Overview

A clear starting point

Vision plays a critical role in every stage of life, yet billions of people globally experience vision impairment that could be prevented or treated. Common conditions include refractive errors, cataracts, glaucoma, and age-related macular degeneration. While some vision changes are a normal part of aging, proactive steps such as comprehensive dilated eye exams and healthy lifestyle choices can significantly reduce the risk of severe vision loss. Timely access to quality eye care is essential for maintaining optimal eye health and addressing conditions early before they cause irreversible damage.

Four key facts

  1. 1Globally, at least 2.2 billion people have a near or distance vision impairment, and almost half of these cases could have been prevented or are yet to be addressed.
  2. 2The leading causes of vision impairment and blindness worldwide are uncorrected refractive errors and cataracts.
  3. 3Getting older increases the risk of eye diseases such as age-related macular degeneration, glaucoma, and cataracts.
  4. 4Conditions like diabetes and high blood pressure can significantly increase the risk of developing serious eye problems like diabetic retinopathy.

Useful points to discuss

Schedule regular comprehensive dilated eye exams, as many eye diseases have no early warning signs.
Protect your eyes from UV radiation by wearing sunglasses that block 99 to 100 percent of UVA and UVB rays.
Maintain a healthy lifestyle by eating a balanced diet rich in leafy greens, staying physically active, and quitting smoking.

When professional care may be important

These examples are not a diagnosis checklist. New, severe, rapidly worsening, or concerning symptoms should be assessed by a qualified healthcare professional; emergencies require local emergency services.

  • Sudden loss of vision or severe blurriness in one or both eyes.
  • Intense eye pain, especially if accompanied by redness, nausea, or vomiting.
  • Seeing flashes of light, new floaters, or a shadow across your field of vision.
