Summary

The aim of this work is to undertake a range of vision-related measures with soft toric contact lenses soft spherical contact lenses and spectacle lens correction across a range of levels of astigmatism.

Detailed description

This will be a randomised, crossover, partially subject-masked (for contact lenses only), non-dispensing study, controlled by cross-comparison.

Conditions

• Astigmatism

Interventions

Type	Name	Description
DEVICE	Soft Toric Custom Made Contact lens	Subjects will be randomized to wear soft toric custom made lenses for 30 minutes in one eye with other eye patched.
DEVICE	Soft Spherical Contact Lenses	Subjects will be randomized to wear soft spherical contact lenses for 30 minutes in one eye with other eye patched.
DEVICE	Spectacle Correction	Subjects will be randomized to wear spectacle Correction for 30 minutes in one eye with other eye patched.
