Solar Eclipse Safety

On August 21, 2017, millions of people in the US will experience a total or partialsolar eclipse. Day will turn to night as the moon covers the sun, temperatures will drop, and you will be able to see the amazing colors and lights of the sun's atmosphere. However, if you are going to view this eclipse, it is essential that you be prepared with the proper eye protection. Dr. Koster notes that viewing even the smallest sliver of the sun coming out from behind the moon during an eclipse could cause permantent damage to the retina of your eye, possibly resulting in blindness.

The only time it is safe to watch an eclipse without eye protection is during the phase when the moon completely blocks the sun --called totality.  Once the sun appears, it is time to put on solar filters again.  Furthermore, most of the US will not experience totality--the path for it is about 70 miles wide, passing through Oregon, Idaho, Montana, Wyoming, Nebraska, Kansas, Iowa, Missouri, Illinois, Tennessee, Georgia, and North and South Carolina.   If you are outside that path, you will only see a partial solar eclipse and need to wear eye protection the whole time.

The American Academy of Ophthalmology and the American Astronomical Society recommend these five tips for safely watching a partial solar eclipse:

  • Use specially designed solar eclipse glasses and viewers to block the sun's rays. Ordinary sunglasses are not strong enough. To date, these 4 companies have certified their solar glasses and viewers meet appropriate safety standards: Rainbow Symphony; American Paper Optics; Thousand Oaks Optical amd TSE 17
  • Inspect your solar filter beforehand and don't use if its damaged or scratched
  • Another option is to view the eclipse through #14 welder's glass
  • Use solar filters on cameral lenses, binoculars and telescopes
  • Don't use solar eclipse glasses to look through a camera, binocular or telescope. The sun could melt the filter and damage your eyes.

Enjoy this once-in-a-lifetime event, but do it safely.



NY Vision Group is pleased to announce that for the fifth year in a row, Dr. Harry Koster has been named a New York Super Doctor.  You can read more about his accomplishments in the May 14, 2017 special supplement to the New York Times.  The selection process for Super Doctors is a rigorous multi-step process. First Super Doctors creates a pool of candidates based on nominations from local physicians. Doctors may not self-nominate.  Super Doctors' research staff also contributes to the pool based on its "star search credentials".  Candidates are evaluated based on multiple indicators of peer recognition and professional achievement, including experience, professional activities, leadership positions, board certifications, honors and awards, and other outstanding achievements. Then nominees are then grouped into specialties and reviewed by a blue ribbon panel made up of the doctors who, in each specialty, received the highest scores in the nomination and evaluation steps.  Each panelist reviews and evaluates a list of nominees in their area.  Final selection to the Super Doctors list is based on the total points a doctor receives from the nominations, research and blue ribbon panel review steps. Only the highest-scoring doctors are included in the Super Doctors list.  Here is a link to his Super Doctors webpage:

 New Femtosecond Cataract Laser

In our mission to provide patients with the best possible vsion, we pride ourselves on having the most advanced technology and procedures available, combined with superior surgical skills.  To further this mission, we have acquired the new Femtosecond Cataract Laser.

This revolutionary technology allows us to use the laser to make all your cataract incisions, correct astigmatism and soften your cataract just prior to the actual cataract removal. 

Femtosecond-laser assisted cataract surgery is designed to provide the safest, most precise method for the removal of a cataract. Below are samples of the capsular opening the Femto laser makes to permit access to the cataract. The laser is approximately 10x more accurate than manually performing the same task (as demonstrated by the second set of images)
