When Are Kids Ready For Contacts?

Tuesday, September 24th, 2013

I am often asked by parents when are children ready to wear contacts.  Although there is no magical age when all children are ready, I generally believe that by age 10 most children are motivated enough and have the necessay dexderity to wear and care for contact lenses.  I do fit younger children, but with the understanding that parents will be willing to assist in the insertion,  removal, and cleaning (if necessary) process.

Contact Lens Benefits for Teens

Studies have suggested children have significantly better self perception about themselves, athletic performance, academic performance, and social acceptance.  Beyond better self-perception, contact lenses can also offer greater peripheral vision which can be an advantage over glasses for sports.

Caring for contact lenses is also easier than ever before.  I highly recommend daily disposable (single use) contact lenses whenever possible.  They offer the greatest comfort, convience, and lowest risk of infection compared to other contact lenses.  The prices for daily disposable lenses have come down in recent years to be less than some montly replacement lenses if you consider the price of the contact lens.

Anti-Dry Contact Lens

Thursday, June 6th, 2013

Dailies Total OneCiba has just introduced a newly designed daily disposable contact lens.  It is the first contact lens to offer water gradient technology which features a 33% water content core that increases to over 80% at the surface of the lens.  This water gradient is responsible for a silky smooth surface that lasts until the end of the day.  In clinical trials 93% of the people who tried the lens were satisfied with its comfort.

If you have dry eyes and are interested in contact lenses then this may be the perfect contact lens for you.   Gray Family Vision is one of a few exclusive Maine locations to be able to offer this exciting new contact lens!

Eyes Red?

Monday, February 25th, 2013

Why Do My Eyes Look Red

Redness in the eyes is the result of swelling or dilation of the blood vessels on the surface of the eye.

Casuses Of Red Eyes

  • blepharitis:  inflammation of the eyelid
  • conjunctivitis: allergic, bacterial, or viral
  • contact lens related problems
  • episcleritis: inflammation of the episclera
  • eye strain
  • dryness
  • glaucoma
  • injuries
  • keratitis: inflammation of the cornea
  • scleritis: inflammation of the white portion of the eye
  • toxic:  some eye drops can cause irritation
  • uveitis: inflammatory condition within the eye

Since red eye symptoms overlap with more serious infections and inflammatory conditions that can seriously affect vision an examination with your eye doctor for proper diagnosis and treatment is recommended.  If your eyes have been persistently red or the redness is accompanied by decreased vision, pain, or light sensitivity then you should be seen as soon as possible.

FDA Warning Regarding “Red Out” Eye Drops

Monday, February 18th, 2013

The FDA has issued a warning regarding the accidental ingestion of over the counter eye drops by children.  Drops with the active ingredients tetrahydrozoline, oxymetazoline, or naphazoline are affected by the warning.  These ingredients reduce redness by causing  blood vessels to narrow.  They are commonly marketed as “getting the red out”.  Accidental ingestion of these drops has caused serious events in children 5 and under.  The FDA recommends storing these drops away from small children (none of these drops currently come with child-resistant packaging), call the Poison Help Line (1-800-222-1222), and seek emergency medical care immediately if a child ingests any of these types of eye drops.

What Does 20/400 Mean

Monday, February 4th, 2013

We measure  your quality of vision at 20 feet-this is the numerator (top twenty).  The denominator (bottom 400) is a comparison to someone with standard vision.  So if you have 20/400 vision you would have to be at 20 feet to see what one with standard vision would see at 400 feet.

20/400 does not correlate to your exact prescription, it is merely a measure of your vision without (hopefully) your eyeglasses or contact lenses on.

Cholesterol Medication May Raise Cataract Risk

Wednesday, August 22nd, 2012

Cataracts are a clouding of the lens within the eye. Symptoms of cataracts include blurred vision, glare from lights, and difficulity seeing in dim illumination like night driving. Risk factors for cataracts include:

  • advancing age
  • uv exposure
  • smoking
  • diabetes
  • some meidcations such as steroids

Now, a recent study has also found a potential link between cataract development and patients taking statin medications to lower cholesterol. This is in direct opposition to what had been commonly thought.

Read On If You Have Night Vision Trouble

Friday, February 17th, 2012

Nothing is perfect, including your eye.  As light enters the eye it is altered by imperfections in the cornea, lens, vitreous, and retina.  We refer to these alterations as aberrations and the vast majority of aberrations are caused by the front surface of the eye called the cornea.

Most aberrations are typical and refractive in nature such as nearsightedness, farsightedness, and astigmatism.  These are called low order aberrations and can be compensated for with ordinary eyeglasses and contact lenses.

Other aberrations are less typical such as coma, trefoil, and spherical aberration.  These cannot be compensated for with ordinary glasses and contact lenses and are called high order aberrations.

We can now measure many of these aberrations with an instrument called an abberometer.  I find that about 10 to 20 percent of people I measure have significant nighttime higher order aberrations.  If you have night vision trouble you probably have significant higher order aberrations under low light conditions and you should be measured!

Based on these advanced measurements a pair of custom eyeglass lenses (free form/individual lenses) can be made to compensate for both your low order and higher order aberrations to improve acuity and contrast; especially in low light or nighttime conditions.  At this time we are not able to compensate for all higher order aberrations, but our abberometer has a simulation mode which can accurately predict who is able to benefit from this new technology.

January Is National Glaucoma Awareness Month

Wednesday, January 11th, 2012

Glaucoma Facts:

  • Nearly 50% of your vision can be lost without you noticing.
  • Approximately 2.2 million Americans have glaucoma.
  • About half of them don’t know they have glaucoma.
  • Glaucoma is the number one cause of preventable blindness.
  • Glaucoma can be detected during routine eye examination with your optometrist.

Get checked for glaucoma!

Improve Your Night Vision Driving

Wednesday, December 28th, 2011

Did you know that uncoated eyeglass lenses actually increase glare by reflecting light off the surface of your lenses?  The amount of reflectance varies depending on the material of lens used, but can be up to 16%.  In contrast, anti-reflective coated lenses not only decrease surface reflectance, but also internal reflectance which helps make your lenses look thinner and less visible.  They improve night vision driving and reduce eye strain while using your computer.

Anti-Reflective Coating Benefits

  • Improve night vision
  • Reduce eye strain on computer
  • Best looking lenses possible

There are differences between manufactures and the best quality anti-reflective coatings repel dirt/dust, reduce visible smudging, and offer greater scratch resistance.  Zeiss invented the process back in 1935 and I believe is still the industry leader, but Crizal, Kodak, Pentax, and Hoya are also good choices.
