Spectacle modification solutions for people with blepharotosis

Ptosis Props

We only use skin contact safe materials in the production of ptosis props. Our comfort sleeves are manufactured from platinum cured silicone. This high quality material is durable and non-yellowing with zero peroxide by-products.

Please note, we can upon request supply an alternative hypoallergenic sleeving if the wearer exhibits non-tolerance or reaction to silicone-based materials.

We manufacture optical appliances with comfort and well-being paramount in the design process. That is why our props are designed to deflect accidental impact energy.

What is “Ptosis”?

Ptosis‘ (toe-siss) or ‘blepharoptosis‘ is drooping of the eyelid a condition where the upper lid drops and cannot be kept open by normal action of the muscles.  A ptosis prop or ptosis crutch is a device used to retain the upper eyelid in a position considered more normal.

Drooping of the eyelid is caused by the reduced function of the levator palprebrae (extra-ocular muscle which controls eyelid elevation).

What causes Ptosis?

There are many potential causes of this condition. Here are some of the most common.

  • Blephospasm
  • Myasthenia gravis
  • Congenital ptosis
  • Aponeurotic (age related) ptosis
  • Nerve damage (cranial injury)
  • Horner’s syndrome

The effect of ptosis can be corrected by the spectacle modification methods listed on this page.
