Prescription eyeglasses are much more than simple fashion statements; they are important pieces of technology that can greatly improve quality of life. This is why it is important for individuals to pay visits to an optometrist in Indianapolis to make sure that these indispensable tools are available to all that need them. When patients make the trip to the optometrist, the physician will be checking for four commonly seen eye conditions.
Commonly Diagnosed Conditions
Myopia. Also known as nearsightedness, this disorder can make far away objects seem to be blurred, but objects that are nearby very clear. Medicated glasses use special lenses that correct this refraction error.
Hyperopia. Also known as farsightedness, this eye condition allows far away objects to be clearly seen, but presents complications with nearby objects.
Astigmatism. This condition is caused by uneven curvature of certain surfaces within the eye. Because of this, rays of light are unable to come to a single focal point within the eye. This condition can appear at the same time as farsightedness or nearsightedness.
Presbyopia. If the eye eventually loses its flexibility and is unable to change shape in order to focus, presbyopia is usually the diagnosis. This condition is typically experienced by people over the age of 40, and often necessitates reading glasses.
What Kinds of Lenses Are Available?
A surprisingly large variety of eyeglass options are available. The following will give readers an example of the extent of this.
Multifocal and bifocal lenses. Bifocals as well as trifocals are available in quite a few configurations and sizes. One of the great benefits of using trifocals and bifocals is that they allow individuals to see objects at varying distances without having to constantly remove the glasses.
This effort is assisted if patients are sure to communicate to their eye doctors the distances they typically use for focus. Individuals interested in this capability will want to consider making use of progressive lenses. These high tech additions to the family can focus to almost 20 distances with a very smooth transition from the bottom to the center.
Specialized eye glass lens coatings. Special coatings are available for the specific needs that each person brings to the table. Included in this category are scratch resistant coatings, anti-reflection coatings, anti-fog coatings, and anti-UV coatings. These options can enhance vision and increase the lifespan of the eyeglasses.
Eyeglass technology is certainly a thing to behold. Residents that buy eyeglasses in Indianapolis will be doing themselves a big favor by availing themselves of these futuristic and amazing offerings.
