I recently had to "upgrade" to bifocals. Due to partial right visual field loss, I was told I should get lined bifocals as opposed to progressive. I also got a low-level tint, and that has been great.
I have however noticed an increase in migs. Now, this is a bad time of year for me trigger-wise because of allergies and multiple storms that have moved through this spring. Perhaps that is the cause. My fear is that my new bifocals might be triggering some of this. The line in my right lens crosses exactly where my visual aura traditionally occurs.
Could this just be a coincidence? Maybe this is just a bad spring, and I'm grasping at straws. Any input would be appreciated.
