Cataracts
Blurry vision, glare at night, or fading colors can quietly disrupt your daily life and, over time, lead to vision loss. At Eye MDs of Inland, Dr. Marc Shomer and Dr. Robert Gunzenhauser, UCLA-trained, board-certified ophthalmologists, provide personalized cataract care using advanced technology to help restore clear, vibrant vision.


What Are Cataracts?
Cataracts occur when the natural lens of your eye becomes cloudy, preventing light from passing clearly to the retina and affecting how you see. This clouding develops as proteins in the lens break down and clump together over time, often as part of the aging process. As cataracts progress, your vision may become blurry, dim, or less vibrant. Dr. Shomer and Dr. Gunzenhauser provide expert diagnosis and personalized cataract treatments to help you understand your condition and restore visual clarity.
Signs & Symptoms of Cataracts:
- Blurry, cloudy, or dim vision that makes everyday tasks more difficult
- Increased sensitivity to light, including glare or halos around lights
- Difficulty seeing clearly at night, especially when driving
- Colors appearing faded, dull, or slightly yellowed over time
- Double vision or ghosting in one eye
- Frequent changes in your eyeglass or contact lens prescription
- Needing brighter light for reading or close-up activities
- Reduced contrast, making it harder to distinguish objects clearly

What Causes Cataracts?
Your eye’s natural lens is meant to be clear, allowing light to pass through and focus precisely on the retina for sharp vision. Over time, the proteins within this lens can break down and clump together, leading to clouding that interferes with light transmission. While aging is the most common cause, several internal and external factors can accelerate this process.
These contributing risk factors may increase your likelihood of developing cataracts:
- Advancing age, particularly after 40
- Prolonged exposure to UV sunlight
- Smoking and excessive alcohol use
- Medical conditions such as diabetes
- Long-term use of steroid medications
- Nutritional deficiencies affecting eye health
- Certain medications, including some diuretics
- Previous eye injuries or trauma

How Are Cataracts Treated?
In the early stages, cataracts can often be managed with updated eyeglass prescriptions, improved lighting, or magnification to help you see more clearly. As the condition progresses and begins to interfere with daily activities like reading or driving, surgery becomes the most effective solution. Cataract surgery involves removing the clouded natural lens and replacing it with a clear, advanced intraocular lens (IOL) to restore sharp, functional vision.
