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.

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.

3 Contact Lens Options For Presbyopia

Monday, February 28th, 2011

40 Tudor Way/North Circular Road

Tired of your eyeglasses?  Here are three contact lens options for presbyopia. Reaching the age of wisdom does not have to involve giving up wearing contact lenses.  There are more contact lenses for presbyopia than ever before; so if you haven’t tried contacts in the past few years then you may consider trying them again.

1. The most popular bifocal soft lenses are all designed around a concept called simultaneous vision.  This is where both the distance and near prescription is presented in front of the pupil at the same time.  Your brain determines which part of the lens to pay attention to and which part to ignore.

Bottom Line: Best overall satisfaction for maintaining “normal” vision.

2. If multifocal lenses aren’t for you then you can also consider monovision.  Monovision is where your dominant eye is corrected for distance while your non dominant eye is corrected for near.

Bottom Line: A good alternative if not successful with bifocal contact lenses.

3. Another option is correcting distance vision in contacts and relying on over the counter style reading glasses at near when needed.

Bottom Line: Best for those that want the best possible vision at distance.

5 Contact Lens Complications and How to Avoid Them

Monday, February 14th, 2011

Contact Lens Complications

Many patients suffer from contact lens complications that are easily avoidable. Here are some of the most common complications that contact lens wearers suffer from, and how you can avoid them.

1. Corneal Edema

If you have ever fallen asleep in your contact lenses and woke up to blurred vision for a few hours then you have experienced corneal edema.

Solution: Change contact lens material to increase oxygen transmission and have a good pair of back up eyeglasses to wear before bedtime to avoid forgetting to remove your contacts.

2. Cornea Neovascularization

Visible only by your eye doctor during your examination; it is caused by over wear of contacts.  Either wearing your lenses for too many hours or by infrequent replacement of your contacts.

Solution: Change contact lens material to increase oxygen transmission, back up eyeglasses to reduce wearing time, and replacing and caring for your contacts as recommended.

3. Contact Lens Related Red Eye

More common in over night wearers, it presents with acute redness and irritation upon waking.

Solution: Change contact lens material to increase oxygen transmission, back up eyeglasses to reduce wearing time, and replacing and caring for your contact as recommended.

4. Giant Papillary Conjunctivitis

Cause by an allergic or mechanical reaction to the tarsal conjunctiva (under the upper eyelid).  More common in over night wear, contact lens over wear, and those with allergies in general.

Solution: Responds best to daily disposable contacts.

5. Infection

Multiple factors can result in infection.  The most common risk factors are over night contact lens wear, smoking, history of previous cornea scarring, and a past episode of contact lens related red eye or giant papillary conjunctivitis.

Solution: Change contact lens material to increase oxygen transmission, back up eyeglasses to reduce wearing time, and replacing and caring for your contacts as recommended.
