Frequently Asked Questions About Eyeglasses
Do you have to squint to read books or road signs? Do you have glasses, but haven't updated your prescription in a few years? If you have questions about getting new glasses, replacing old glasses, or repairing your current glasses, our team at A B Vision Eyecare can help. If you live in or around Kingston, Linstead, or Jamaica, contact Dr. Mattis to schedule your next eye exam. We have gathered a few of the questions we run into regarding eyeglasses.
What is the difference between an ophthalmologist and an optometrist?
Optometrists perform routine eye exams, diagnose eye conditions, write prescriptions for vision products, and offer vision care after surgery. Ophthalmologists are doctors that perform eye surgeries and provide therapy for eye diseases. We offer all of the services provided by optometrists and more, including exams for eyeglasses.
How often should I update my eyeglasses prescription?
At the very least, receive an eye exam once per year. An exam doesn't mean updating your prescription or buying new glasses, but it can catch subtle changes in your vision before they become worse.
Are bifocals, trifocals, or progressive lenses optional?
Not being able to see well may involve multiple problems. It is not as simple as having strong or weak eyes. The shape of your eyes, the type of eye disease, or damage can cause nearsightedness or farsightedness. You may need these special types of lenses to have great vision at multiple distances.
What do the numbers on a glasses prescription mean?
Here are a few measurements that you can find on vision prescriptions:
- SRX: Eyeglasses
- CLRX: Contact lenses
- OS (Oculus Sinister) the left eye.
- OD (Oculus Dextrus) right eye.
- OU (Oculus Uterque) both eyes
- D (Diopter) specific correction strength (or the power of your lens) needed.
- + (Positive sign) Farsighted or Presbyopia
- - (Negative sign) Nearsighted or Myopia
- S (Spherical) degree of near or far, just like D
- C (Cylinder)
- Axis, Alignment, or direction of astigmatism (upper, lower, left, right)
- DV (Distance vision)
- NV (Near vision)
- Prism - Lenses are built with prisms to direct light into your eye a certain way.
- PD (Pupillary Distance) The distance between the center of each eye, measured in millimeters.
