Optometrist won’t write letter for drivers licence

I have visual problems since birth (strabismus and nystagmus in left eye). I’ve had LASIK and PRK 20 years ago. Currently the nystagmus is still ongoing as it’s a neurological issue and I have astigmatism in my right eye. Visual acuity is 20/40 in right eye uncorrected and 20/100 in left eye uncorrected. My glasses prescription corrects all of this bringing right eye to 20/30 (progressive lenses). With this should I get another opinion? I am 54 years old and haven’t had a drivers licence because the nystagmus makes parallel park a nightmare. I live in Mississauga and the streets near me Lakeshore and Cawthra are going to get a 1,000 unit condo and subsequently will make my area a food desert, lack of pharmacy services as they’re closing the SDM and there’s no other near me except by car. This is why I’m now considering getting my license at my ripe old age even with the nystagmus in play. There is no services for people my age as I’m not a senior citizen. Sorry if this post is long or may be the wrong flair. Mods if this is not the best place kindly let me know.
