Contact lenses are prosthetic lenses used to correct vision disorders and placed on the surface of the cornea. Soft lenses are typically made from hydrogel or silicone hydrogel materials and conform to the eye surface. These lenses are commonly used to correct many vision defects such as myopia, hyperopia, astigmatism, and presbyopia.

Soft lenses provide clear vision by altering the refractive power of the eye due to their flexibility. Additionally, they offer comfortable wear by better accommodating eyelid and eye movements. These features make soft lenses suitable for daily comfortable use.

These lenses are also designed to increase oxygen intake in the eye, supporting long-term use while preserving eye health. However, users should pay attention to the cleanliness and maintenance of the lenses as non-compliance with hygiene rules can increase the risk of infection.
