Progressive lenses are lenses which incorporate multiple powers of vision (such as close up, or far away distance) into one single lens. Unlike bifocals, which are split, a progressive lens contains one continuous, smooth lens without a dividing line. The lenses power changes progressively from distance to near vision. They are basically bifocal or trifocal lenses, but without the dividing line. They are ideal for patients who have presbyopia, a vision condition which makes it hard to focus on close up objects. This happens to many people over time as they age. Both objects near and far become harder to see sharply and focus on.
In progressive lenses, the distance field is usually built into the upper portion of the lens while the near vision is built into the lower part of the lens. The lens is blended together, while the middle portion usually contains the intermediate vision correction. The intermediate vision section is good for those who work with computers. Progressive lenses are popular with people because of their ability to look like normal, single vision eyeglasses. Most adults who reach a certain age will need both reading and distance correction at some point in their lives.
Bifocal lenses are made with two powers of vision within the lens and divided by a horizontal line across the lens’s surface. The top of the bifocal lens is used for distance vision and the bottom is used for near vision. Presbyopia is a condition that happens to adults as they age, and bifocals or trifocals are normally used to help patients see clearly at all distances. Whereas bifocals contain two lens powers, trifocals contain three. Most people over the age of 40 begin to use multi-focal lenses, or children who have eye focusing problems or eye strain. In bifocals, the bottom half of the lens reduces the amount of focusing effort needed to see near objects. All bifocals work the same way, in that the smaller portion of the lens corrects near vision while the rest of the lens handles the distance vision. The wearer usually looks down through the segmented bottom half when reading, and upwards when looking at distant objects. Bifocals can be distracting for some, such as those who play sports.
Single vision lenses are lenses in which there is only one power, such as near distance, or far distance. These are ideal for people who only need one type of vision correction. For example, someone who is nearsighted, or able to see objects close up, may need glasses for distance. And vice versa for those who can see far away objects, but not close up. Single vision lenses can come with various coatings and tints to help reduce glare, scratching and other things that can affect the lens and help them last longer. Single vision lenses can be fitted into various types of frames, and can be adjusted as needed as prescriptions change.
Lens materials are classified by the different types of materials used to create eyeglass lenses. Lenses are categorized by their refractive index, or the speed that light travels in a vacuum vs the speed of light in the material of the lens. The refractive index of a basic plastic lens is known as CR-39. A high index of refraction means the lens material can be thinner. Standard lenses are CR-39 lenses and are made with conventional plastic materials. They are affordable, provide clear optical vision and are easy to tint and wear.
Polycarbonate lenses are a higher index of lens and thinner, bending light in a more efficient manner, therefore requiring less material. Polycarbonate lenses are impact resistant, block UV rays and offer up to 10 times more resistance to impact than regular plastic lenses do
Trivex lenses are a newer type of optical lens material. Trivex lenses block UV rays and are shatter resistant. They provide superior optical clarity with little in the way of chromatic aberrations. They work well in rimless frames.
High index lenses are the thinnest lenses available. They work well for those who have high optical prescriptions but can work for anyone looking for a thinner lens. They are more expensive than regular materials, however, making them one of the more expensive types of glasses.
Anti-reflective coatings are special coatings that are usually applied to both sides of lenses to reduce glare from car headlights at night and computers. This allows good light to enter the eye so that the clearest vision is achieved. Light that hits eyeglass lenses is reflected off the lens and causes a glare as it reflects off it. Oncoming cars can produce glare while driving, and flare from street lamps. It is difficult to see clearly when the glare is oncoming as the eyes begin to try and filter out the noise from the reflections and glare. Lens coatings work by absorbing reflected light and bending it to get rid of the glare. Those with astigmatism and high prescription lenses benefit greatly from anti-reflective coatings. Glasses should be kept in their case when not in use. Microfiber cloth should be used to clean them with water or solution.
Transitions photochromic lenses are a great new way to enjoy both sunglasses and corrective lenses in one pair. Transitions lenses are clear indoors, and then darken when the wearer goes into sunlight outdoors. Transitions come in prescription and non-prescription and allow wearers to have the best of both worlds. They are ideal for people who need glasses indoors but who do not want to switch to sunglasses when going outdoors. Some people cannot wear contact lenses, making Transitions lenses ideal for them so that they only need one pair of glasses. Transitions can be made for all different kinds of prescriptions. Transitions are a good alternative to prescription sunglasses because they contain everything needed in one pair of lens, making the chances of them getting lost less as the wearer only needs to have one pair instead of two.
Polarized lenses reduce glare from surfaces such as water, snow, and glass. Those who work outdoors use polarized lenses, because they reduce glare enough to perform outdoor functions. Boaters, skiers, golfers and bikers especially use polarized lenses, which works by polarizing the light and reducing it. Those who fish use polarized lenses to reduce the blinding effect of the water and help to see things under the water’s surface. They are also good for driving and for those who may have had cataract surgery and need less light coming in until their eyes heal.
Regular eye exams are an invaluable tool in maintaining healthy eyes by detecting and preventing disease. Some diseases develop slowly without causing pain or vision loss. Early detection of any problems can reduce the risk of further harm and allow for a choice of treatment options. Part of your exam includes the following procedures: Slit Lamp Examinations, Dilated Eye Exams, Refraction for Glasses and Contact Lenses and Glaucoma Pressure Testing as well as a series of computerized tests to determine the health of your eyes.
Thanks to the advances in optical technology, almost everyone is a candidate for contact lens use. This includes patients with astigmatism and also those who prefer bifocal or multifocal lenses. On site ophthalmologists and optometrist offer a comprehensive array of contact lenses to suit each individual patient's needs. We offer daily disposables, extended wear soft lenses and gas permeable contact lenses.
Macular degeneration is a chronic eye disease that can severely impact vision. The most common type is called dry macular degeneration. The less common wet form is more severe and can be very disabling. Today, through early detection and treatment, eye care professionals are better able to manage this disease.
Glaucoma, the leading cause of blindness and visual impairment, is an eye disease that can lead to a permanent loss of vision. On site eye care professionals provide all diagnostic and treatment options for glaucoma care. Glaucoma generally provides no warning signs or symptoms of disease, making testing an important part of a full vision exam.
