CATARACT AWARENESS: UNDERSTANDING SYMPTOMS AND PREVENTION<\/h2>\n\n\n\n

What is a Cataract?<\/strong><\/h2>\n\n\n\n

Cataract<\/a> is one of the most common eye conditions that progresses slowly. They develop when the lens of the eye, which is normally clear, becomes cloudy. This cloudiness impairs vision by reducing the amount of light entering the eye and reaching the retina(the innermost layer of the eye).<\/p>\n\n\n\n

Types of cataracts<\/strong><\/h2>\n\n\n\n

Primarily, there are three types of cataracts:<\/p>\n\n\n\n

    \n
  1. Nuclear sclerosis cataract-<\/strong> In this condition, the central part of the eye lens (nucleus) gets cloudy, yellow, and hard.\u00a0<\/li>\n\n\n\n
  2. Cortical cataract- <\/strong>This cataract occurs due to overhydration. Wedge shape opacities develop in the edges of the lens. Stages of cortical cataract appear when they gradually progress towards the center of the lens.\u00a0<\/li>\n\n\n\n
  3. Posterior Subcapsular cataract- <\/strong>The innermost layer of lens becomes opacified giving a very high amount of vision loss.<\/li>\n<\/ol>\n\n\n\n

    What are the causes of cataracts?<\/strong><\/h2>\n\n\n\n

    Most people find this problem reaching the age of 50-60. However, some other factors also <\/p>\n\n\n\n

    contribute to the development of cataracts:<\/p>\n\n\n\n

    Eye injury<\/strong>: Eye injury damages the crystalline lens and changes the lens fiber.<\/p>\n\n\n\n

    Excessive exposure to ultraviolet (UV) rays:<\/strong> UV rays can affect the DNA and change the eye lens’s protein structure. <\/p>\n\n\n\n

    Smoking: <\/strong>Smoking causes oxidation in eye lenses, contributing to eye lens physiology change.<\/p>\n\n\n\n

    Using steroids for longer periods<\/strong>: Long-term use and high doses of steroids can cause Subcapsular cataracts.<\/p>\n\n\n\n

    What are the symptoms of cataracts?<\/strong><\/h2>\n\n\n\n

    Some of the common symptoms are:  <\/strong><\/p>\n\n\n\n

    Diminision of  vision<\/strong>: Cataracts block the passage of light toward the retina. <\/p>\n\n\n\n

    Light sensitivity:<\/strong> Scattered light reaches the retina, and it is bright.<\/p>\n\n\n\n

    Double vision:<\/strong> The outcoming light is scattered through the cloudy buildup, which sometimes causes the formation of multiple but unclear images.<\/p>\n\n\n\n

    Difficulty in seeing during the night: <\/strong>More light is required for scattering and image formation in darkness. <\/p>\n\n\n\n

    Seeing halos around lights: <\/strong>The light becomes diffracted due to a cloudy lens, and Halos around light is created.<\/p>\n\n\n\n

    How can one detect cataracts in the early stage?<\/strong><\/h2>\n\n\n\n

    How does one detect cataracts in the early stage? Sounds like an interesting question.<\/p>\n\n\n\n

    In the early stage, cataract is unnoticeable. A cloudy, dim, or blurred vision starts developing gradually.  The vision seems <\/p>\n\n\n\n
