Macular degeneration is a relatively common disease. Yet, the damage that it inflicts on one’s vision can, at times, be quite severe. This disease attacks eyes at a relatively older age, usually over the age of 60. Macular degeneration, also known as Age-related Macular degeneration (AMD), is the primary cause loss of reading vision in […]

The Amsler grid is a quick and simple test that any patient can perform at home. Its purpose is to check the integrity of the central retina, known as the “macula”. The aim of this test is primarily to rule out the development of a disease known as Age-dependent Macular degeneration (AMD). This very simple
This section will discuss the question: what information does your prescription for new glasses contain? and what makes one pair of glasses different from another? Firstly, a short description of the glasses themselves: each one of the lenses is characterized by a number that is also known as “the corrective power” of the lens and expressed in
What Makes Each Pair of Glasses Unique Read More »
Below you will find a description of each of the refractive errors that require glasses. Thus, if you, a friend, or a family member wears glasses, you will be able to better understand the characteristics of the visual disturbance. You will also learn what is unique to the pair of glasses required to correct each

The Necessity for Glasses in Order to See Clearly From a Distance Myopia is a condition in which a healthy eye is slightly, up to a few millimeters, larger than a standard sized eye. As a result, the eye is not in focus, the image that one views, does not fall precisely on the retina
Nearsightedness (Myopia) Read More »
Eyes that require glasses can be divided into those that are nearsighted and those that are farsighted. Those that are nearsighted (myopic) require glasses with a minus number, while those that are farsighted (hyperopic) require glasses with a plus number. A farsighted (hyperopic) eye, is an eye that is somewhat smaller than average. If a

This section discusses astigmatism and cylinder. These are two phrases that people who wear glasses often hear, but do not always receive a thorough enough explanation on what they actually mean. Shortly I will try to explain these terms in a simple manner, comprehensible also to those that have not majored in optics and physics

The Necessity for Reading Glasses over the Age of 45 Throughout the course of a person’s life, the eye undergoes various changes in structure and function. These are normal changes and do not indicate illness. One of these changes is connected to the fact that the natural lens, which is responsible for the focusing mechanism
It is not good news for a person who never wore glasses their entire life, to suddenly, some point between the ages of 44 and 47, “giving in” and visiting an optometrist complaining that he/she can no longer see objects that are nearby in focus, and that he has difficulty reading small letters, particularly for
During a person’s lifetime his prescription for glasses will change many times, perhaps once every five years, but occasionally even once a year. The refraction generally changes at a much more rapid rate during puberty, associated with the general growth of the rest of the body. In addition, the prescription of one’s glasses will change at
