I have had 6/6 vision for the first 34 years of my life, but recently started experiencing blurred vision in my right eye at some times (at other times, my vision is clear). This blurring coincides with the birth of my son, because of whom night-time rest is disturbed. I checked with a local opthalmologist, and she said I have a weak eye. She suggested wearing glasses and said that my eyes will not get better. Is the diagnosis accurate, and is there any treatment?
