Opt for dry eyes?

OPT is

a non-pharmaceutical treatment that improves the optical quality of the eye surface by using special optical instruments and changes the focus of light so that it falls more accurately on the retina, thereby improving visual effects and comfort. Patients with dry eye are often accompanied by unstable tear film, resulting in abnormal scattering or refraction of light when passing through the cornea, affecting vision. OPT can be performed with the help of a professional doctor to promote recovery
