To a small degree, Yes. The iris is a muscle sphincter that opens and closes to regulate the amount of light that passes through the pupil into the eye. The iris doesn't actually come in different colors; there is only a single brown pigment (for...
It means your glasses are as close to plain window glass as it is possible to be. If these glasses were prescribed for protection from strong light (tinted) or if this was part of a progressive glasses Rx (with a bifocal section at the bottom...
As a cataract and lens implant surgeon with over 30 years' experience, I would say "no." We had a femtosecond laser for doing FLACS (femto laser assisted cataract surgery) and stopped using it or recommending it to patients. We found there were no (zero) benefits...
We've all been there. You realize too late that you've slept in day-wear contacts, or left town without bringing a contact case for your lenses. No big deal, we tell ourselves. Or is it? You probably won't suffer immediate consequences from neglecting your contacts occasionally. Many...

No. As you obviously already know in asking this question, high myopia (nearsightedness) is associated with a higher overall risk of retina problems, one of the most serious being detachment. The reason for this is directly related to the cause of myopia: a larger globe (eyeball)...
No. It is important to understand that after LASIK or any lens implant surgery you still have (and will always have) a "nearsighted" eyeball, i.e. an eye that is "too big" in diameter. [This is typically the cause of the nearsightedness itself.] These procedures only adjust the focusing power at the...
A mirror is not a necessary part of measuring visual acuity. Over 100 years ago, as the science of Optometry and Ophthalmology was developing, distance visual acuity was defined as a measurement at 20 feet and beyond. [Near vision actually requires a different process, but is...
Giant Cell Arteritis, also known as Horton Disease, is an attack on the body from its own immune system that results in painful inflammation of the arteries, usually around the temples and eye area. While a soothing head rub helps most typical headaches, patients with Horton Disease...
Not usually. The eye really looks as if nothing was done. Occasionally you can see a "glint" from the lens implant if the light is right and the IOL was made of certain more reflective material. Often the biggest clue is that the cataract patient is no longer...
