Hanita Lenses' Intensity lens is known as a pentafocal (five-focus) lens. At 6 meters, compared to a monofocal intraocular lens, it appears slightly blurry, as if foggy. As the target gets closer, it gradually becomes blurry, then appears clear from about 70 cm to about 40 cm, and becomes blurry again.
Vision through the mobile model eye
Intensity multifocal intraocular lens, day, building, pupil 3.0 mm
With Hanita Lenses' Intensity lens, distant buildings appear slightly hazy compared to a monofocal intraocular lens, as if covered in fog. This is a phenomenon typically seen in diffractive multifocal intraocular lenses.
Intensity multifocal intraocular lens, night, building, pupil 3.8 mm
With Hanita Lenses' Intensity lens, glare around bright lights at night appears more pronounced compared to a monofocal intraocular lens.

Intensity multifocal IOL, image of the eye chart by distance (pupil 3.0 mm)
The Intensity lens by Hanita Lenses is known to be a pentafocal (five-focus) lens. At 6 meters, compared with a monofocal intraocular lens, it looks slightly blurry, as if covered in fog. As the target moves closer, it gradually blurs, then appears clear from about 70 cm to about 40 cm, and then blurs again. It is difficult to clearly distinguish the five focal points.

Intensity multifocal IOL, night road, glare (pupil 3.8 mm)
This is a video actually filmed on the road at night using a portable model eye. With the Intensity lens by Hanita Lenses, compared with a monofocal intraocular lens, halos are seen around bright lights (traffic lights, vehicle headlights, taillights). This is a phenomenon typically seen with diffractive multifocal intraocular lenses. It appears more pronounced when the pupil is larger.

The specifications above are based on data provided by the IOL manufacturer or its distributor.
An IOL with a higher refractive index is thinner at the same dioptric power.
Abbe number: measured for optics exposed to air; a higher value means less chromatic aberration.
