Bifocal ML Optio solution
Activities and use
The patient remains active in the academic world — travelling, giving lectures, writing articles and similar tasks.
He uses bifocal glasses for reading when CCTV (magnifying systems) is not available.
The glasses are also used for computer work, both for reading and navigating the screen. The patient additionally uses ZoomText (magnification software).
The distance segment is used to view the keyboard, while the near segment is used for the screen and for reading shorter texts with large print.
Without the filter tint, the patient experiences reduced clarity — everything appears covered by a whitish haze.
Reason for visit
The current glasses are worn and scratched. They are used extensively and are taken in and out of his pocket many times each day.
The bifocal glasses has the ML527 filter tint, with the segment positioned in the upper part of the lens — similar to an aviator-style design.
Adjustment
At the last adjustment (around three years ago), the segment was lowered to create a larger, easier-to-access field. However, this turned out to be too large, and the patient now wishes to reduce it again, and have it moved slightly upward.
Current prescription
Right eye:
+2.50 D / cyl -0.50 D 10°
Addition: +9.50 D
Left eye:
+2.50 D
Addition: +9.50 D
New prescription
Right eye:
+3.50 D / cyl -0.50 D 10°
Addition: +10.50 D
Left eye:
+3.50 D
Addition: +10.50 D
The patient experiences sharper letters when he can see text or the screen closer.
Solution 2 – ML Aplanat
The patient has previously been using an Aplanat system but has noticed that the current power of +20 D is becoming too weak. During testing, both +24 D and +28 D were tried, with +24 D providing the best result.
Filter tint: The patient wishes to keep his current ML527 filter tint.
