Optometrists, there training is strictly in eye exams and vision correction with glasses or contact lenses. Others treat eye disease or conditions. Hubby has Retinal Atrophy from heavy metal cleaners in the Navy, has holes in Retinas, and now severe Glaucoma. Have my own issues with Dry Eye from Cataract implants and Lasix. Plus drugs that mess with your vision.
Blurred vision does not help spelling errors.
And i make plenty with arthritic fingers. You have my sympathy.
