Efficacy of Multi-Type Photolithography Flat Microstructure Lenses for Childhood Myopia Control

N/A NCT07535658 Kind: NA Apr 17, 2026

Abstract

The goal of this clinical trial is to learn if photolithographic flat microstructure lenses work to prevent myopia in children. It will also learn about the safety of different designs of photolithographic flat microstructure lenses. The main questions it aims to answer are:

Are photolithography flat microstructure lenses effective and safe in preventing myopia in children? Does the depth of tinted lenses affect visual quality? Researchers will compare photolithography flat microstructure lenses to a spectacle lenses with aspherical lenslets to see if photolithography flat microstructure lenses works to prevent myopia in children.

Participants will:

Wear photolithography flat microstructure lenses or Spectacle Lenses with Aspherical Lenslets more than 8H per day for 1 year.

Visit the clinic once every 3 months for checkups and tests.

Conditions: Myopia

Interventions: wearing photolithography plano microstructure lenses with multi-point defocus design, non-fading optical property, wearing Plano microstructure lenses featuring multi-point defocus design with aspherical lenslets (Essilor Stellest), wearing Photolithography Plano Microstructure Lenses incorporates a multi-point defocus optical architecture , featuring photochromic properties with a light transmittance of 55% post-activation, wearing Photolithography Plano Microstructure Lenses incorporates a multi-point defocus optical architecture , featuring photochromic properties with a light transmittance of 35% post-activation, wearing Photolithography Plano Microstructure Lenses designed to reduce contrast sensitivity and featuring a non-fading optical property
