Wearing a pair of glasses can be fun for some people who like to go with a trendy hipster look or prefer to wear something less irritating to put on than contact lenses. Eye contacts may have acquired a nasty reputation as itchy and uncomfortable to wear. On the contrary, this doesn’t have to be true for everyone as long as the individual’s choice of corneal prosthesis fits his or her needs to keep a twenty-twenty vision intact. These questions and their corresponding answers should provide some enlightening information into the use of contact lenses designed to change the shape of a person’s cornea.
How can contact lenses change the shape of the cornea?
These lenses must be worn before bedtime instead of in the morning before going to work or to school. Instead of wearing contacts all day, the patient is advised to wear them at night – something doctors and experienced users know is a definite no-no in contact lenses. However, because of the pressure the eyes put on the lenses, the curvature at their back also puts pressure onto the corneal surface. A tear-film between the cornea and the lenses protects the eyes from injury.
How comfortable are these reverse contact lenses?
Because these corneal lenses are worn at night, there’s the little sensation of foreign objects inside the eyes while blinking. The rapid eye movements during sleep won’t affect the position of the lenses on the corneal surface. Moreover, patients are assured that after at least six hours of sleep up to 70% of improvement in their eyesight is experienced. After the third night of use, daytime vision becomes clearer and brighter for some people.
How safe are these nighttime contact lenses?
The comfort and safety of using these special lenses depend on the correct fit of the contacts over the patient’s eyes. They’re made from high oxygen permeable materials that must be kept clean at all times to prevent infection. After a year and a half and up to two years, the lenses must be replaced.
Can children use these unique contact lenses?
Actually, children’s eyes are the best candidate for these lenses because their eyesight is still developing as they grow older. These reverse contacts often slow down the progression of myopia in children. What’s more, children who didn’t have to wear glasses to correct their eyesight can participate in more activities for fun and sports than before. There are also fewer incidents of eye irritation or lost contact.
Most adults and children who use these reverse contacts can use them at night because the front area is equipped with corrective lenses that can help nearsighted or farsighted patients see better in a dim environment. Finally, people with a severe dry eye problem should consult their optometrist first before trying on a pair of reverse contact lenses at night.
