    I recently had my eyes tested and my Doc gave me a new prescription. So I went to get a new set of lenses. I was recommended to get the digital bifocal lenses. When I got them everything seemed fine. On the third day the headaches started. They got so bad I had to take them off. I put them back on the next morning and right away the headaches started. Also the far vision area was so high up on my lenses I had to tuck my chin down and almost peer over the top of my frames. That gave me headaches as well. The bottom reading area...I had to look up too high land then with my head way up move my eyes to the bottom of my sockets so to speak to see what was on the sheet of paper to read. More headaches. The far vision the reading vision and the sides were really clear but they seemed to be positioned wrong. Also when I moved my head sideways things swayed like I was drunk. My middle range vision was equal or worse than my old glasses. I thought the lenses were made wrong. This went on for 8 days. I finally put my old lenses in my frame and went back to the dispensing optician store. He checked the lens prescription with my new lens and said it was what my eye doc had ordered. I then had my eyes retested. I was assured the prescription was right. So why didn`t my glasses work. My optometrist said she had run into 3 or 4 possible case like mine and the optician said I could be only the second case. I finally had a new set Essillor Ovation+Poly Crizal Forte lenses made and I can see perfectly. I am told on rare occurrences, some people cannot wear the new digital lenses. I am trying to find out WHY?

    Dr Langis Michaud's response:

    Dear Kelvin

    I have said many times on this blog that the patient is better served when he fills in the prescription at the same location he had the exam, with the same professional. It makes things just easier and nobody can battle about who is responsible of what… In your case, it is obvious for me that the first pair of glasses were wrongly made: the centration was obviously way off and this is why you had these symptoms to occur. This is not because digital bifocal lenses were prescribed. They were not centered well in your frame. In your case, a second problem is that the optician switched a high tech (costly) progressive pair of glasses for an old-generation not-so-sophisticated-but-working-well type of progressive lenses. You bought an Audi and you ended up with a Chevy car demo. Not exactly the perfect scenario. The only good thing is now that you see well and your headaches are over.

    For anyone else who will read this, remember: it is always a better alternative to purchase the glasses where the exam was done…

    Thanks for having shared your story.
