Types of Eye Contact Lenses

An Eye Contact Lens is an eyeglass device that is worn to improve vision. These lenses can correct a variety of vision problems, including astigmatism. Some of the types include colour tint lenses, gas-permeable lenses, and hybrid lenses. Hybrid lenses offer crisp optics to a distorted cornea.

Colour tint lenses change the color of your eyes

Coloured contact lenses are lenses that change the color of your eyes. The lenses imitate the natural patterning and texture of the iris, but leave the center of the eye clear. These lenses come in many different shades and can be used for different purposes. They can change the color of your eyes to make them look blue, green, or even brown.

Wearing contact lenses is the most convenient way to change your eye colour temporarily. The process is fast and easy, and you can change the color of your eyes in minutes. Opaque-tint lenses change your eye color completely, but are best for people with dark-colored eyes or those who want dramatic eye color changes.

Scleral lenses correct corneal irregularities

Scleral lenses are a treatment option for patients suffering from corneal irregularities. These lenses correct irregularities in the cornea without damaging the eye’s natural lubrication. They also help patients suffering from dry eye syndrome because they don’t lose moisture when removed. Instead, scleral lenses hold the liquid in place to keep the surface of the eye moist. In contrast, corneal GP lenses can sharpen vision and cause lens expulsion or decentration, as well as trapping debris in the cornea.

Many people experience corneal irregularities, which can cause vision problems. In some cases, the irregularities occur due to a condition called keratoconus. If the cornea is too thick or too thin, light can’t bend properly and cause distorted vision. In other cases, the irregularity may be caused by a foreign substance that resides in the eye. Another condition that affects the cornea is dry eye, which impairs tear production.

Gas-permeable lenses cause allergies

Gas-permeable eye contact lenses, or GPC, can cause allergies in some people. The preservatives in the solutions used to make the contact lenses can remain in the eye after cleaning. These preservatives can irritate your eye and cause an allergic reaction. These reactions can occur at any time – even months or years after you first started wearing contact lenses. Many people experience these reactions with no previous history of allergies. To determine if your contacts are causing allergies, consult with  Prairie Eye Contact Lens Exams Edmonton  your eye care provider. They will ask you questions about your symptoms and examine your eyes.

Symptoms of an allergy may include a burning sensation in the eye or extra sensitivity to light. A doctor can determine the cause of the allergy, and prescribe an appropriate treatment. Sometimes, the allergy is harmless and will clear up on its own. Regardless of the cause, it is best to avoid wearing contact lenses if your eyes are irritated.

Hybrid lenses provide crisp optics to a distorted cornea

Hybrid lenses are a relatively new solution for distorted corneas. These lenses combine a rigid center with a soft peripheral area to provide crisp optics. These lenses are also more comfortable to wear, because the soft skirt holds the rigid center in place. Hybrid lenses are suitable for most patients, but some patients may not benefit from the technology.

Developed specifically for keratoconus patients, hybrid contact lenses provide crisp optics in addition to comfort and convenience. Different brands offer a variety of designs that conform to the irregular shape of keratoconic corneas. The fit of these lenses is also highly customizable. The larger diameter gas permeable lenses cover a larger portion of the sclera than conventional contacts, and do not exert as much pressure on the cornea.

Orthokeratology uses hard contact lenses to change the shape of the cornea

Orthokeratology is a nonsurgical procedure for correcting refractive errors. It involves using hard contact lenses to alter the shape of the cornea. In the early days of ortho-k, hard lenses were the only material available. Patients had to wear a series of lenses for several months to achieve the desired effect. Today, advances in technology have allowed for accelerated ortho-k. The newer methods and materials can produce results in as little as a few days.

The process is not without risk. It can lead to corneal swelling and infections. It can also damage the cornea if worn for long periods. However, the risks are minimal, and wearing the lenses correctly will minimize the risk. The risks are similar to those associated with regular use of standard soft contact lenses.
