What is a clinical optometrist?
Optometric examination by a clinical optometrist A clinical optometric examination is performed by an optometrist who has been trained in identifying medical problems and can identify them with the help of guiding questions and specialized tests. Decreased visual acuity that cannot be corrected with standard glasses is examined. The cause of the vision is examined. Cataracts, retinal degeneration, systemic physical problems such as diabetes, and more, and this is of course in addition to the standard problems of nearsightedness and farsightedness […]
Important Important!!! CHARLES BONNET SYNDROME
It is important for me to write about this eye phenomenon that is not talked about enough. It is a syndrome that develops in a significant portion of people who experience partial or complete loss of vision and causes visual hallucinations of things that do not exist. According to studies, the phenomenon is quite common in some eye diseases such as retinal degeneration, glaucoma, diabetic retinopathy. In an eye with normal vision, light enters the […]
Order by numbers – how visual acuity is measured
The term 6/6 vision has become a common term, but what does it actually mean and how is vision tested? A distance vision test is measured using a board 6 meters away under conditions of maximum contrast. (Black on white) in good lighting conditions, using letters, numbers or shapes. During the test, the optometrist presents the numbers and checks what the smallest letter/number/shape the subject can […]
The importance of testing your vision for contrast sensitivity
Contrast sensitivity tests measure the eye's ability to distinguish an object from its background. (CONTRAST SENSITIVITY) In general, contrast sensitivity is affected by lighting, target size, movement, and shape. This test is not routinely performed like a visual acuity test, which measures the size of a letter the eye can see, on a standard viewing plate and at a standard distance. Nevertheless, it is a very important test and provides […]
Poor vision and cognition
A study published last July in the medical journal JAMA investigated the relationship between poor vision and cognition (the brain's use and processing of information). The study found a link between decreased visual acuity, decreased contrast sensitivity, and impaired binocular vision, and between concentration, memory, and language ability. The results provide further evidence of the important connection between vision, eye health, and brain health. On a personal note and from my own experience […]
Raising awareness of eye health to prevent eye diseases and blindness
Sometimes, vision problems develop due to lack of treatment due to lack of awareness of the problem itself or the severity of the condition. Various eye diseases develop slowly and "silently". For example, glaucoma, in which a person does not feel pain or a change in visual acuity and field of vision until the condition is irreversible. Diabetic retinopathy, which develops as a result of poor treatment of diabetes and retinal degeneration. It is very important to monitor […]
Microscopic glasses with built-in light
A solution for reading with built-in light – Many studies have shown the relationship between reading ability and the intensity and type of lighting. Watch a video about microscope glasses with built-in light.
Online vision test for reading
Remote Vision Test – Initial Vision Test for Reading In light of the new routine of life alongside the Corona virus, many patients are at home for many hours. Some have difficulty reading a book, newspaper, solving crossword puzzles or other activities as a result of eye diseases that affect their vision. For this purpose, an initial reading test was developed that is performed remotely and provides information about the patient's vision status. This information […]
Low vision filters
Color and filters What is the difference? Tinted lenses (such as in sunglasses) reduce the amount of light entering the eye. The darker the color, the less light will enter the eye. Therefore, a very dark lens can only transmit 2% of light into the eye, and light tinting can transmit 50%-60% of light into the eye. Color reduces the amount of light entering the entire spectrum and does not distinguish between waves that interfere with vision […]
Eye examination for visually impaired people as a routine examination
With the advancement of medicine and the treatment of diseases of old age, there has also been a huge improvement in the treatment of diseases that cause blindness, such as glaucoma, diabetes, macular degeneration, and more. Many older people suffer from visual impairment that remains despite treatment. Over the years, there has been a tendency to define poor vision and divide it into categories and visual acuity. This division is convenient for deciding who is considered by law to have vision […]
