Behavioral habits of contact lens wearers

In this study we propose to investigate the impact of contact lens (CL) packaging displaying a ‘no water’ logo/graphic and evaluate whether this affects wearers’ behaviours and attitudes to CL care/ wear. Two hundred established daily wear CL users will be recruited as study participants. CL wearers may use CL at their own discretion. Participants will be randomized to two groups, test and control. Test group will include those who will receive written instructions + “no water” graphic while control group will receive written instructions only. At baseline visit after being randomized, each research participant will receive a package which includes a pamphlet containing general instructions on safe CL use and one new CL case with or without a “No water” graphic sticker. The written instructions pamphlet has already been used in various publicity and awareness campaigns of School of Optometry and Vision Science, UNSW. The stickers will be attached on the top surface of the lid of CL storage case. Pre-made packs- some with stickers and some without will be given out randomly according to a randomization sequence. A masked investigator (PhD student) will deliver the packaging to each participant. At the follow up visit (six weeks interval), the participants will return their storage cases with/without the "no water" logo and will be given a replacement of storage case on conclusion of study. In order to track participants' CL wear schedule, they are asked specific questions regarding CL wearing routine at both baseline and follow up visits.
