Silicone hydrogel contact lenses popular among extended wear users
By Alexa Kaczka
The majority of people who opt for extended wear contact lenses
choose the silicone hydrogel type, which allow more air to get to the eyes.
Research published in the journal Optometry and Vision Science found that 72 per cent of extended wear lenses purchased were of this type.
Many eye care professionals consider silicone hydrogel lenses to be the best option, as they allow significantly more oxygen to reach the front surface of the eye than the standard soft lenses.
It was also found that most people who use extended wear contact lenses purchased contact lens
solutions alongside the eyewear.
This indicates that a lot of wearers may remove their lenses occasionally rather than sleeping with them in continuously for as long as they last.
While extended wear contacts can be left in overnight, Dr Shahzad Mian, a cornea specialist at the University of Michigan's Kellogg Eye Center, has advised that even people with these type of lenses should remove them before bed.
