What are cataracts? Cataracts are cloudy areas that form in the natural lens of the eye, making vision look blurry, hazy, dim, or less colorful over time. They are very common with age, and while early cataracts may only need monitoring, cataract surgery may help when vision changes begin to interfere with reading, driving, work, hobbies, or daily life.

For many people, cataracts do not appear all at once. They usually develop slowly. One day, the headlights seem brighter. Colors look duller. Reading feels harder. Your glasses may not sharpen things as well as they used to.

At Southwest Eye Institute, patients in El Paso, including Common, Mesa, Dyer, and Resler, as well as nearby Las Cruces, can receive cataract evaluations and treatment options designed to restore clearer vision when cataracts begin affecting daily life. Cataract removal is important for preventing severe vision loss, and the practice offers resources on cataracts, lens options, post-surgery recovery information, and guidance for surgery preparation.

What Are Cataracts?

Extreme cataract in the left eye to show patients what are cataracts at Southwest Eye Institute. Cataracts happen when the normally clear lens inside your eye becomes cloudy. This lens helps focus light onto the retina so you can see clearly. When the lens clouds, light scatters before it reaches the retina, and your vision can become blurry, dim, or hazy.

Most cataracts are related to aging. The proteins in the lens can break down and clump together over time, creating a cloudy area on the lens. This cloudy area can grow and make more of the lens cloudy.

Cataracts can develop in one eye or both eyes. They do not spread from one eye to the other, but both eyes can develop cataracts over time.

Common Cataract Symptoms

Cataracts may not cause noticeable symptoms at first. As they grow, symptoms can become easier to recognize.

Common cataract symptoms include:

  • Blurry or cloudy vision
  • Hazy or dim vision
  • Faded or yellowed colors
  • Trouble seeing at night
  • Glare from sunlight, lamps, or headlights
  • Halos around lights
  • Frequent glasses or contact lens prescription changes
  • Double vision in one eye
  • Trouble reading or doing close work
  • Difficulty driving, especially at night

The National Eye Institute lists blurry vision, faded colors, light sensitivity, difficulty with night vision, halos, double vision, and frequent prescription changes as possible cataract symptoms.

What Causes Cataracts?

Diabetes can be a determinant whether you get cataracts, learn more about what are cataracts from Southwest Eye Institute. Most cataracts happen because of normal changes inside the eye as you age. Around middle age, the lens may begin to change. Over time, those changes can create cloudy areas that affect vision.

Cataract risk factors can include:

  • Diabetes
  • Smoking
  • Heavy alcohol use
  • Family history of cataracts
  • Previous eye injury
  • Previous eye surgery
  • Radiation treatment
  • Long-term sun exposure
  • Steroid medications

Not every cataract develops for the same reason. That is why a comprehensive eye exam matters. Your eye doctor can examine your lens, check your vision, and determine whether cataracts are the cause of your vision change.

How Cataracts Affect Daily Life

Cataracts can make simple moments feel harder than they should. You may struggle to read small print, recognize faces in dim light, drive after sunset, or enjoy hobbies that depend on clear detail.

Some patients notice cataracts most while driving in El Paso sunlight or at night when headlights create glare. Others notice them while reading, cooking, watching television, or using a phone.

You should schedule an eye exam if vision changes begin to affect your independence, confidence, or daily routine.

How Eye Doctors Diagnose Cataracts

Slit lamp exam help to identify cataracts at Southwest Eye Institute. An eye doctor can diagnose cataracts during a comprehensive or dilated eye exam. During the exam, your doctor checks how clearly you see, examines the lens, and evaluates the overall health of your eyes.

Your visit may include:

  • Vision testing
  • Prescription check
  • Slit-lamp exam
  • Dilated eye exam
  • Eye pressure testing
  • Discussion of your symptoms and daily vision needs

Cataracts are diagnosed with a dilated eye exam. Your doctor may also check for other eye conditions that can cause similar symptoms, such as dry eye, glaucoma, diabetic eye disease, or retina concerns.

Can Cataracts Be Treated Without Surgery?

Early cataracts may not need surgery right away. Your doctor may recommend updated glasses, brighter lighting, anti-glare sunglasses, or magnifying lenses to help you manage symptoms.

However, cataracts cannot be removed with eye drops, vitamins, exercises, or lifestyle changes. Surgery is the only way to remove a cataract once it becomes visually significant. The National Eye Institute states that surgery is the only way to remove a cataract, though many people do not need surgery right away.

When Is Cataract Surgery Recommended?

Cataract surgery may be recommended when cataracts interfere with everyday activities. That may include reading, driving, working, watching television, recognizing faces, or enjoying hobbies.

During cataract surgery, the cloudy natural lens is removed and replaced with a clear artificial lens called an intraocular lens, or IOL. Southwest Eye Institute offers cataract lens options, including monofocal, toric, multifocal, trifocal, extended-depth-of-focus, and Light Adjustable Lens™ options.

Your ophthalmologist will help you understand which lens option may fit your vision needs, eye health, lifestyle, and goals.
