Eye glasses

Vision improvement products & advice


Here you can find eye glasses to make seeing easier, such as reading glasses and contact lenses including disposable contact lenses. Also very useful resources giving expert information and advice to improve eyesight.

People are often 'conditioned' to expect a reduction in their vision. If the sight fails, because this natural decay has been observed for so long, there can be acceptance rather than a conviction that things might be better. There is much up to date information available about what can be done to improve vision. Elderly people can benefit from contact lenses and eye glasses as well as operations to improve vision.

Lenses for correcting or improving vision:
There are two types of lenses prescribed for correcting or improving vision. These include:

· eyeglasses (Also called spectacles.)
Eyeglasses, the most common form of eyewear used to correct or improve many types of vision problems, are a frame that holds two pieces of glass or plastic, which have been ground into lenses to correct refractive errors. Refractive errors can include nearsightedness or myopia (difficulty seeing far away), farsightedness or hyperopia (difficulty seeing close up), and astigmatism (blurring due to an irregularly shaped cornea). Eyeglasses perform this function by adding or subtracting focusing power to the eye's cornea and lens.

· contact lenses
Contact lenses are worn directly on the cornea of the eye. Like eyeglasses, contact lenses help to correct refractive errors and perform this function by adding or subtracting focusing power to the eye's cornea and lens.
How to read an eyeglass prescription:
The lens power of eyeglasses is measured in diopters. This measurement reflects the amount of power necessary to focus images directly on to the retina. When looking at an eyeglass prescription, you will see the following abbreviations:
O.D. - Oculus dextrus simply refers to the right eye (sometimes the abbreviation RE is used).
O.S. - Oculus sinister refers to the left eye (sometimes the abbreviation LE is used).

In addition, the eyeglass prescription may also contain the following measurements:
· sphere - this number measurement reflects the extent of the nearsightedness or farsightedness.

· cylinder - this number measurement refers to the amount of astigmatism (an irregularly shaped cornea which causes blurring) in the eye.

· axis - this number measurement describes the direction of the astigmatism in degrees. Bifocal is additional power in the lens and has an additional measurement listed on the prescription as "add," to indicate the strength of the lens.

What are the different types of eyeglass lenses?

The type of lenses used in eyeglasses depends on the type of vision problem, and may include:
· concave lenses - are thinnest in the center. Used to correct nearsightedness (myopia), the numerical prescription in diopters is always marked with a minus (-) symbol.

· convex lenses - are thickest in the center, like a magnifying glass. Used to correct farsightedness (hyperopia), the numerical prescription in diopters is always marked with a plus (+) symbol.

· cylindrical lenses - curve more in one direction than in the other and are often used to correct astigmatism.

Facts about contact lenses:
Many people wear contact lenses, half of whom wear daily wear soft lenses. Currently, there are five types of contact lenses in use, including the following:
· the original "hard" lens
· the rigid, gas-permeable lens
· other rigid lenses
· the soft, water-absorbing lens
· other flexible, non-water absorbing lenses
Reading a contact lens prescription:
The prescription for contact lenses includes more information than what is available on the prescription for eyeglasses. Special measurements are taken of the curvature of the eye. In addition your optician will determine if the eyes are too dry for contact lenses, and if there are any corneal problems that may prevent a person from wearing contact lenses. Trial lenses are usually tested on the eyes for a period of time to ensure proper fit.
The contact lens prescription usually includes the following information:
· contact lens power (measured in diopters, like eyeglasses)
· contact lens base curve
· diameter of the lens
Eye care specialists are required to give you a copy of your contact lens specifications.
