Lens scratches, if minor, generally do not affect the patient’s vision, but if they are severe, they may affect the patient’s vision.
Superficial, minor lens scratches have a small effect on the refractive index and transmittance of light, and therefore do not affect the wearing effect and will not impair the patient’s vision. If the scratches are severe, they will affect the optical properties of the lenses, which can affect the refractive index of the lenses and fail to correct the refractive error properly, which may lead to a decrease in the patient’s vision.
More severe lens scratches not only affect the patient’s vision, but may also cause the patient to be prone to visual fatigue, and may even cause the patient’s refractive error to worsen.
It is recommended that patients with obvious scratches in their lenses should consult a regular hospital in a timely manner and have their lenses replaced under the guidance of a doctor, and should not blindly wear scratched lenses to avoid adverse effects on their vision.
