EMMETROPIA
Emmetropia is the refractive state of the eye, parallel rays of a light from a distant object are focused on the retina, with accommodation at rest.
MYOPIA [short sightedness]
Myopia is a refractive error, the rays of light focused on in front the retina. In this case distant objects are seens blured.
SPECTACLE CORRECTION.
It can be corrected by concave lenses.
Contact lens correction
Contact lens is advisable for high Myopia. They can eliminate the peripheral distortion and minification from strong concave lenses.
HYPERMETROPIA [Longsightedness]
Hypermetropia is a refractive error. The rays of light focused behind the retina.
SPECTACLE CORECTION
It can be corrected by convex lenses.
CONTACT LENS CORECTION
Contact lens is advisable for high hypermetropia. They can reduce the perpheral aberration and magnification from the strong conven lensees.
Contact lenses are indicated in unilateral hypermetropia.
CONTACT LENS CORRECTION.
Spherical contact lenses can optically correct up to moderate degrees of astigmatism.
for higher degrees of astigmatism, torric contact lenses are needed.
PRESBYOPIA [EYE SIGHT OF OLDAGE]
This is a physiological aging process in which the near point gradually recedes beyond
The normal reading distance.
TREATMENT
Prescribing convex spherical lenses at a comfortable working or reading distance required by the patient.
ASTIGMATISM
Astigmatism is a type of refractive error, The refraction varies in different meridian the rays of light entering the eye can not convert to a point focus.
SPECTACLE CORRECTION
IT can be corrected by cylindrical lenses
Importance of Eye Examination
In today�s working environment, given the ever-increasing expectations for efficiency and performance, good vision is critical to ensure the ability to produce good results.
Most of us are either too busy or too lazy to realise we have uncorrected vision problems
Today�s job profile, family entertainment, and even household tasks often require some degree of computer usage. Studies have shown that approximately 10 million people suffer from vision problems caused by the prolonged exposure to the computer.
The sooner the problems are diagnosed, the better are the chances of a successful treatement.
| Many studies have a report on Early Detection discovered that much of the population remains largely unaware of how important routine eye exams are to their health and well being. In many countries people at increased risk for vision loss are unaware of the risks of certain eye diseases, therefore fail to take advantage of early detection measures available from eye care professionals. | |
| The study conducted by the Global Campaign Report suggested most people failed to get regular check ups in part because they did not realize anything was wrong with their eyes. However, even if your eyes seem to function well, it is important you get annual or at least bi-annual exams to help predict and detect problems down the road early on. | |
| Eyes are precious and most sensitive part of the body. | |
| Poor vision is a hazardous in every day life, not only for driving but also for in routine work. | |
| Regardless of your age or physical health, it is important for everyone to have regular eye exams. |
A regular eye check-up allows your Eye Care Professional to monitor your eyesight
A regular eye exam is the best way to protect your eyesight-- and an easy precaution to take-- as many sight-threatening diseases can be cured or slowed if caught early enough. So the sooner the problems are diagnosed, the better are the chances of a successful treatment.
When should you consult your eye care practitioner
| It is particularly important to have an eye exam if you notice a change in your vision. | |
| Feeling strain and headache, especially in front of computers. | |
| Your eye care practitioner may recommend more frequent eye exams if you have a family history of eye disease. | |
| If your eye is injured or having severe pain and red eyes in any way, you should contact an Ophthalmologist. |
