For millions, contact lenses provide a safe and effective alternative to eyeglasses. Like the proper fit of shoes, contacts must be expertly fitted for cornea health and comfort with a Contact Lens Exam at one of our 5 Vision Center locations in Long Island. It’s important to remember: one contact lens size doesn’t fit all, which is why you should visit your Long Island eye doctor for a proper examination and fitting. If the curvature of a contact lens is too flat or too steep for your eye’s shape, you could experience corneal discomfort or even eye damage.
During an eye exam fitting at a Long Island Vision Center, you will be asked general questions about your lifestyle and preferences regarding contact lenses, such as whether you’re involved in sports or if you’re interested in options such as daily disposable lenses or overnight (extended) wear. Your Greenlawn eye doctor may also discuss the option of rigid gas permeable (RGP or GP) contact lenses. Although most people today are fitted with soft lenses, some patients with high amounts of astigmatism or other irregular corneal conditions benefit from the high degree of vision correction offered by GP lenses.
Your eye doctor may ask you about how you might want to correct vision problems related to aging. At about age 40 or maybe older, you may develop a condition known as presbyopia that decreases your ability to see clearly at close distances. To correct presbyopia, your eye doctor at Moriches Vision Center may offer you the choice of multifocal or bifocal contact lenses or monovision. With monovision one contact lens corrects for near vision and the other contact lens corrects for distance vision.
To fit your contacts, the doctor or contact lens technician will use an instrument called a keratometer to measure the curvature of your eye’s clear front surface called the cornea. These measurements or K-readings help your eye professional determine the proper curve and size for your contact lenses. Some types of contact lens fitting require that your Whitestone eye doctor knows the size of your pupils in different lighting conditions as well as the diameter of your cornea. Pupil and iris measurements help achieve a proper sizing and orientation of your contact lens.
For the last part of your Long Island contact lens exam, the health of your cornea will be evaluated using a biomicroscope or slit lamp. This information is critical for determining the type of contact lens & wear schedule, as well as establish a baseline for your doctor to evaluate any future changes to your eyes related to contact lens wear.
