World Sight Day: Because everyone deserves a better vision

14 October, 2021 Anuja Sahi

World Sight Day is a global awareness day observed every year on the second Thursday in October to draw attention to vision impairment, including blindness. Every year it is commemorated on the second Thursday of October, thus in 2021, the event falls on 14th October. The theme for World Sight Day, 2021 is Love Your Eyes

One billion people worldwide have a vision impairment that is either preventable or unaddressed. Reduced or missing vision can have a significant and long-term impact on all parts of life, including daily personal activities, community interaction, school and career chances, and access to public services.

One of your most significant assets is your vision, hence maintaining the health of your eyes must be your primary focus, let us know about some of the common eye-related problems that can help you diagnose your vision better before it gets late.

  • Cataracts: These are hazy patches that form in the lens of the eye. A healthy lens is as clear as that of a camera. It allows light to get through to your retina, which processes images at the back of your eye. Light can’t get through as easily when you have a cataract. As a result, you may notice glare or a halo surrounding lights at night, and you won’t be able to see as well.
    Cataract often occurs without having the symptoms of pain, redness, or tearing in the eye.
  • Conjunctivitis (Pinkeye): Conjunctivitis, often known as pink eye, is an inflammation of the tissues that line the back of your eyelids and cover the sclera (conjunctiva). As a result, your eyes may become itchy, red, hazy, teary, and discharge, giving you the impression that something is in your eyes. It’s also one of the most common kinds of vision issues.
    Though highly contagious, it is rarely serious and is unlikely to cause visual damage, especially if detected and treated early. Let us know in details about the types of Conjunctivitis.
    • Allergic Conjunctivitis: People who already suffer from seasonal allergies are more likely to develop allergic conjunctivitis. When they come into contact with a material that causes an allergic reaction in their eyes, they develop it.
    • Giant Papillary Conjunctivitis: People who wear hard or rigid contact lenses or soft contact lenses that are not updated frequently are affected by this condition, which is caused by the presence of a foreign body in the eye for an extended period of time.
  • Bacterial Conjunctivitis: Bacterial conjunctivitis is another prevalent illness that is caused by bacteria and is highly contagious. Unlike the viral pink eye, which produces a watery discharge, bacterial conjunctivitis results in a thick white, yellow, or green discharge from the infected eye(s). Pink eye caused by bacteria normally clears up on its own in one to two weeks, but if the condition persists, antibiotic eye drops may be required.
  • Chemical Conjunctivitis: Such type of conjunctivitis can be caused by air pollution, chlorine in swimming pools, or other reason may be exposure to noxious chemicals.
    • Corneal Diseases: The cornea is the front of your eye’s clear, dome-shaped “window.” It aids in focusing the light that enters. It can be harmed by disease, infection, injury, and toxic exposure. Among the warning signs are:
      • Red and watery eyes
      • Pain
      • Reduced vision
    • Retinal Detachment: The term “retinal detachment” refers to when the retina is separated or detached from the underlying tissues that keep it in place within the eye. It can start with little sections of the retina being damaged and progress to retinal detachment. The longer you wait to treat a retinal detachment, the more likely you are to lose whole vision in the affected eye.

Apart from these vision problems other eye-related problems are:

  • Uveitis
  • Eyestrain
  • Night Blindness
  • Color Blindness
  • Eye floaters

Ways to keep eyes healthy

  • Take a healthy and balanced diet
  • Continue with regular exercise
  • Wear protective eyewear
  • Give rest to your eyes, off from blue light
  • Keep a check on family history related to eyes


The eyes are intricate, and it’s crucial to understand the various components and how they work. Knowing each part and its functions can help you spot visual difficulties and symptoms of common eye conditions early on, allowing you to obtain treatment and keep your eyes healthy.
