How to Easily Convert Prescription of Glasses to Contact Lenses

Prescription of glasses and contact lenses may have some correlation but they are quite different. Furthermore, prescriptions involve typical terms that are complex to decipher. It is almost impossible for a lay man to make an understanding out of the written prescriptions. Therefore, you are always advised to visit to your eye doctor whenever you are making adjustments in your life from glasses to circle contacts. Sometimes, however, you are too stuck in life to take time out to obtain contact lens prescription. Below, we will try to explain how to convert your glasses prescription to obtain circle contacts.

How different is the Prescription of Glasses from Contacts?

Prescription of glasses is measured in Diopters sphere; represented as “D”. Diopter Sphere indicates spherical correction only. “-“(minus) signs mean correction for nearsightedness whereas a “+” (plus) sign means correction for farsightedness (hyperopia). Please note Spherical Diopters prescription does not deal with correction of Astigmatism.

Glasses sit at the distance of 12mm whereas contact lenses directly float over the cornea. This means, it is needed to be adjusted for contact lenses. Technically speaking, the strength for contact lenses should be less than that of the glasses. Fortunately enough, if the absolute value (Ignoring + or -) is less than 4.00 Diopters; the change in the prescription from glasses to contact lenses is not significant in numbers. You would only need conversions if your prescription is greater than 4.00 diopters.

By using a Vertex Conversion Chart”; you can easily convert the values to derive your prescription of contact lenses from glasses'.

Let’s take an example

Below are the Sphere Values:

OD- Oculus Dexter (right eye): -5.00

OS- Oculus Sinister (left eye): -6.00

To convert the sphere values, we start with the right eye. In this case we have “-5.00” value which we will look up for, in the middle column. Since here we have a minus sign that means a correction for nearsightedness is required, we will refer to the values mentioned in the left column i.e. “-4.75”. For the left eye it would be “-5.62”. If we keep the values same, but need to make correction for the farsightedness then we will refer to the right column. Hence the values we get will be: “+5.25 & +6.50”.

Unfortunately, converting values from vertex chart only allows you to choose for an increment of every 0.25. (0.25, 0.75, 1.00, 1.25 etc). If your prescription ends with .12, .37, .62 you need to make a contemplated decision. Make a closest match either a value up, or down. In most cases either ways should work fine. This is how a simple prescription works.

Ont the other hand, “Cylinder number” in prescription of glasses indicates correction for “Astigmatism”. Regular soft contact lenses cannot correct astigmatism but “Toric contact lenses”. We recommend seeing your eye doctor in case of medical complications as he will be better able to check your eyes and recommend a brand as per your own individual requirements & health status.

Contact Lenses could have Saved Irish Boy from Rugby Termination

By an unfortunate strike of fate, a 7 year old boy was ceased to play rugby because of the sports goggles he wears. Ryan Totten, from Colerane in county Antrim has already played rugby for his home town for 3 years. According to the experts, contact lenses could have saved him from exclusion.

According to the reports, Ryan wears sport goggles that meet EU & British safety standards to improve his vision. However, sadly, as per the IRFU rules (Irish Rugby Footbal Union) he was asked to leave the pitch due to his eyewear that bans players to continue participating in the contest. Current IRFU rules state: “In the interest of safety (of the player wearing the goggles and other players) and best practice, the wearing of glasses or goggles when participating in the contact format of rugby cannot be allowed.” The ban has left the boy embarrassed, upset & disappointed.

While the fact is unclear, what prevented the young sportsman to switch to contact lenses; optometrist & chairman of BBR Optometry, Nicholas Rumney stated that contact lenses could have been a better option. Commenting on BBC report that suggests that Ryan is too young to wear contact lenses, he explained that there is no global consensus on when to initiate contact lens wear. “There are no such age barriers”; he emphasized.

President of the British Contact Lens Association, Brian Tompkins, added: “While I’m not familiar with Ryan’s specific eye care needs, a child of his age should be able to wear contact lenses. I actually had two seven-year-olds in practice today for a contact lens review.”

Totten- the school boy pleas IRFU to change its stance because the forced prevention from playing Rugby for something he was made by God has left him broken & immensely sad.

Mr Tompkins told OT: “Any parent interested in getting contact lenses for their child, should speak to their eye care practitioner, who will be able to advise them if lenses are suitable for their child and if so, fit the appropriate lens."

Unless your child is a patient of critical eye disorders that render contact lenses incompatible, you can safely let your child wear prescription contact lenses. Don’t let the vision problems take young dreams away.
