Are eye glasses addictive? I've been told, the more I wear them, the worse I'll get.

There is some truth to this. Yet, there are different kinds of glasses. Most of us wear glasses to compensate for a defect like nearsightedness or astigmatism. Unfortunately my profession called them "corrective" as they "corrected" a defect. I would prefer to say they compensated for the defect and call them compensative glasses. Those glasses tend to be addictive. During the 60's a study showed that those who wore compensative glasses required stronger glasses within a year (around 90%). On the other hand, lens therapy glasses prescribed for where we want your eyes to be rather than where they are, never become addictive. Yet, often compensative glasses need to be and should be prescribed and worn for safety and comfort. therapy

“I’ve been told Medicare doesn’t pay for a vision exam. Is that true?”
Not exactly.
Since its beginning, Medicare has covered medical eye care. While routine refractions for glasses are not covered, most patients — including those under 65 who qualify for Medicare — are found to have a medical eye condition during their exam that is eligible for Medicare coverage.
You’ve paid into Medicare through years of work, and it remains an excellent medical benefit. We accept Medicare and honor the approved fees as payment in full, with only a small non-covered portion when applicable.

My pediatrician said it is too late to treat my child’s amblyopia(lazy eye) since he is older than seven.

Not true! This is an example of old ideas dying hard. The theory is more than 200 years old. It was not true when it was imagined by leading eye doctors in arm chair discussions with no study done. It is based on the critical age theory. In the 60's Dr. Bob Sanet, then as a student at SUNY, researched the literature and found the success rate for treating amblyopia after age seven was greater than those who were treated before age seven. Numerous studies in neuroplasticity have demonstrated the critical age of seven just isn’t true. Certainly treat your child when the condition is found if before seven, but it is treatable even in adulthood.

Education and optometry have partnered for years. One example is the work of Daryl Boyd Harman, a scientist who served in the Texas school system. Through his collaboration with optometry, he brought many improvements to children's learning environments. He switched the chalkboards from high-contrast black-and-white chalk to green-and-yellow chalk, which is gentler on the eyes. He blended the artificial lighting with the natural sunlight from the windows.

What does 20/20 mean?

It is a measurement to your clarity of sight. It means what the normal person sees at 20 feet (one degree of arc), you also should see at 20 feet. The top number is always the same-the standard. The bottom number is yours. The smaller the bottom number, the more clearly you see. The number 20/200 means what the normal person can see at 200 feet, you must move up to 20 feet to see the same image. The number 20/40 means what the normal person can see at 40 feet, you must move up to 20 feet to see the same image.

Headaches, oh those headaches! Have you probably thought the headaches may be your sibling’s nagging, the beginning of a cold, or allergies? Certainly all could be a factor.

Lens therapy glasses can help reduce eyestrain in children—especially from digital devices.

The often-quoted statistic that 25% of children are failing in school tells only part of the story. It excludes the many students who struggle daily just to remain in the other 75%. It also ignores high-achieving A students who may be overworking, compensating, and silently taxing their visual system and overall health. Academic success does not always mean visual efficiency. Hidden vision problems can affect struggling students and top performers alike. Go to drhenshaw.net.

Is black all that blind people see?

No, the majority of people can see objects, they are just not as clear as they should be. Visual acuity of 20/200 is considered blind. Some people have 20/20 visual acuity but are still blind because their side vision is reduced to less than 15 degrees. See Blake Mutschler's story at drhenshaw.net.
