I plunged into the EM protocol yesterday with differentials for close-up work. These are 1.25 D difference from full strength - single vision without CYL correction. I have 2 monitors in front (60cm), 2 on either side with 80 cm on near side. Keyboard at 30cm. No blur for the keyboard. Manageable blur on the front monitors. More blurry on the side monitors. I also have a monitor above head level which is also 80 cm at the bottom edge.
My experience as follows: No problem with the keyboard. I can even practice/try Active Focus on the front monitors. I have to turn and lean forward a bit to see the side monitors. Workable so far. As long time wearer of progressive lenses, I have developed the habit of moving my head to scan up and down rather than my eyes. I really need to mindfully avoid this. When I move my eyes, I can focus and see better, which is lost when I raise the head to look through the bottom of the lenses. Perhaps I should wear a neck brace till I break this habit. I realized that neck and shoulder muscles are overworked and stressed because it was very relieving, when I stopped moving my head. This is Challenge #1.
Challenge #2 is trying to actively focus on the content on the screens. Screens full. of ever-changing numbers. It is especially hard with numbers 6, 8, 9 when they occur together in various combinations. At 80cm distance, I have to turn and lean forward to make them out. At this point, it seems to me I should stick to static text for AF exercises and get a new pair of differentials with more correction. for regular close-up use. Interestingly I can view the side screens more sharply from the corners of the eyes as opposed to turning my head & looking straight. Not sure if this is an artifact of the lens distance changing the focal plane or the celiary muscles relaxing a bit. I suspect it’s the former.
I am also debating whether to get a lens kit to figure out the best correction for the differentials for my situation. I thought I would share the experience of an EM novice and welcome comments/suggestions.
