Basically, Focus NIGHT & DAY lenses can be safely worn for 30 consecutive days without the need to clean or disinfect the lenses every day, which is very convenient and time-saving. However, the optometrist will recommend a wearing mode according to the eye health and living habits of each wearer or recommend that the wearer clean and disinfect the lenses on time.

Why can Focus NIGHT & DAY be worn for 30 days without removing it?

Whether long-wear contact lenses can be worn day and night continuously depends on many factors. But the most basic prerequisite is to be able to provide enough oxygen to the eye, that is, the lens must have sufficient oxygen permeability (Dk/t).

According to the latest research, the oxygen permeability of contact lenses must be higher than 125 to allow the wearer to sleep safely. However, if the oxygen permeability is less than 125, the most basic conditions are not met.

The oxygen permeability of Focus NIGHT & DAY is 175, which is much higher than the basic standard.

Coupled with its groundbreaking material design lotrafilcon A, it is enough to make Focus NIGHT & DAY a real long-wear soft contact lens
