only eat or wear all-natural products), if you want to be self-consistent.
You could also say that wearing glasses or having an insulin pump installed makes you a transhuman, but it can't make you a transhumanist. And plenty of people are perfectly happy to be slightly ideologically inconsistent, or follow more nuanced ideologies, where, say, certain artificial enhancements are allowed and others are not. After all, even the biggest anti-drug crusaders accept coffee or at least tea as acceptable substances.
