If you have been diagnosed with multiple sclerosis, you may have experienced double vision along the way. If so, you were told of two options: wear an eye patch or get a prescription for prism glasses.
There is nothing more humbling than wearing an eye patch. When you first do so, you need to make peripheral adjustments for the patched eye. Walking into walls or people was common for me, back in 1999, when I acclimated to using just one eye.
Once the double vision, known as diplopia, became less transitory I was able to get a prescription for prism glasses. The first two prescriptions didn’t work out too well.
Prescribing prisms seems to be beyond the scope of most retailers who sell eye glasses and rely on a staff optometrist to write scripts.
So I went to see a neuro-ophthalmologist who understood the visual deficit and corrected it using a specialized prism that turns two images into one.
When adjusting to the new lenses you have to wear them as much as possible. You may feel episodic dizziness, fatigue and nausea during the adjustment period.
It felt like I was looking through a fish bowl for about a month until I got used to my new glasses. The prisms never adjusted perfectly and probably never will -- but the doctors won’t tell you this.
And just like a fish bowl, someone looking at you from the outside may see you as having normal vision. If only they could walk a mile wearing our glasses.
