Who needs glasses?
Eventually, everybody. A person with normal vision is able to see clearly
near objects (e.g. read fine print) as well as objects far away in the
distance. As we grow older, the ability to see near objects decreases
(presbyopia). Even people born with normal vision, once they reach 40
to 45 years of age, will require vision correction to read.

____________________________________________________________
Half glasses.
- Correct near vision only (reading glasses).
- Often the least expensive option.
top
_____________________________________________________________
Reading glasses
- Correct near vision only.
- Relatively inexpensive.
- Must put them on when doing near work and remove them to see at distance.
- Inconvenient if your work requires frequent change between near and far gaze (bank teller, salesperson, secretary, etc.)
top
_____________________________________________________________
Bifocal glasses
- Correct near vision (bottom portion) and, when necessary, also distance vision (top portion).
- If your distance vision is normal, the top portion is plain glass (no prescription).
- More expensive than reading glasses.
- Rarely misplaced or forgotten because they are worn continuously.
- Need getting used to them.
top
_____________________________________________________________
"Double" bifocal glasses
- Bifocal glasses with near correction at top and bottom
- Professions requiring near correction in up gaze may benefit (painters, electricians, mail sorters, etc.)
top
_____________________________________________________________
No-Line bifocal glasses
- Nearly invisible separation between the upper and lower portions.
- Work the same way as bifocals.
- Cosmetically pleasing.
- More expensive than bifocal glasses.
top
____________________________________________________________
Trifocal glasses
- Top part is for distance, bottom part for reading and middle part for intermediate viewing
- Suggested for people who need to see clearly charts or papers anywhere on the desk (accountants, architects, typists, pianists, etc.)

Why contact lenses?
People choose contact lenses for different reasons. Some of them are:
- Improved appearance.
- More natural eyesight correction. *
- Greater safety in body contact sports.
* All spectacles, framed or not, limit side vision. Unconsciously, spectacle wearers must turn their head from side to side to obtain adequate side vision. With contact lenses there is a wider field of vision with no side "blind spot". This is helpful to automobile drivers and is a necessity in sports. Contact lenses do not fog with abrupt changes in temperature or from breathing during sports or hard physical activity. Rain and snow do not blur the vision because eyelid action keeps the lens surface clean.

The process of fitting new contact lenses involves several visits to the office. To simplify the process, please tell the person making your appointment that you are interested in contact lenses. We will then give you an appointment for a complete medical eye exam followed by a separate appointment, on the same day, with our contact lens technician. If you decide against trying contact lenses, there is no charge for appointment with the contact lens technician.
After the health status of your eyes is determined, a prescription for glasses will be issued and you will be told whether or not you are a candidate for contact lenses. The fee for the eye exam is the same whether you are interested in glasses or contact lenses.
Because we stock many lenses we might be able to give you the lenses to take home the same day. A $100 deposit is required before taking the lenses home. You will be trained in the proper care of your new lenses before you leave the office.
The fees for contact lenses fitting, training and materials vary considerably with the type of lenses. You will be informed about the cost after the initial decision on lens type is made.
