Our ophthalmologists and opticians are skilled at guiding you towards decisions regarding glasses and contact lenses. We can help you with fitting lenses, or choosing from a variety of brands and styles of glasses. You may purchase glasses or contact lenses at our optical shop in Bethpage.
If you are interested in learning more about glasses or contact lenses, please call 516.731.4800 or 516.358.2300 to make an appointment.
A refractive error is an error in the focusing of light by the eye and a frequent cause of decreased vision. There are various types of refractive errors that can occur alone or in conjunction with one another.
Myopia (nearsightedness) results when light rays focus in front of the retina. Usually this occurs in an eye that is longer than average. This results in vision that is clearer at near than at distance.
Hyperopia (farsightedness) results when light rays focus behind the retina. Usually this occurs in an eye that is shorter than average. This results in vision that is clearer at distance than at near.
Astigmatism is a common condition that can occur with myopia or hyperopia. Astigmatism occurs when the cornea is not round like a basketball but is shaped like a football. A cornea with astigmatism is steep in one direction and flat in the opposing direction.
Presbyopia is the tendency for near vision to decrease as we age. Presbyopia occurs when the lens inside the eye cannot focus on near objects. Presbyopia usually affects people in their mid-forties, however, it can begin earlier in life in people with hyperopia (farsightedness) and later in life in people with myopia (nearsightedness).
Over your lifetime, vision can change. When light rays enter the eye through the cornea, they focus in the back of the eye onto the retina. If they do not focus perfectly on the retina, we say that a patient has refractive error. Refractive error can be corrected with glasses, contact lenses or refractive surgery such as LASIK . Our expertly trained physicians will examine your eyes to determine if you have refractive error that requires correction through a process known as refraction. We are proud to carry a large variety of men's and women's glasses as well as contact lenses in our Bethpage optical shop.
If you need correction for your vision, you may consider contact lenses as a preferable alternative to spectacles. Contact lenses sit on the front part of the eye called the cornea. With the newer generation of silicone lenses, we are able to fit most people in contact lenses. With today's newer technology, mature individuals can see both at distance and near with a "bifocal" contact lens. As an alternative, we still fit patients in traditional hydrogel lenses and rigid gas permeable lenses when necessary. The replacement schedule for contacts can be as short as one day or as long as a year. The best type of lens is determined on individual basis based on a complete eye exam and consultation with one of our physicians.
