Sleep apnea is often discussed as a breathing and sleep disorder, but it can also affect eye health. For some Houston patients, repeated drops in oxygen during sleep may place added stress on the optic nerve, the part of the eye that sends visual information to the brain. Over time, this may increase concern for glaucoma-related nerve damage or other optic nerve changes.

Chronic dry eye can make daily life uncomfortable, especially when symptoms keep coming back despite using artificial tears. Burning, watering, redness, light sensitivity, and blurry vision can all interfere with work, reading, driving, and screen time. For many patients in Houston, dry eye symptoms are linked to meibomian gland dysfunction, a condition that affects the oil layer of the tear film.

Researchers at the University of Alabama at Birmingham (UAB) School of Optometry have found a connection between glaucoma and sleep apnea. They will present their discovery to 4,000 worldwide glaucoma specialists next month at the 2007 World Glaucoma Congress in Singapore.

Retinal problems do not always cause pain, but they can affect vision quickly if left untreated. In Houston, many patients assume that occasional floaters or blurred vision are harmless. Sometimes they are, but sudden or worsening changes can point to a retinal issue that needs prompt attention. At Houston Dry Eye Clinic, we use advanced diagnostic technology to help identify retinal concerns as early as possible.

Dry eye is not always caused by one single problem. Some patients do not make enough tears, while others make tears that evaporate too quickly because the tear film is unstable. That is why tear testing matters.

Dry eyes can be frustrating, uncomfortable, and sometimes even painful. While many people experience occasional dryness due to screen time, weather changes, or lack of sleep, not all dry eye symptoms are temporary.

Artificial tears are often the first line of defense for dry eye relief, but over time, many patients feel they become less effective. This can lead to concerns about building a resistance to eye drops or worsening eye health.

Screens are a part of everyday life for today’s children. From tablets used in classrooms to smartphones, gaming systems, and laptops at home, kids are spending more time than ever focusing on digital devices.

Corneal abrasions are small scratches on the surface of your eye, but even minor injuries can cause significant discomfort. Contact lens wearers are at higher risk, especially if lenses are worn improperly or if the eye surface is already dry or irritated. Understanding how to protect your eyes can help prevent painful injuries and long-term complications.

Color vision plays an essential role in how we perceive the world - helping us interpret traffic lights, choose ripe fruit, match clothing, and more. For most people, the eyes and brain work together seamlessly to distinguish millions of color shades. However, for those with color deficiency (commonly known as color blindness), this process doesn’t function in the same way, making certain colors difficult or even impossible to distinguish.
