Summary

This trial compares two types of contact lenses to see which one works better for vision.

Who is the study for?
This trial is for near-sighted children and teenagers aged 8 to 18 who regularly wear soft contact lenses for distance vision. They must have a prescription between -0.75D to -7.00D, with astigmatism ≤ -0.75D in each eye, and be able to see clearly with corrective lenses. Participants need wearable backup glasses and can't have worn rigid or ortho-keratology lenses recently, nor can they sleep in their lenses or be on atropine treatment.
What is being tested?
The study aims to compare the performance of two types of daily disposable contact lenses: an investigational silicone hydrogel lens (test) versus a commercially available hydrogel lens (control). Participants will switch between the test and control lenses over one week to assess visual quality.
What are the potential side effects?
Potential side effects from wearing contact lenses typically include discomfort, dry eyes, redness, blurry vision, tearing up, or infection risk if not used properly.
