Top 5 Smartphone Apps for Your Eyes

Thursday, August 5th, 2010

Here at La Jolla LASIK Institute we like to stay on top of the most cutting-edge technology in the ophthalmological world.  One breakthrough trend we’ve noticed lately: vision-related apps for smartphones.  From vision tests to optical illusions, these applications are increasingly growing in popularity in the smartphone community.  While we can’t promise that any of these are medically accurate, we can promise that they’re entertaining!  Here is a top five list of various vision apps that we’ve found to be the most diverse and interesting:

  1. NETRA App (Not yet priced: estimated $1.99) – Although this app is still a prototype, it looks extremely promising.  Developed at MIT for the Android, NETRA has gained a lot of publicity recently.  After downloading the app, the user will attach an inexpensive ($2) lens to the screen of their smartphone and hold it up to their eye.  The user will align patterns presented in the lens by pushing buttons on the phone, which is repeated four times (one for each eye’s axis).  Once this is complete, the app delivers the user’s eyewear prescription.  Keep an eye out for this one, folks – we can’t wait for this to arrive on the market.  At first we were skeptical that a product used at near could accurately test for a person’s distance prescription, but the data on this one looks promising.  If it works, it could be a great solution for rapidly screening large groups of indigent people around the world.  We look forward to testing it out on medical missions and at health fairs when it’s available.
  2. Amazing Illusions: Fun Optical Puzzles ($0.99) – This app holds an excellent collection of optical illusions and puzzles that are both entertaining and stimulating.  The illusions are mostly presented in a Q&A format so unless you pick the “cheat” option (don’t get tempted!) you can test your mental abilities and share them with your friends.  Apparently there is a warning not to use this on your pets!!??  So, please don’t mesmerize little Fifi.
  3. Eye Exercises – Daily Program ($0.99) – We list this one because you’re bound to find it and ask about it.  There is only ONE diagnosis, convergence insufficiency, that has ever proven to benefit from “eye exercises.”  AND standard convergence insufficiency treatment requires one piece of equipment — an ordinary pencil!  We bet you can get a pencil cheaper than $0.99, but if you can’t, here’s an app for you.   This app has some other stuff on it too, so check it out if you’re curious.
  4. PseudoChromatic ColorTest (Free) – This app is designed specifically to assess color vision deficiency.  It delivers the user a series of images where a colored number is presented in the middle of another color – this is known as the Ishihara Color Test.  This app also great fun because it provides information on the different types of color perception, statistics on people who experience color deficiency, and the ways in which color deficiency is passed on genetically.
  5. EyeXam (Free) – Since NETRA hasn’t quite come out yet, this is the next best thing.  EyeXam helps users evaluate their vision with an eye chart using the highest performance method.  There are tests for color perception, eye dominance, and astigmatism.  Its revenue model seems to be to be a paid directory for local eye doctors, so check it out and tell us if it’s good enough for us to be a listed eye clinic.

These apps are a very entertaining way to engage with your eyesight – please let us know if you have tried out any of them and what you think.   Intuitively obvious disclaimer:  no app is a substitute for your Eye MD examining your eyes.  But the next time you’re here at La Jolla LASIK Institute seeing Dr. Nahl in preparation for your super-vision San Diego LASIK eye surgery, you can compare vision apps!  Enjoy.

8 Tips for Healthy Eyes

Monday, August 2nd, 2010

Here at La Jolla LASIK we are devoted to excellent vision and healthy eyes.  While LASIK patients enjoy exceptional vision after their surgery, they need to make sure they devote time and effort to maintaining good eye health in order to extend the positive effects of LASIK for the rest of their lives.  Here are a few tips that will guide you in keeping your eye health in prime condition:

1)    Say No to Guns: Keeping any sort of firearm around the house poses an immediate danger to you and your loved ones’ lives and eyes.  Low-velocity ballistic weapons like BB guns, which are often thought of as toys, are extremely dangerous – every year there are about 20,000 cases of eye injuries and resulting visual damage in young children.  Pellet gun eye injuries are often blinding.  And, I’ve previously written about the circumstances in which a favorite man-sport becomes blinding in this post:  Paintball.

2)    Goggle up: According to everydayhealth.com, more than 1 million people suffer eye injuries in the US each year and 90% could have been avoided if they wore protective eyewear.  So, make sure you wear appropriate safety eyewear next time you are hammering something into your wall, cleaning with bleach, doing a lab experiment, operating heavy machinery or playing sports like racquetball or basketball. While goggles aren’t quite as fashionable as sunglasses, we can guarantee that the few minutes of dorkiness are well worth a lifetime of protected eyesight.  And who knows, maybe you’ll find a pair of bad-ass tinted safety goggles to wear.

3)    Protect yourself from the sun: Here in San Diego, everyone has seen someone with a growth on the white of the eye.  This growth, called a pingueculum if it’s small, or called a pterygium if it crawls onto the clear part of the eye, comes from too much sun exposure.  Here in San Diego, you’ll see it the most in blue-eyed surfers, and anyone who spends all day in the sun.  Be sure to wear UV-protective eyewear whenever you’re outside or driving to prevent pingueculum, pterygium, and other eye disorders.  Good thing shades are timelessly fashionable – look chic and keep your eyes healthy!

4)    Be kind to your hard-working eyes: If you work at a desk in front of a computer all day, there are certain things you can do to make the strain a little less harmful to your eyes.  Make sure your workplace has good lighting, take visual breaks frequently by looking out the window at a distant target, and keep eye drops handy if your eyes start to burn or feel dry.  The mildest drops are “artificial tears without preservative.”  Avoid “get the red out” drops, as they are vasoconstrictors and when they are used chronically they make eyes even redder than before from reflex vasodilation.  Artificial tears without preservatives are so neutral that you can use them as often as you like!

5)    Be diligent about eye infections: Infectious conjunctivitis, or pink eye, is an extremely common infection that also may be extremely contagious!  If you suspect that you have a bacterial eye infection (symptoms include eye pain, green or yellow discharge, excess sensitivity to light) then see your ophthalmologist right away.  “Epidemic Keratoconjunctivitis,” or classic “pink eye,” a bright red eye without discharge, is usually a viral infection, and spreads like wildfire – from one eye to the other, and from one person to another.  Give your ophthalmologist a call, and take precautions to prevent contaminating those around you.  Despite any discomfort, keep your hands away from your face; wash your hands immediately after touching your face or eyes; don’t share washcloths, towels, or pillowcases; and wash and sanitize your hands often.  Your loved ones will be grateful for your precautions.

6)    See an ophthalmologist immediately if you see a sudden shower of black floating spots. A sudden shower of black spots can be the sign of a new retinal hole or even a new retinal detachment, and with prompt treatment within hours, can prevent visual loss.

7)    Nutrition:  The old “carrots are good for your eyes” saying came from the days when produce was not available year round, and vitamin deficiencies were much more common.  A normal, well-balanced diet including plenty of fresh fruits and vegetables will keep you out of trouble.  You can print out what each person in your family should be eating at:  www.mypyramid.gov

8)    Go to your doctor for yearly eye exams: Annual eye exams are one of the easiest ways to maintain your eye health.  If you visit your doctor on a regular basis, problems and disease can be detected in their early stages and most likely remedied.

Protect your peepers, follow these tips and your eyes will be grateful and working well in the long run!
