Hello, Thank you for the question.I am Dr.A.S.Desai and I look forward to assisting you .
What is the power of your glasses at present?
Do you have the prescription for it? If so, could you give the details of it? Are you wearing glasses for distance and near both?
My presecription is +.75 in my right eye and -.75 in the left.
I don't see object far off as well, so I am nearsighted.
Do you have to wear your glasses for near work as well?
Are the present glasses monofocal/bifocal /progressive glasses?
Typically no, but I did notice recently that my eyes can sometimes strain, like when reading the newspaper or a book.
I understand that the near vision must be bothering you in recent times as you are setting into presbyopia. Presbyopia is a natural age related phenomenon in which the near point recedes with increasing age.
Since you are wearing glasses which correct your distance vision only, I guess the strain which you are experiencing off late is due to the onset of presbyopia ( begins around the age of 40 years in most individuals).
The small minus power in your left eye was probably helping you to overcome the initial phase of presbyopia. Normally presbyopia is corrected with convex(plus) lenses.
The -0.75 D in the left eye probably negated the +1.0D required at 40 years. But this presbyopic correction goes on increasing year after year which is why you have begun to experience eye strain now. I guess it would be better to go for a near correction as well and depending on your requirement you can opt for progressive glasses.
I see. I will mention this to my ophthalmologist at my next appointment.
I hope you had a complete eye exam during your visit to the ophthalmologist including the dilated eye exam ( to look at the back of the eye).
Is there anything else that I can answer for you?
Yes, one more question if you don't mind.
Please do go ahead and ask.....
When I am not wearing my glasses, I will sometimes experience some dizziness. The best way I can explain it is I feel a bit disoriented as a result of my vision. Even though I can see objects far off, and they are not blurry, it feels as though my eyes are straining to see. Like I'm not really there, but in a dream?
And I sometimes feel a bit disoriented. Not sure this is a result of my vision problems.
I don't think that the difference in the power of the two eyes could have been the cause of disorientation ( the difference should be more than 3 dioptres to cause visual problems)
There are many other conditions which can cause dizziness including ear and cerebellar ( brain) problems.
Benign paroxysmal positional vertigo (BPPV) is one of them. You can discuss this with your ophthalmologist at the next visit.
Sounds good. Thank you for your help.
You are most welcome.
