Prescription GlassesMt Vernon, NY
More often than not, people find they need some form of visual aid at a certain point in life. While some people prefer contact lenses or surgery, prescription glasses are a tried and true method. Prescription glasses are effective visual aids that significantly improve a person's ability to see things by focusing on specific areas of weakness in a person's vision.
Prescription glasses are offered at Bright Eyes Optometry in Mt Vernon and the surrounding areas. They usually consist of glass that is uniquely curved. This details of the curve are part of the prescription that the optometrist gives the patient.
If you are finding it difficult to read or see at distances, then prescription glasses may be the solution for you.
Enhance your vision
Glasses improve a person's vision by focusing images in the proper place on the retina. The retina is responsible for reacting to light that comes into the eye and relaying the data to the brain, which creates the images the person sees. In order for these images to be clear, three important things need to occur:
- The image produced by the brain fits into the retina
- The light entering the retina is focused on the surface
- The curves created by the image match the curves in the retina
How prescription glasses work
Each eye contains a lens that lies between the pupil and the retina. The lens works with the cornea, which is known as the transparent cover on the eye. Together, they focus the image on the surface of the retina. One vision issue that people may struggle with occurs when the image focused on the retina is sent too far backward. This can lead to farsightedness, while the image going too far inward can lead to nearsightedness.
Prescription glasses can effectively correct these issues, as well as others, like astigmatism. Also known as crossed eyes, astigmatism is a condition in which the cornea does not have the proper shape. People with crossed eyes are unable to focus both eyes at the same time, which can sometimes lead to double vision and blurriness.

Different types of prescription glasses
There are two types of glasses commonly prescribed by optometrists: minus and plus lenses.
Minus lenses
Minus lenses have a concave shape. They are used to focus images in the proper part of the retina when a person's natural lens and cornea focus the image too close (nearsightedness).
Plus lenses
Plus lenses have a convex shape and are used when the patient's eye focuses the image too far back into the retina (farsightedness). The strength of the prescription given by the optometrist determines how much the lenses alter the focus of the images being sent to the retina.
Common myths about prescription glasses
While there are many myths and misconceptions about these visual aids, two main ones are:
1. Glasses weaken the eye
The only way in which prescription glasses may cause some issues to the patient is if the patient wears a pair of glasses with a different prescription. In general, glasses will not have a negative effect on the patient's eyes if they follow the proper instructions. With prescription glasses, it is possible to enhance one's eyesight with glasses for conditions such as presbyopia, astigmatism, farsightedness and nearsightedness.
However, there is one exception to this rule. The glasses prescribed to young children with lazy or crossed eyes can help to straighten their eyes. Not treating either issue can lead to a permanent condition.
2. Wearing the wrong prescription can damage the eyes
Strictly speaking, this is not true, but it will fail to correct the person's vision problems and usually lead to blurry vision. Wearing glasses with the wrong prescription can also lead to mild headaches, but it does not damage a person's eyes in any way.
