NEAR VISION (reading/writing):
Under room illumination
B/O with +5.00DS BI-PRISM Spectacle magnifier (B-H) able to read N8/1M print size with English newspaper (good speed).
Prefer to read the footnotes (N6/0.8M) with 6x-stand magnifier at
4-5cm from the lens
Prefer to write using felt tip pen (black ink)

REHABILITATION PLAN
Counseling done
To continue with distance vision habitual glasses
Spectacle magnifier (half –eyes +5.00D) for regular reading
Stand magnifier (6x) for reading footnotes
Need felt tip pen (black ink) for writing task.
To stop driving two wheeler and car
