Use a chair that provides good back support. Sit close to your work surface. Remove false fronts and supplies from under the bench work area. Avoid leaning on hard edges. Pad forearms and edges. Keep elbows close by your sides. Work with wrists in straight, neutral positions. Adjust your chair, workbench, or microscope as needed to maintain an upright head position. Elevate, tilt or move the microscope close to the edge of the counter to avoid bending your neck. Use adjustable eye-pieces or mount your microscope on a 30° angle stand for easier viewing. Keep scopes repaired and clean. Spread microscope work throughout the day and between several people, if possible. Take breaks. Every 15 minutes, close your eyes or focus on something in the distance. Every 30-60 minutes, get up to stretch and move.
