Near-sighted cell discovered in retina

Researchers have discovered a cell in the retina which may control the growth of the eyeball and the cause of myopia.   It also seems that indoor light might stimulate this cell to increase the amount of nearsightedness one develops.  This contributes to the observation that kids that spend more time outdoors tend to be less nearsighted.

Having Trouble Sleeping – See Your Eye Doctor.

Most people are familiar with that blue aura glowing from tablets and laptops….it looks cool but is it harming you?  We know that this blue light (now this is blue visible light, not UV light) triggers certain things in the brain.  One is that it can disrupt sleep patterns.  So some people have taken to wearing orange lenses for the last few hours before bed…..others have just put the devices away and read a good old fashioned paper book.

Orange Lenses Can Help You Sleep

How Do I Prevent Nearsightedness?

There is a nearsighted epidemic going on in the world.  In the 1970’s about 20% of NorthAmerican and Asian 20 year olds were nearsighted.  Now it is about 40% of North American and 96% of Asian 20 year olds.

While we don’t fully understand why or how, studies seem to indicate that more time spent outdoors seems to protect against becoming nearsighted.  Studies show that about 90-120 minutes outdoors in the sun can reduce nearsightedness.  What we do know is that it is not related to amounts of upclose work, as the studies have corrected for that.  In fact, there are some schools in Taiwan that have ‘bright-light’ classrooms where the walls and ceilings are made of see through plastic and these students seem to be less nearsighted than in other schools.

So get outside!!!

2014 Optometrist of the Year Awarded to Dr. Michael Nelson

Optometrist of the Year Award 2014

Optometrist of the Year Award 2014

Manitoba Optometrist of the Year 2014 award in recognition of work on Manitoba Optometrists Therapeutic Legislation allowing Optometrists to write prescriptions to treat eye diseases like glaucoma, iritis, dry eye and infections.  This legislation which was enacted in July 2013, and is the culmination of a 30 year effort by Manitoba Optometrists to provide better access to eye care to Manitobans.  Manitobans can now receive treatment for glaucoma, iritis, infections, injuries and dry eye without having to see an Optometrist first and they be referred to an Ophthalmologist. 

Directly related to this legislation, Waverley Eye Care Centre is excited to provide a walk-in eye clinic to provide urgent eye care to Manitobans.

 

Common Eye Conditions Ages 40-60

Common Eye Conditions that may be noted in 40-60 year olds could be divided into 2 main categories:  Refractive and Ocular Health.

Refractive Include conditions that are related to your glasses presciption and include:  Myopia(nearsightedness), Hyperopia (farsightedness), Astigmatism, Presbyopia and Refractive Surgery.  The most notable of these is Presbyopia, which will affect the focusing ability and is the reason why people need bifocals or reading glasses starting in their early 40’s.

Common ocular health conditions that we will monitor for signs of in this age group include Vitreous Detachments, DIabetic Retinopathy, Glaucoma, Cataracts and Macular Degeneration.

On average eye exams every 2 years are indicated if no risk factors for eye disease are present.  However if there are risk factors for glaucoma, diabetic retinopathy or macular degeneration we may recommend more frequent visits.
