Keratoconus sufferers have been told of their contact lens options in a recent lecture.
Martyn Lewis and Lynn White of UltraVision gave their deliveries to Moorfields Contact Lens Department at Moorfields Hospital.
It was explained how people with keratoconus no longer need to wear rigid contact lenses but can now opt for soft ones instead.
Mr Lewis spoke about Definitive, an advanced silicone hydrogel substance for making contact lenses.
After that, Ms White gave a presentation about UltraVision"s contact lenses for people with keratoconus.
The company says that people who wear soft contact lenses for keratoconus can keep them in comfortably for up to 18 hours.
Keratoconus is a condition in which the corneal tissues can thin, changing the shape of the eye.
According to the RNIB, it rarely develops until a person has hit puberty or is older.
It causes distortion of vision and in extreme cases a corneal transplant may be necessary if contact lenses can no longer correct the sufferer"s sight well enough.
