Which polish is most suitable for adjusting or polishing GP lenses?

When adjusting or polishing gas permeable (GP) lenses, the most suitable option is a water-soluble polish. This type of polish is specifically formulated to work effectively with the materials used in GP lenses, ensuring that the polishing process does not damage or compromise the integrity of the lens.

Water-soluble polish can effectively remove minor scratches and surface imperfections while minimizing the risk of causing additional damage through excessive abrasion or chemical reactions that may occur with other types of polishes. Additionally, since GP lenses have specific surface properties, using a polish that is compatible with these materials is crucial for maintaining lens clarity and performance.

In contrast, ammonia-based polish can be too harsh for GP lenses, potentially leading to damaging effects on their surface. Sodium bicarbonate polish may not have the necessary properties for effective polishing of lens materials, and solvent-based polish poses a risk of damaging the lens material due to chemical interaction. Therefore, water-soluble polish emerges as the best choice for achieving a smooth and clear surface on GP lenses without adverse effects.
