There is a wide range of contact lens designs and material types, each designed for a specific purpose. Here are just a few:
One-day, or single use disposable contact lenses, are the safest, most comfortable and affordable contact lenses available. They provide great vision and do not require cleaning solution which otherwise adds to your costs. You have a fresh, clean, comfortable lens everyday, and and greatly reduce the chance of infection when worn properly. These disposable contact lenses are designed to be worn for one day or a single use before disposal. They are the most successful and have the least complications. These disposable contact lenses are designed for all day use but must be removed before bedtime.
Advanced in technology allow more people than ever to wear Multifocal Contact Lens. Often, this is dependent on the wearer of the lens. Some people expect the crystal clear clarity they had in their 20's. This can sometimes be difficult to achieve and near far vision trade-offs can be involved. Multifocal contact lenses can offer users both good near and distance vision. Some offer a bifocal design with two distinct lens powers, while others have a multifocal design with a gradual change in lens power. Multifocal contacts are available in both soft and rigid gas permeable (RGP or GP).
Gas permeable contact lenses are called Rigid Gas Permeables or RGPs. They are made using a firm, durable plastic that is specifically designed to transmit oxygen. They do not contain water and therefore are not prone to deposit buildup or bacteria buildup as are other contacts. These contacts can last for much longer than soft contact lenses, provide crisper vision, and handle very easily. Gas permeable contacts are custom made and custom fitted for every individual. They provide advantages over other contacts in terms of their ease of care, ease of use, deposit resistance, clear vision and better eye health.
Rigid gas permeable lenses are often confused with hard contact lenses. These types of lenses are not the same. The confusion often results from the fact that gas permeables (RGP) are firm lenses. Hard contact lenses are no longer worn. Hard contacts presented a number of problems that are now addressed by soft and oxygen permeable lenses, such as using less firm material in manufacturing and increased oxygen transmission to the eye.
Yes, we have these too!
Specialty contact lenses are sometimes required for certain patients, particularly patients recovering from certain types of eye surgeries and patients for whom other types of contact lenses are unsuitable.
Toric contact lenses are made from the same materials as regular (“spherical”) contact lenses, so they can be either soft or rigid gas permeable (RGP). The difference is in the design of the lens. Toric lenses have two powers in them, created with curvatures at different angles (one for astigmatism, the other for either myopia or hyperopia). There’s also a mechanism to keep the contact lens relatively stable on the eye when you blink or look around. To provide crisp vision, toric contact lenses cannot rotate on your eye.
These disposable contact lenses are designed to be worn for six days without removal. While extended wear lenses seem to work perfectly for some lens wearers, the doctor does not recommend them. Especially patients who need higher levels of oxygen transmitted to the corneal surface due to illnesses like diabetes, certain medications or low tear. They also come with higher risk of infection.
These lenses are designed for use for as many as 31 consecutive days without removal. However, the doctor does not recommend them, because they are not healthy for the eye, and have increased risk of infection.
