Symptoms of cataract
Cataract patients usually describe their eyesight as seeing through clouded lenses and gazing through a frosty or fogged-up window. Cataracts can cause clouded vision, making it difficult to read, drive a car (particularly at night), or see the expression on a friend’s face. better lighting in the morning and eyeglasses can help you deal with cataracts at first, but they will eventually reduce your vision considerably and interfere with your activities.
Cataract advancement typically increases the dioptric ( refraction ) power of the lens, resulting in mild-to-moderate short-sightedness. As a result of so-called myopia (short-sightedness), presbyopic individuals who were unable to focus on near objects report improved near vision and decreased need for reading glasses. However, this is a transient phenomenon, and when the optical quality of the lens deteriorates, the visual acuity becomes very poor. Transient myopia associated with cataracts is not common in cortical and posterior subcapsular cataracts.
Double vision is a common complaint of patients with the initial stages of cataracts. Diplopia (double vision) of cataracts is usually monocular and caused by the perception of two images from one eye (the diseased one). The double vision of cataracts is believed to be caused by lens opacity separating the one point on the retina on which the collected light beam into two points. This condition could also be presented as halos around light. light sensitivity in patients with cataracts is found to be less common than the previously mentioned symptoms.
