How To Deal With Nearsightedness

June 27th, 2009

If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting!

A person who is nearsightedness has trouble visualizing targets in the distance, although he or she can see close at hand objects more easily. Nearsightedness is also called “myopia”.

In some cases, nearsightedness is a genetic condition due to an abnormally long eye, as calculated from front to back. As there is a longer distance between the cornea (the clear “window” that crosses the front end of the eye) and the retina (the light-sensitive bed at the back of the eye), images tend to focalise before of the retina, rather than on the retina itself.

In other instances, nearsightedness is the effect of a mismatch between the length of the eye and the ability of the eye’s lens system to focalize an image in the correct location. Again, this causes images to focus before of the retina, resulting in nearsightedness.

So, if you are shortsighted, you have to have on specs in order to correct your visual fault. The purpose of the lens arrangement within the specs is to amend the focal length of the light rays reflected from the target visual object, so that it focuses precisely on the retina. That way you will recognize a sharply focussed object in the distance. So your specs have to have a lens that counterbalances any failing in your own cornea/lens focussing system.

Being Knowledgeable Can Dramatically Quash Your Fear of LASIK Sight Surgery

June 20th, 2009

Considering the idea of getting a Lasik eye surgery procedure done is a big deal and many times people are timid in asking the imprortant questions that are going through their head.  The Lasik procedure, though widely talked about, is not discussed in detail, and people tend to fear the unknown.  I am going to discuss in this report some of the most common fears that people have, and also about what a vast majority of the people experience when they undergo a LASIK procedure.

One of the biggest and most common fears that people have when considering LASIK is the fear of pain and whether it will hurt are not. This doesn’t only go for LASIK but it also goes for any other type of operation. Since the surgeon works on a patient that is not put to sleep, this is a very widely held fear. Before the surgeon even thinks about touching your eyes, he will apply numbing drops as well as give a mild sedative to the patients so they can relax and be comfortable throughout.   Though a small pressure to the eye may be felt during the Lasik procedure, the process itself is relatively pain free.

The surgeon does use a laser in the eye to help reshape the cornea during the Lasik procedure. The many people have the concern of moving their eyeball when the laser shines in it and developing injuries and their eyeball from the effects of the LASIK laser beam. The truth of it is though is that the laser beam is only used for a period of about 10 to 15 seconds per eye, and the machine has a system that tracks your eyeball so that the laser beam only works when your eye is in the right position.

Another general fear for people contemplating a medical procedure is fear of “the scalpel”. The LASIK eye surgery procedure makes use of a very small microkeratome blade to make the incision on the eye, but this isn’t always so as some of the more recent LASIK eye surgery technology makes use of the laser to create the flap so there is no sharp object used at all.  There isn’t any real reason to be concerned about them being cut on with a scalpel in this procedure as the surgeon doesn’t use one.

A lot of people have the fear of going blind or having other serious consequences because of horror stories they might have heard about this or any other type of procedure.  Statistics taken by the government i.e. the FDA, state that there aren’t any reported cases of people becoming blind because of a LASIK procedure. The truth is that there is very little risk of any type of permanent complication arising from a LASIK surgery procedure. You have less than 1% chance of getting any type of permanent damage caused from a LASIK eye surgery procedure that is serious, and you have less than a 3% chance for any type of nonserious complications such as light halos.  It is an extremely rare occasion that somebody doesn’t have a lot better vision when going through a LASIK procedure.

If the thought of being awake and having your eyes open during the Lasik procedure bothers you, remember that you will be given a mild sedative for the procedure, and that your eyes will have numbing drops administered to them.  If the thought of actually seeing somebody’s hand approaching our eyeball is a frightening thought, take comfort in the fact that you will have drops put in your eyes it is going to black out your vision for a period of 10 or 15 seconds which is plenty of time for the procedure to be done in that eye.

This introduction has hopefully addressed the most common fears about the Lasik procedure.  For all of you out there who could benefit from this procedure, and experience the freedom of not having to wear glasses anymore, then visit your local clinic today and speak with them about any of the thoughts you might have concerning LASIK surgery.

How Do You Measure Your Pupillary Distance?

June 20th, 2009

Assessing your PD:

This measurement is the distance between the centre of your pupils that is measured in millimetres.

Opticians do not tend to give out this measurement as it encourages patients to buy their spectacles from them whereas you can buy cheap spectacles online or designer glasses at a fraction of the price online. It is ordinarily noted as 1 measurement for example 60 (60mm) but can also be shown as R 29 L 31. When written like this it is the individual distance from you right and left pupils to the centre of your nose.

When Varifocals, High Prescriptions or Prisms are ordered the measurement is commonly split individually. On the whole, if you have a single vision prescription, it will be written down as one value.

If you do not know this measurement and don’t want to measure it yourself then most online opticians will make your PD the national average (63) for men and (60) for women.

You can ask a friend or family member to calculate your PD for you:

This is the easiest method for measuring you PD. To do this, ask a friend to sit opposite you and place a ruler against your forehead so that they can read off the markings from the ruler.

Next ask your friend to close their right eye and you then look directly into their left eye. Ask your friend to slide the ruler so that the zero value is in the centre of your right pupil and to keep the ruler very steady across your forehead. Subsequently, you will need your associate to shut their own left eye and you will need to look straight into their right eye.

Your friend will subsequently take off the measurement to the centre of your left pupil. And that’s it! It really is that easy! Please see the diagram below to help you further.

Using your latest specs to measure you PD with assistance from a friend:

Check how well your eyeglasses sit on your face by putting them on and having a look. Ask your assistant to stand opposite you and verify on your lenses the position of your pupils with a non permanent marker.

You should now see two lines directly in front of you whilst you’re wearing your spectacles. Merely, remove your sunglasses and measure the distance between the two markings. And that’s it! If the ruler shows 6 cm then your pupillary distance will be termed as 60. If the measurement is 6.3cm then your PD will be 63.

If you have a varifocal measurement, then just measure across from your right eye to the centre of your nose and then again from the centre of your nose to your left eye and record the individual readings for both your left and right eyes. When buying non-prescription designer sunglasses this measurement is not applicable.
