RGP contact lenses,rigid gas permeable contact lensesOpinions on RGP Contact LensesOne of the most vital factors in eye health is continual exposure to air. Oxygen helps keep all tissues healthy and the eyes are no exception. But all contacts cut back the oxygen that contacts the eyes rather, some more than others. During the past, that 'somewhat' was important. Air migrated into the tear solution when the lens moved a little during blinking. That helps keep eyes washed with oxygen to degrade protein buildup, micro-organisms and other stuff that would increase the chances of infection or other eye issues. RGP lenses are midway between a soft lens and a tough lens. That gives them a good balance of comfort whilst providing enough rigidity to fix mild cases of astigmatism, which soft lenses can't do. For other cases of astigmatism, toric lenses are available in an RGP style. That firmness makes them helpful for correcting mild cases of corneal warpage too. Other out-of-shape conditions, like keratoconus, an illness in which the cornea becomes rather cone formed, reply better to RGP lenses, too. Since they are firmer, they keep their shape better when blinking and during standard movement. Reviews on RGP contact lensesRGP lenses are flexible enough to move with it, making for a good fit and extremely pointy optics. That same firmness makes them better suited to making bifocal lenses than a soft contact lens, too. RGP contacts also have a tendency to go on longer than soft lenses. The characteristic RGP lens will last more than a year before requiring replacement. They are made from sturdy material that is not as likely to rip or scratch than soft contact lenses. One effect of the material is they don't draw moisture from the eye. That makes them cosy to wear, after a preliminary adjustment period. Soft lenses, whilst snug straight away, absorb tear solution from the eye, causing the eye to dry out rather more after some hours of wear. And as they are highly oxygen permeable RGP lenses can be worn for longer periods with less chance of protein or bacteria buildup. Also, as they resist protein buildup better than other types, they are simpler to keep clean and sterile. RGP lenses do need a touch different kind of cleaning solution, though, so be certain to get the right kind when ordering this style. But if your eye care professional commends them, you're certain to find they suit you well. You can read more about Gas Permeable Contacts here. Go from RGP contact lenses to About Contact Lenses |
