Contact lenses are very thin discs of plastic placed directly on the eye to correct vision problems such as astigmatism, farsightedness, presbyopia, and nearsightedness. There are various types of contact lenses, and it is important to get ones that fit the size and shape of your eyes even as they correct your vision. Contact lenses in Chevy Chase, MD, are designed to correct individual eye problems and suit different lifestyles.
There are two types of contact lenses; soft and hard contact lenses.
These are made from a special type of soft plastic which makes them mold easily and water. The water allows oxygen to pass through the lens to your cornea, therefore, making it comfortable and healthy. These eye contacts material can absorb chemicals, particles, and bacteria. Some types of soft contacts are worn for just a day then disposed of. They are called daily disposables and are suitable for people with allergies. You may choose colored contacts which play up your natural eye color, giving you a hip look.
They are stiff eye contact lenses made from silicone. They are stiff but allow oxygen to pass through to the cornea. Rigid gas-permeable contacts are durable and easy to take care of.
These contact lenses are designed for individuals who suffer from astigmatism. The vision of a person who suffers from astigmatism is blurred at any distance since the cornea of their eye has an irregular shape. This condition is known as corneal astigmatism. Lenticular astigmatism occurs when the lens of your eyes is misshapen.
Blurred and distorted vision caused by this eye condition can be corrected by using special contact lenses designed to address the problem. Toric contact lenses are prescribed for people with mild and moderate astigmatism to help bring their vision into focus. In addition, rigid gas permeable contacts are used to reshape the eye.
The shape of the toric lens creates different focusing or refractive powers that help correct astigmatism. These eye lenses have a thicker zone that prevents them from rotating when they are in the eyes. They achieve an exact fit in the eyes since they contain a middle axis that keeps your line of vision clear and improves visual acuity. Toric contact lenses in Chevy Chase, MD, come in various types and fits suitable for different people.
Orthokeratology uses specially designed and fitted contact lenses to temporarily reshape the cornea to improve vision. Your ophthalmologist will use a special instrument to map, measure and design these eye lenses. The lenses correct eye problems by flattening the center of the cornea and changing how light is bent as it enters your eye.
These rigid gas permeable contact lenses are worn at night to gently reshape the eye’s cornea or the front surface. They enable the wearer to see clearly the following day or two after using them at night. Orthokeratology lenses temporarily correct nearsightedness, lesser degrees of astigmatism, presbyopia, and farsightedness.
Monovision lenses are for correcting vision problems in one eye. For example, one eye may have a contact lens prescribed for farsightedness, while the other will be for seeing up close.
Bifocal contacts are made of either soft or gas-permeable material. They help your eyes regain the ability to focus from near or far. These contact lenses correct both far and near vision as they have both distance prescription and near prescription in one lens.
Taking good care of your contact lenses extends their life and keeps your eyes healthy and safe.
