Weak Eyesight Symptoms and Tips to Improve Vision

 

Weak eyesight or a visual impairment impacts millions of people around the world, making everyday tasks like reading, driving, and even recognising face challenges. It can develop due to various reasons, including genetics, ageing, or lifestyle habits. Some of the common symptoms of weak eyesight include blurred vision, headaches, and difficulty seeing in dim light.

 
Therefore, early detection and proper care can help prevent further deterioration. In this blog, we explore how to know if your eyesight is weak, its symptoms, causes, prevention and treatment options.


How to Know Your Eyesight Is Weak? 


The best way to determine if your eyesight is weak is by checking how well you can see things at various distances. A common method for this is the visual acuity test, which typically involves using a Snellen eye chart to evaluate your vision from 20 feet away.

 

  • Understanding Your Score: Scoring a perfect 20/20 means your vision is right on track. But if you find yourself with a score of 20/70, it indicates that you need to be just 20 feet away to see what someone with normal vision can spot from 70 feet away. The World Health Organization (WHO) considers this to be moderate low vision, and if your score dips to 20/200 or worse, that falls into the category of severe low vision. 
  • Other Vision Tests: A visual field test is designed to check your side vision. If your peripheral vision is 20 degrees or less, it is also classified as low vision.

What are the Symptoms of Weak Eyesight?


Here are 20 common signs and symptoms of weak eyesight that you should know about:

 

  1. Blurred Vision: Objects appear unclear or out of focus, making everyday activities like reading, driving, or recognizing faces difficult.
  2. Frequent Headaches: Persistent headaches are one of the most common symptoms of weak eyesight, especially after reading, using digital screens, or focusing for long periods, which may indicate eye strain.
  3. Halos Around Lights: Seeing bright rings or circles around light sources, particularly at night, may suggest refractive errors or cataracts.
  4. Night Blindness: Struggling to see in dim lighting or at night can make driving and navigating dark environments challenging.
  5. Glare Sensitivity: Excessive discomfort when exposed to bright light, such as sunlight or headlights, can be a sign of weak eyesight.
  6. Eye Pain: Persistent pain in or around the eyes should never be ignored, as it may indicate an underlying eye condition.
  7. Red Eyes: Bloodshot eyes can result from strain, dryness, or inflammation.
  8. Eye Fatigue: Tired, achy eyes after prolonged screen exposure or reading can be a sign of vision weakness.
  9. Difficulty Concentrating: Poor vision can lead to trouble focusing on tasks, affecting work or studies.
  10. Flashes of Light: Seeing sudden flashes, even without an external source, may indicate a retinal problem requiring urgent medical attention.
  11. Fluctuating Vision: The clarity of vision changes throughout the day, which can be disorienting and interfere with daily tasks.
  12. Loss of Central Vision: Difficulty seeing objects directly in front of you can be a serious symptom that affects tasks such as reading or recognizing faces.
  13. Dry Eyes: A constant sensation of dryness, irritation, or discomfort may be caused by inadequate tear production.
  14. Light Sensitivity: Increased sensitivity to light can lead to discomfort, eye strain, and difficulty in performing routine activities.
  15. Floaters: Small, shadowy specks floating in your vision are common but should be monitored if they increase in number.
  16. Squinting: Frequently narrowing the eyes to see clearly may indicate an underlying vision problem, such as myopia or astigmatism.
  17. Burning Sensation: A stinging or burning feeling in the eyes may indicate dryness or irritation.
  18. Distorted Vision: Objects appearing wavy or warped may signal corneal or retinal issues.
  19. Hazy Vision: A foggy or unclear view can make it hard to see objects sharply and clearly.
  20. Change in Iris Color: Any noticeable change in the iris colour is rare but could indicate an underlying eye condition.


If you experience one or more of these symptoms, please consult an eye specialist for an examination. Please note that these symptoms may vary depending on the intensity and underlying cause of the condition.


What are the Causes of Weak Eyesight?


Weak eyesight can result from various factors, including medical conditions, age-related changes, and external influences. Below are some common causes:


●  Refractive Errors


These can happen when your eye’s shape prevents light from focusing correctly on the retina, causing blurred vision. Some of the refractive errors are myopia (nearsightedness), hypermetropia (farsightedness), astigmatism, and presbyopia.


●  Age-Related Macular Degeneration (AMD)


A progressive condition that affects the central part of the retina, leading to a gradual loss of central vision. This condition is more common in older adults.


●  Cataracts


A condition where the eye’s lens becomes cloudy, resulting in blurry or dim vision. Cataracts develop gradually and can significantly impair eyesight over time.


●  Glaucoma


This disease damages the optic nerve, which transmits visual signals from the eye to the brain. Glaucoma often develops silently and can lead to peripheral vision loss if left untreated.


●  Diabetes-Related Eye Problems


Diabetes can lead to diabetic retinopathy, where blood vessels in the retina are damaged due to high blood sugar levels, resulting in vision impairment.


●  Eye Injuries and Trauma


Any physical injury or trauma to the eye can lead to temporary or permanent vision problems. Immediate medical attention is crucial to prevent further damage.


●  Optic Atrophy


This refers to the gradual deterioration of your optic nerve. This condition can stem from various factors, including injuries, infections, and problems with blood circulation.


●  Trachoma


Trachoma is a bacterial infection that can cause irritation and harm to your eyes. It's one of the top reasons for vision loss and blindness around the globe, particularly in developing countries.


Addressing the reasons of weak eyesight by making some lifestyle adjustments and keeping up with regular eye check-ups can really help prevent serious decline or loss of vision.

How To Prevent Weak Eyesight?


Your eyes play a crucial role in your overall health, and taking preventive measures can help maintain good vision. Here are some essential tips to prevent weak eyesight:


1. Get Regular Eye Exams


Even if you don’t experience vision problems, regular comprehensive dilated eye exams help detect early signs of conditions like glaucoma, diabetic eye disease, and age-related macular degeneration. Many vision issues can be managed effectively if diagnosed early.


2. Wear protective Eyewear 


Protective Eyewear like safety glasses, goggles, or eye shields can protect your eyes while working in hazardous environments or playing sports. You should also wear sunglasses when going out. It blocks 99–100% of UV-A and UV-B rays to prevent sun damage.


3. Follow Healthy Screen Habits


Extended screen time can cause eye strain and fatigue. Follow the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds to reduce strain.


4. Maintain Proper Hygiene


If you wear contact lenses, wash your hands thoroughly before handling them. Disinfect and replace them as per your eye care professional’s instructions to avoid infections.


5. Eat a Nutritious Diet


A diet rich in leafy greens (spinach, kale), carrots, and omega-3 fatty acids (salmon, tuna) helps protect eyesight and reduce the risk of vision problems.


6. Manage Your Health and Chronic Diseases


Maintaining a healthy weight can lower the risk of diabetes-related eye issues. Also, it is important to control your blood sugar levels to prevent diabetic retinopathy, a leading cause of blindness.


7. Know Your Family History


Some eye conditions are hereditary. Being aware of your family's eye health can help with early detection and prevention.


8. Quit Smoking


Smoking increases the risk of cataracts, optic nerve damage, and macular degeneration. If you smoke, quitting can significantly benefit your eye health.
