An Optometrist Beyond The Optical

Monday, March 28th, 2011


This post will describe what an Optometrist does beyond the optical of eyeglasses and contact lenses. Optometrists detect, diagnose, and treat vision conditions and eye diseases.


Procedures to remove foreign bodies such as metal from the surface of the eye or under the eyelid.


Pre-operative and post-operative care for Lasik and cataract eye surgery.


Cataracts, diabetic eye complications, glaucoma, macular degeneration, and retinal tears and detachments can all be detected through routine eye examinations by an optometrist.


Conjunctivitis, dry eye, glaucoma, macular degeneration, and uveitis are just some of the eye diseases that are routinely managed by optometrists.

5 Causes of Dry Eye

Tuesday, March 22nd, 2011


If your eyes feel irritated, itch, burn, or are occasionally excessively watery then you may have dry eye syndrome. This post will discuss some of the common causes of dry eye syndrome.

1.  Systemic Diseases

Diabetes and autoimmune diseases such as arthritis, lupus, and thyroid disease are all linked to increased rate of dry eye.

2.  Medications

Allergy medications, blood pressure medications, hormone replacement medications, oral contraceptives and excessive caffeine are all associated with dry eye.

3.  Environmental Factors

Pollutants, low humidity, windy or drafty conditions can be contributing factors.

4. Blepharitis

A bacterial infection of the lashes that can cause inflammation and irritation to the eye lid margin where some of the tear glands are located.

5.  Smoking

Is there anything smoking is good for?

Have you or someone you know had trouble adapting to progressive lens in the past?  It may be time to try a new easy to adapt to digital lens.  Free form digital lenses are the latest design improvement for progressive eyeglasses. With computer aided design, free form digital lenses combine information from corneal mapping, subjective refraction, selected frame size, and fitting geometry.  An ideal progressive lens is then computer determined on a point by point basis until a final prescription is produced that can most closely match an ideal lens.

Design Differences:

  • Designed in “real time” and customized to an ideal prescription.
  • Prescription customized for selected frame.
  • Customized for individual frame fitting geometry
  • Fits nearly any selected frame, even small styles.
  • Back-side progressive optics.

Advantages of free form digital lenses:

  • Wider field of vision (up to 50%)
  • Reduced distortion
  • Less image magnification leading to less dizziness (25%reduction)
  • Easier adaption

Digital Progressive Lenses.

Project 365 "Tired of Waiting"

Advanced technology  is finally available to create free form digital progressive eyeglass lenses. This post will discuss a few reasons why custom lenses may be worth waiting for.  There are two basic ways of producing progressive lenses in about an hour:

1. Casting technology is where liquid lens material is added to a mold and then exposed to UV light to form the finished lens.

Disadvantage:  At this time anti-scratch and anti-reflective coatings that can be applied in office on lenses made in this fashion are inferior in quality and they are not available in the newer free form digital style lenses.

2. Semi-finished lenses is where the progressive bifocal has already been ground on the front surface of the lens and then the back surface is ground to meet your distance prescription.

Disadvantage: The anti-reflective and anti-scratch coatings are removed from the back surface in the process leaving only the front surface coatings in tact.  Also, these lenses are not available in the newer free form digital style lenses.

Custom free form digital style progressive lenses are made possible by advances in technology that can combine information from your individual refraction (the one or two portion of the exam),selected frame , and frame fitting geometry to deliver superior vision compared to conventional progressive lenses.
