Pupil torches and diagnostic penlights for PERRLA pupil assessment and clinical examination – disposable, reusable and rechargeable options. The range covers a clip-on torch that lives on a lanyard or pocket, coloured reusable torches, and a USB rechargeable model that removes the battery cost from a device used many times a day. All give a focused white beam bright enough to assess pupil reaction without dazzling the patient, and most carry a pupil gauge printed on the barrel.
