iDefinition provides a specially selected lens design that offers greater perception of the colour green, the colour our eyes are most sensitive to in the visible light spectrum.
Green lenses provide better contrast than grey lenses and offer better colour accuracy than brown lenses. Because greens lenses favour the transmittance of green light, they provide excellent visual acuity in all light conditions. in short, this makes iDefinition perfect for modern course fishing.
As we all know accidents happen from time to time so we have now made our glasses float, giving you time to scoop them out of the water if you drop them in.
The new wide frame shape lets in less light, whilst also looking modern and stylish.

The Korum IDefinition sunglasses are okay, but not exceptional. The polarization works, but the frames feel a bit flimsy. The floating feature is the only standout.
