Optometry

Measuring The Eye Function

I want to know what my eyes stand up to.

How do I know?

I'm in a fix.

Optometry will come to my rescue and examine my eyes.

It will diagnose any problem in the eye structure.

Optometry will also treat the problem if it doesn't entail any major surgical procedure.

It will measure the function of the eyes, i.e., vision too.

It will also correct any anomalies in the function, i.e., vision with the help of lenses and other optical aids.

A Doctor of Optometry is a primary care practitioner for vision and ocular health.

Generally, an optometrist makes an accurate measurement of the refractive errors of the eyes and prescribes the appropriate correction.

They perform comprehensive eye exams in order to diagnose and treat common eye disorders whether of structure or of vision. They refer the case to a specialist in case it deserves so.

Earlier optometry mainly dealt only with the prescription of corrective lenses for defects of vision due to refractive error.

In modern times it has extended its scope by including in itself the fitting of contact lenses as well as of telescopic eyeglasses as an aid to the near-blind.

orthoptics, another new extension, is the practice of strengthening the eye muscles and improving their coordination by eye exercises.

An optician grinds and fits the lenses by reading the prescriptions given by the optometrist.

Until 1904 people used to buy eyeglasses from traveling vendors.

Today it is a specialty profession requiring a four-year postgraduate professional degree!

Sub-specialty residencies that are offered by various schools are:

• Family practice

• Pediatric practice

• Low vision rehabilitation

• Cornea and contact lenses

• Primary care

• Refractive and ocular surgery

• Ocular disease

• Geriatric optometry

• Vision therapy and rehabilitation

Training in binocular vision and orthoptics sub-specialties are often integrated into either pediatric or vision therapy programs.

Vision therapy consists of

• Orthoptic vision therapy : treating amblyopia, strabismus, and double vision or diplopia.

• Behavioral vision therapy : treating difficulties of visual attention and concentration that result in the errors of refractive index as well, namely myopia, hyperopia, presbyopia, and astigmatism.
