 Computer Vision Syndrome

Today we have a “welcome back to work” topic, after some Easter holidays, most of us are back in front of the computer, spending more than 6 hours a day doing well our job, but by the end of the day most of us will experience:

      • headaches
      • blurry or double vision
      • burning eyes
      • dry or /& irritated eyes
      • frequent blinking

…. It´s not the work….it´s the CVS (computer vision syndrome).

What to do?
There are some simple acts that can help to minimize the impact of “screen jobs”

  • The 20-20-20 rule: Every 20 minutes, spend 20 seconds looking at something 20 feet way.
  • Get the right light. Good lighting isn’t just flattering – it’s healthy for your eyes.

- So, keep bright lighting overhead to a minimum.
- Keep your desk lamp shining on your desk, not you.
- Try to keep window light off to the side, rather than in front or behind you. Search the position of the computer screen to reduce reflections from windows or       overhead lights.Adjust the screen settings to where they are comfortable
- Use blinds and get a glare screen.

  • Monitor your monitor. Keep it at least 20 inches from your eyes. Centre should be about 4 to 6 inches below your eyes. Also, make sure it’s big enough and with just the right brightness and contrast.
  • Wear computer specs. Your doctor can prescribe a pair of glasses just for seeing the computer screen well. If necessary, wear the appropriate corrective lenses while at the computer.
  • Talk to your doc. about this problem, the best is prevent ; ) and don´t forget to keep blinking. It washes your eyes in naturally therapeutic tears.

mischabarton-d475acd3993c3eea46c1ac30b4bbfe17_hWhat we do when we don´t need our prescription glasses any more ? Where we throw them? Some organisms are taking action: collecting , cleaning and repairing used prescription eyeglasses for delivery to the populations affected by vision problems and unable to access to eye care services . An ecological and humane way to reuse your glasses helping millions of people with no resources.

One Sight, Lions Club International and New Eyes for the Need are some of these organizations that are engaged in collecting and recycling used eyeglasses in the world

Not only caring citizens but also optical companies that have discontinued or stopped using certain models of frames and lenses can work with these projects.

How to do it ? Bringing your pair to the establishments or by registering in programs which assist eyeglass recycling or just send them to the headquarters of the organizations just as simple as that, and remember: All of them are welcome, sunglasses, reading, prescription glasses, outdated frames and lenses. If any can not be recovered, it is the organization which is responsible for removing them properly, always using organic methods.

Once agencies have received the glasses, they are in charge of cleaning, repair and especially classify every one, depending on the graduation or usefulness for onward shipment to countries in process of developing.

According to the World Health Organization 153 million people worldwide suffer from some uncorrected vision problem , this is the start of the main cause of decreased visual acuity and blindness. In addition, 12 % of cases of childhood blindness could be avoided by the use of glasses .However, millions of people lack access to diagnostic services and poor situations difficult the purchase of glasses which ends up impacting the daily life quality of millions. Reuse of glasses is also a great way to contribute to the development of a country.

Following the local laws of each country of destination , the agencies are responsible for eye exams and make available for free requiring glasses those ones who most need a pair.

Recycling your glasses can be a great way to contribute to the development of several countries: 80 % of the information we receive comes through view, so it is important to help as much people without resources as we can. 

An EcoFriendly way to contribute to reduction of visual problems and favour the education and social integration of disadvantaged people.

So from now on… give your glasses and share your view!!

Do you really understand your optical prescription?

It has never been so easy!!

Optical Prescription Glasses

An optical prescription may vary depending on the formatting and the country we are. However, they are more or less universal . Most doctors use a similar process to graduate your vision and create the prescription. It is necessary that your report is less than two years old and your optician or ophthalmologist is required to provide you with a copy of your graduation without any extra charge .

The optical prescription is divided into right (OD) and left eye (OS) and now we’re going to reveal all its secrets.

The sphere ( Sph / EsF )

Specifies the force that your lenses need to have for correcting your vision: a positive sign (+ ) indicates that we need to correct farsightedness ( hyperopia = difficulty focusing on nearby objects ) and a negative sign (-) means that you have to correct nearsightedness (myopia = trouble focus on distant objects). The numerical values indicates the number of correction you need for each problem , the higher the number, the thicker your lenses.

The cylinder (CYL / CYL )

Indicates necessary dioptres to correct astigmatism . We can find this in your optical prescription usually named as Cylinder CYL or Clylinder . The cylinder can have a positive or a negative sign (never mixed). The CYL also comes along with a value for the Axis or Axis (indicates the inclination of the eye) a number between 1 and 180. If these values do not appear in your optical prescription , just leave spaces empty.

The sum (near / ADD)

It is very common to use glasses for reading, it´s well known as near vision (aka reading glasses ) for that we use multi focal lenses (progressive/bifocal ) .

We use the parameter: Sphere or spherical near power . This value can also be positive or negative. The Adding value is obtained as a result of this subtraction :

Adding = sphere far – near sphere

The pupillary distance ( PD)

The pupillary distance (PD ) is the distance from the center of the pupil (black circle) in one eye to the center of the pupil in the other. This measure is essential to focus the power of lenses and if it is not written in the recipe , you can ask your optician this information, ask for help from a friend or do it yourself with the help of a mirror and a ruler.

Here ‘s how:

  1. Place the millimetre ruler on the bridge of the nose.

  2. Ask someone who makes himself a half meters away in front of you and measure with ruler the distance between the centres of the pupils (the black circle in your eyes) .

My pupillary distance

Here you have a rough guide to average values for orientation:

Adults – typical values move between this range: from mm 56mm  to 66mm.

Children – Typical children’s values usually range: from 41 mm to 55 mm.

Now that you know how to make it…go for it : )
