I seem to have the sugar levels better but now from 17 average to 5.7, and I knew I needed new glasses as my eye site had changed in past 5 months, but the optician has said I have cotton wool spots in my one eye . So is this a perment thing and as long as I keep my sugar levels low will they go away or is that it for the eye as the damage will be permanent? Waiting to see specialist now as urgent review, read some horror stories that it will progress not fixable etc.
