Q

Optometric horizon of today are expanded into 2 directions:

A

Preventive optometry
Field of visual enhancement

23
Q

Explain preventive optometry

A

Optometrists are no longer satisfied in prescribing lenses as a prosthetic device, but consider them a means of maintaining the visual efficiency of the patient in spite of the impact of school or industry.

24
Q

Explain field of visual enhancement

A

Increase visual efficiency for these patients so that they can perform their jobs easily, quickly, and accurately.

25
Q

Old idea of optometry:

A

Correction of EOR
Refractionist

Refractive approach-inadequate

26
Q

New idea of Optometry:

A

To provide an environment in which the individual can re-adapt himself to his life necessities
Optometrist
Vision is a function that involves the whole organism. Eyes cannot be studied in isolation.
More emphasis on binocular vision and more attention given to near-point seeing problems.

27
Q

Includes the visual acuity of the individual in his environment

A

Vision

28
Q

Does not force the patient to give up all accommodative effort, but to maintain it a minimum level which is conductive to that individual

A

Fogging technique

29
Q

Purpose of case analysis

A

(A) Find the limitations of the prescriptible lens for distance and for near

(B) To determine whether the case can be handled by: lens application alone, by vision training and lenses, or by vision training alone;

(C) To follow the changes in relationship between accommodation and convergence brought about by the new Rx or the vision training program or both (progress report examination)
