Glass prescription can be difficult to understand, especially when no one else in the family has worn glasses before. Most patients are puzzled by the ‘signs’ and ‘numbers’ on the glass prescription and would want to ask a lot of questions regarding it to the doctor, but are either too “shy” or they are gently “shoved out” of the consulting room for want of the doctor’s time.

When we look straight at an object we see not only the object focused on, but also the objects to the side of it, which is defined by limits on all directions. this is the visual field. Scotoma is a non seen area within a seeing area. it can be due to disorders of the optic nerve, the nerve which connects the eye to the brain or macular problem-the central area within the eye which is responsible for central fixation of the eye.

The child will be asked to wear a patch on the better seeing eye for 2-6 hours a day depending how lazy the eye is. It is best if during this time, close work, reading or colouring is encouraged in order to encourage the lazy eye to see. Atropine eye drops or ointment will blur the vision and dilate the pupil. It is long lasting and only needs to be given once or twice a week. As the sight in the better eye is now blurred, the child will be forced to use the lazy eye more. This treatment is expected to improve the vision in the lazy eye. It is usually reserved for “mild” to “moderate” lazy eyes cases.

Cylinder is the measure of astigmatism. Astigmatism is when there’s an irregular shape to the cornea, often described as a football shape. It causes blurriness at any distance. There are two measurements that go along with astigmatism, the first, cylinder, is a measure of how severe the astigmatism is.

The cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.
