How was the eye exerciser developed?
The concept of eye excercises has existed right from Greek times—Euclid’s work on optics, Plato’s theory of vision and Aristotle’s familiarity with myopia are known to any student of antiquity.
Eye Ache
It is difficult to define what is really meant by this. The closest definition would range from an uncomfortable sensation in or around the eye to positive low pain in the globe. Common cause are:
(a) Any error of refraction like myopia, hypermetropia or astigmatism. It is notable that the small errors cause aches, not large errors. With a large error the eye makes no attempt to compensate by exerting itself and therefore “comfortably” decides not to see. With a small error, it attempts to bring the object into focus continually and therefore strains, resulting in eye aches.
What is the treatment for retinal detachment?
Once the diagnosis
is established, usually the patient is put on complete bed rest.
This has the advantage of settling the retina down and decreasing the height of the detachment. At the same time a detailed examination is done for holes or tears in the retina, as they all have to be detected in advance and the position of each plotted on a chart or retinal map for successful treatment.
Eye Stye
A stye is a painful nodule (a boil) on the edge of the lid, usually from bacterial infection of the glands buried at the root of the eyelash.
It is quite painful and can be extremely tender to the touch. After a short time, a yellow point (a pus point) appears on the lid margin, the stye tip bursts and the swelling in the lid settles down.
The eye is a delicate organ and can easily be damaged by careless handling or by using inappropriate medicines. Whenever possible, consult your eye surgeon. The first aid pointers below are for emergencies and when the services of an eye surgeon are not immediately available.
How does one check that the child’s eye is developing properly?
The eye has two basic abilities: (1) Raw sight or colour and black white vision with all its attendant abilities to see in the light and dark. (2) Ability to locate and fix on an object, thus simultaneously changing focus and judging an object’s distance and depth.
