SOFT CONTACT LENSES

 

Safe-gel 7 days

 

A brand new product, from the laboratories of Safilens, Safe-gel 7 days proposes, through its innovative use of new generation materials, geometry and production technology, to set new standards in quality, safety and comfort as well as new opportunities for the contact lens professional.

 

 

The Material 

The revolutionary material used in the safe-gel 7 days is made up of two polymers (bipolymer):

Filcon 1B and the natural biopolymer Hyaluronate gel.

The polymer Filcon 1B is the solid structure of the lens. The biopolymer, Hyaluronate gel is the soluble substance, enriched with the active minerals calcium, magnesium and potassium, found naturally in the tear film.

 

 

 

 

Advantages 

            One of the most frequent pathologies or causes of discomfort amongst contact lens wearers is an insufficient tear film or an alteration in the tear film quality. 

            Recent studies show that this situation is caused by the numerical reduction of the mucin producing caliciform cells, consequently leading to a reduction in mucin. 

            The slow release of the Hyaluronate-Gel, thanks to its mucomimetic effect, helps to maintain and renew the volume of mucin in the tear film, significantly reducing

 the most common symptoms of dry eyes, normally associated with: 
 

  • rubbing of the tear film (wearing contact lenses)

  • environmental factors (wind, light, smoke, dry air)

  • visual factors (video monitors, reading, detail work)

  • Chemical pharmaceutical factors (eg. contraceptive pill, anti anxiety medication, antihistamines)
