Comparing visual performance of two types of daily disposable multifocal contact lenses

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the visual performance of two different daily disposable multifocal contact lenses: the NaturalVue Enhanced Multifocal and the MiSight lenses. Participants aged 9 to 30 years with myopia will be assessed on various visual metrics, including acuity, contrast sensitivity, and dynamic vision. The study will involve wearing the assigned lenses and attending follow-up visits to monitor performance and comfort. The goal is to determine which lens provides better visual outcomes for users.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Participants must satisfy the following conditions for inclusion in the trial:

  * Be between 9 and 30 years of age
  * Sign written Informed Consent/Assent.
  * Spherical Equivalent glasses prescription: -0.50 to -7.00 diopters (D), Astigmatism: ≤ -0.75D, Anisometropia: ≤ 1.00D
  * 20/20 vision in each eye
  * Existing contact lens wearer
  * An eye exam in last 9 months, normal stereoacuity on prior chart (or test if not available)
  * No known ocular disease - anterior or posterior (posterior determined by history/chart)
  * Have an acceptable or optimal fit with test lenses and be willing to wear these lenses as directed for the duration of the study.
  * On examination, have ocular findings considered to be within normal limits.
  * Be willing and able to follow instructions and attend the schedule of follow-up visits.

Exclusion Criteria:

* Any of the following will exclude a participant from this trial:

  * Current hard lens wearers
  * Using eye medication contraindicating lens wear such as daily use of artificial tears.
  * Eye injury or surgery within twelve weeks immediately prior to enrollment for this trial.
  * History of corneal refractive surgery
  * Currently enrolled in an ophthalmic clinical trial that could negatively impact corneal or conjunctival health in this trial.
  * Evidence of systemic or ocular abnormality, infection or disease likely to affect successful wear of contact lenses or use of their accessory solutions.
  * Allergy or sensitivity to any product used in this trial.
  * Pre-existing ocular condition that would contraindicate lens wear.
  * Any systemic disease including autoimmune disease, immunocompromising diseases, connective tissue disease, clinically significant atopic diseases, insulin dependent diabetes, use of medications including corticosteroids and antimetabolites that may affect the eye or be exaggerated by wearing contact lenses.
  * Lazy eye (Strabismus or amblyopia)
  * Pupil size \< 3.00 mm in either eye in dim light (measured at approximately 10 cd/m2 )
