Eyeglasses & Eyeglass Lens Options with your College Station Optometrist
Eyeglasses of one sort or another have been around since the 13th Century, during which time they have gone from rudimentary vision aids to fashion accessories available in a variety of styles from leading designers. But no matter how beautiful a pair of frames may look, they won't do you much good unless the lenses they contain suit your vision needs perfectly. That's why our eye doctor at Crystal Vision Center, Dr. Sherri Brice, provides a wide range of eyeglass lens types and options for our College Station clientele.
Why Do You Need Eyeglasses?
The principal role of eyeglasses is to correct the vision problems caused by refractive errors -- abnormalities in the way the eye refracts the light that passes through it. Ideally, the incoming light is focused by the lens so that when it reaches the back of the eye, a sharp image forms for transmission to the brain's vision center. If the eyeball is too long or too short, the image comes into focus in front of or "behind" the retina, causing nearsightedness or farsightedness. Astigmatism is caused by irregularities in the cornea. Presbyopia occurs when the lens grows too stiff to focus light efficiently. Eyeglass lenses are specially ground to compensate for your individual type and degree of refractive error, altering the refraction pattern so that the back of the eye gets a clear image.
Types of Eyeglass Lenses in College Station
The primary categories of eyeglass lenses are single-vision and multifocal. Single-vision lenses have the same degree of correction across the entire lens; they're ideal for a simple case of farsightedness or nearsightedness, with or without astigmatism. But if you have presbyopia, you'll be better served with multifocal lenses that contain two or more corrections (such as near vision and distance vision). Traditional bifocals or trifocals place these corrections is separate zones, while progressive multifocal incorporate a smooth gradation between visual fields. Our eye doctor can determine whether you need multifocal and write your prescription accordingly.
Whatever your eyes require, you'll find that you also many other options when choosing eyeglasses lenses. For instance, you may decide to get lenses made of tough polycarbonate plastic, especially if you're buying them for active kids or going with a rimless frame. (Polycarbonate lenses also offer built-in UV protection.) Trivex is another popular, lightweight lens material. You might even opt for high-index lenses that are super-thin and super-light. Other useful additions include:
- Anti-glare coatings
- Special filters that block some of the blue light emitted by computer screens
- Polarized lenses for reducing glare and reflections
- Tinted lenses or "transition" lenses that vary their degree of tint in response to light
