-Be of East Asian ethnicity (either Japanese, Chinese, Taiwanese or Korean);
-Be willing to comply with the wearing and clinical trial visit schedule as directed by the investigator;
-Have ocular health findings considered to be “normal” and which would not prevent the participant from safely wearing contact lenses;

Can healthy volunteers participate?
Yes
Key exclusion criteria
-Any pre-existing ocular irritation, injury or condition (including keratoconus and herpes keratitis) of the cornea, conjunctiva or eyelids that would preclude contact lens fitting and safe wearing of contact lenses;
-Any systemic disease that adversely affects ocular health e.g. diabetes, Graves disease, and auto-immune diseases such as ankylosing spondylitis, multiple sclerosis, Sjögrens syndrome and systemic lupus erythematosis. Conditions such as systemic hypertension and arthritis do not automatically exclude prospective participants;
-An active corneal infection or any active ocular disease that would affect wearing of contact lenses;
-Use of or a need for concurrent category S3 and above ocular medication up to 12 weeks prior to and during the trial;
-Use of or a need for any systemic medication or topical medications or participation in any clinical trial which may alter normal ocular findings/are known to affect a participant’s ocular health/physiology or contact lens performance either in an adverse manner or risk providing a false positive.
N.B. Systemic antihistamines are allowed on an ‘as needed basis’, provided they are not used prophylactically during the trial;
-Eye surgery within 12 weeks immediately prior to enrolment for this trial;
-Previous corneal refractive surgery;
-Contraindications to contact lens wear;
-Contact lens wear within 1 calendar day of initial lens fitting (washout period to be performed post enrolment if necessary)
-Allergy or intolerance to topical anaesthetics

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be randomly allocated (allocation concealment performed by central randomisation by computer) to wear each lens type (Focus 1-2 week, Focus Monthly and Freshlook Handling tint) for 1 month each over a 3 month period. The person who determined if a subject was eligible for inclusion in the trial was unaware as to which group the subject would be allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation list (which will be generated by computer) will be generated based on a crossover design where each subject receives all the study products.
Masking / blinding
