Primarily because soft lenses are instantly comfortable, and GP lenses require an adaptation period before they are as comfortable as soft contacts. Gas permeable contact lenses offer some outstanding benefits over soft lenses.
For one, because GP lenses are made from a firm plastic material, they retain their shape when you blink, which tends to provide sharper vision than pliable soft lenses. GP lenses also are extremely durable. Although you can break them for instance, if you step on them , you can't tear them easily, like soft lenses. And they're made of materials that don't contain water as soft contact lenses do , so organic materials protein and lipids from your tears do not adhere to GP lenses as readily as they do to soft lenses.
With a little care, gas permeable contact lenses can last for years, as long as you don't require a lens prescription change. Though they are less popular than soft lenses, gas permeable contacts are the best choice for many individuals, including:.
People who are very discerning and are willing to go through a period of adaptation to contact lens wear to achieve the sharpest vision possible. Some people with astigmatism for whom soft contacts don't produce the desired visual acuity. People with presbyopia , because GP lenses come in numerous bifocal and multifocal designs. Different bifocal designs work well for different people, so having many choices is a real plus.
Gas permeable lenses are known to slip off the center of your eye. This usually lasts for mere seconds, but when it happens multiple times throughout the day, it can become irritating very quickly. You know that feeling when something is stuck in your eye? This can happen with GP lenses. Tiny pieces of debris can get lodged underneath the lenses, causing pain or discomfort.
Scleral lenses usually last for up to 3 years, but as with all types of contact lenses, make sure you use the lens case, contact solution, and any other materials as instructed by your eye doctor. This will make sure you enjoy continued clear, comfortable vision and make your lenses last longer.
Not surprisingly, according to Dr. Jacqueline Cozzone, it is ill advised to do so. Wearing contacts overnight prevents oxygen from entering the cornea and can increase the risk of developing corneal infections or ulcers.
Always take them out before going to sleep, clean and store them safely. Only sleep in scleral lenses if specifically instructed to by your doctor. This is when tiny debris cause the lenses to fog up. We favor rigid gas permeable lenses over soft lenses for the following cases: For those who want the sharpest vision possible.
Those with presbyopia. There are many bifocal and multifocal lens designs. Those affected by keratoconus where the cornea is cone-shaped and causes a lot of visual distortion. Most of the time, in this case, rigid contact lenses are a long term treatment. Because this is a disease that progresses, it is important for these lenses to be fitted with care and checked annually by a contact lens specialist.
