Study Details

Brief summary:

The goal of this clinical trial is to \[primary purpose: is to determine if Total30 Multi focal toric conntact lensesare comfortable and the willigness for those who have previously worn reusable toric contact lenses are willing to stay in Total30 MFT after 1 month of wear during the duration of the study. Healthy previous reusable toric contact lens weareres will be refit into total30 MFT contact lenses and will be asked to gauge their comfort while wearing the lenses. Healthy adult participants who are presybyopic between the ages of 18-40 can participant, sex and gender are not disqualifiers unless the participant is pregnant or breast feeding. The main question\[s\] it aims to answer \[is/are\]

\[primary hypothesis or outcome measure 1Proportions of toric CL wearers who have positive visual acuity scores in comfort and vision after one month of wear.

\[primary hypothesis or outcome measure 2\]? Contact lens dry eye-8 scores will be less than 12 indicating high levels of comfort after one month of wear.
