Corneal vascularization occurs when contact lenses do not allow your eyes to breathe normally. In order for your eyes to be healthy again, you must decrease contact lens wear time and/or change to a more oxygen permeable contact lens material.
When eyelashes poke your eye…
Entropion is a condition in which your eyelid turns inwards instead of outwards. Your eyelashes then rub against the eye, causing irritation and discomfort. It can be seen in older adults, but I have also seen it in babies, as well as Asians. Entropion can eventually cause damage to the cornea, resulting in eye infectionsContinue reading “When eyelashes poke your eye…”
When your eyes don’t breathe
When the cornea does not get enough oxygen, there is corneal hypoxia. This is the most common complication of contact lens wear, especially extended-wear lenses. The cornea has no blood supply of its own, so it gets oxygen only from tears and directly from the atmosphere. Sleeping in or overwearing your contact lenses reduces theContinue reading “When your eyes don’t breathe”

If you’ve had an upper respiratory infection, such as the measles, the flu, or the common cold, you are more susceptible to viralContinue reading “An Angry, Red Eye”
When Contact Lenses Cause Problems
Did you know that sleeping in your contact lenses, over-wearing your contact lens, and not cleaning/disinfecting your contact lenses properly can cause a corneal infiltrate? Bacterial exotoxins are responsible for whitish/gray anterior stromal infiltrates in the cornea. They are usually round, well defined, and small, ranging in size from 0.1mm to 2.0mm. There are oftenContinue reading “When Contact Lenses Cause Problems”
When Contact Lenses Cause Bumps
Do you have itchy eyes and feel like there’s something in your eye? Do your contact lenses move around on your eye? Are your contact lenses uncomfortable? You might have bumps on the inside of your eyelid. These bumps represent inflammation, which can be caused by protein build-up on the contact lenses. If you haveContinue reading “When Contact Lenses Cause Bumps”
Contact Lenses Cause a Scar
Did you know that if you over-wear your contact lenses and develop a bacterial infection, a corneal scar can develop? This can permanently affect your vision.
When Contact Lenses Cause Inflammation
Sometimes contact lenses can cause inflammation of the cornea, with an accompanying bacterial infection. The white dot shown on the cornea above is an infiltrate, caused by bacterial inflammation. Symptoms can range from mild discomfort, feeling like there’s something in your eye, tearing, and redness, to severe pain, light sensitivity, and decreased vision. Corneal infiltratesContinue reading “When Contact Lenses Cause Inflammation”
