Evaluation of ocular health and comfort of spectacle wearers for three months

This study is looking at how the eyes and comfort of people who wear glasses change over three months. By studying spectacle wearers, researchers hope to better understand what causes discomfort in contact lens wearers. Participants will attend a few check-up visits where researchers will examine their eyes and ask about comfort. No new treatment is being given — this is an observational study of regular glasses wear.
