Cataract vs Glaucoma: Key Differences and Risk Factors
Your eyes help you see and experience things. But the problem is when you face any eye problem, the cause may not be clear. Vision changes happen quietly. You may notice things looking slightly dull. Or night driving feels harder than before. Most people ignore it and move on.
This is where cataract and glaucoma come in. They are often spoken about together. This is why many people think they are same. But that is not true. One affects clarity. The other affects vision in a deeper, more serious way. Many people realise the difference only when damage has already begun.
Knowing the difference can help a great deal. By doing so, you will be better able to understand the problem. This will help with timely treatment and recovery. So, read this guide to know what exactly these two problems here. Know their causes, symptoms, and solutions as well.
What Is Cataract?
It is a common condition that impact your eye lens. This lens is the one that helps focus on light to help you see clearly. When it becomes cloudy, you will face problems with vision. This is a common condition with senior citizens. When it loses clarity, vision slowly turns blurred or dull.
Cataract usually develops over time. In the early stage, many people do not feel a strong impact. But as its starts to grow, people will find it hard to do simple things. Reading, driving, or even cooking will be difficult. The vision slowly starts to blur. With time, people will find it hard to recognize things. Timely treatment can easily cure the condition.
For the treatment, an artificial lens is used. It replaces the cloudy lens in your eyes and helps with the fixing of the vision. This is a minor procedure. It usually takes a couple of hours for treatment. The recovery may vary but is usually 7-15 days.
Causes

Impact or high stress on your eyes
Injury or trauma to the eye in the past
Continuous use of steroid medicines
Eye surgery done earlier in life
Symptoms
Cloudy or dull vision making hard to see things

Updated spectacles to manage early vision changes
Better lighting and anti-glare support for daily comfort
Cataract surgery when vision begins affecting routine life
What Is Glaucoma?
This is a condition that impacts your eye vision. This is one that is linked with the optic nerve of the eye. This nerve sends the visual signals to your brain. So, when this nerve is damaged, sending signals becomes hard. This leads to blurring of the vision. Slowly the visibility starts reducing.
This condition is normally linked to pressure in your eyes. It usually develops slowly and without notice. Many people do not notice symptoms. These are seen only when the vision loss starts. One of the most important things to know is that its damage cannot be reversed. But if this detected early, then with the right treatment the effects can be slowed down.
Causes
Increased pressure inside the eye
Poor drainage of eye fluid
Damage to the optic nerve over time
Reduced blood flow to the eye
Long-term use of steroid medicines
Past eye injury or infection
Symptoms
Gradual loss of side vision
Tunnel vision in later stages
Difficulty adjusting to low light
Seeing halos around lights
Eye pain or headache in some cases
Sudden vision loss in rare cases
Risk Factors
Age above 40
Family history of glaucoma
Diabetes or high blood pressure
Long-term steroid medication use
Previous eye injury or surgery
High eye pressure
Diagnosis
Eye pressure test
Optic nerve examination
Visual field test to check side vision
Eye drainage angle examination
Regular eye checkups for monitoring
Treatment
Eye drops to control eye pressure
Oral medicines in some cases
Laser treatment to improve fluid drainage
Surgery if the condition is in advanced stage
Cataract vs Glaucoma: Key Differences

5. Nature of Treatment
Cataract usually needs surgery once. Glaucoma needs ongoing treatment and monitoring.
6. Risk if Ignored
