The Optishield offers a flexible hands-free alternative when conducting visual assessments. Made of soft medical-grade silicone, this simple device fits neatly onto the spectacle lens allowing good coverage. A great alternative to occluder paddles, resulting in an examination more comfortable for both clinician and patient. The Optishield also offers a flexible alternative where temporary partial occlusion for a clinically prescribed period has been recommended by an eye care specialist, for example, patients suffering from intractable diplopia (double vision).
