A guide to hard contact lenses



A guide to hard contact lenses

Wearing contact lenses can be much more liberating than wearing a pair of glasses, and they’re more convenient.
What are the advantages of hard contact lenses?
Unfortunately, many people cannot use soft contact lenses, the most popular kind of disposable lenses, for a variety of reasons.
In  this case, it might be possible to use hard contact lenses. These  lenses may take some time to get used to and require a little more care  than soft lenses, but they are still an option for many people.  

%%% When most people hear the term “hard lenses” or even “rigid lenses,”  they tend to think about the old lenses constructed of plastic.
Today, the term usually refers to permanent rigid contact lenses, often called RGP (rigid gas permeable) lenses.

These lenses are softer than the old lenses and have several advantages over soft contact lenses.
Some of these advantages include: better visual acuity, more oxygen to the eyes, and they can be used as astigmatism contacts.
There  are, of course, a few disadvantages. RGP lenses take a little more time  getting used to. In fact, you may need to wear your RGP lenses for up  to two days before your eyes adjust enough to make wearing them  comfortable.
Your vision may also be blurry when you first remove your contact lenses. This may last for several hours.
These  lenses also have to be cleaned every night, not simply thrown away.  With proper cleaning, RGP lenses can last for years and are designed to  be extended wear lenses.

Cleaning hard contact lenses

Cleaning
To cleanse your contact lenses, first scrub your hands.

Plug the drain of the sink to prevent washing a lens away.

Put one lens into the palm of your hand. Put a couple of drops of hard contact solution onto the lens.
Rub this in a circular motion for about 20 seconds to remove any dirt or protein deposits.

Rinse with a saline solution and place in a contact lens case. Fill the  case with saline solution or a hard contact lenses conditioning  solution, but not the cleaner.
Repeat with the second lens. When you’re ready to put your lenses in again, rinse with a bit of fresh saline solution first.

Final word
This  will keep them fresh and help your eyes adapt to the much faster.  Contact lens care for hard contact lenses may be a little more effort,  but it is worth the time when you consider how long the lenses will  last.
