Fitting contact lenses is NOT a precise science!Its part science and part finnesse!ONLY an eye doc can determine this. As you’ve read ill-fitting contact lenses can be uncomfortable and long term damage to the cornea can ensue. Alot of patients are wearing improperly fitted contact lenses. Its different than the regular eye exam. You need to get an eye exam and a contact lens fitting. THey are two separate exams and typically its best to get both done. The eye doc will take a look at your eye and surrounding tissues to make sure you are a candidate for cl wear. THen they will take measurments of your cornea and place a trial cl on to check for fit. THere may be other tests used as well depending on your age. Eye docs can now fit successfully multifocal contact lenses which will allow the eye to see at all distances. THe technology in vision science has come quite far and this technology is amazing.I wear custom multifocal rgp lenses and they are amazing. They allow me to see at all distances comfortably and the vision is hyper clear.

I can interpret your question in one of two ways, so I will answer them both ways.Using contact lenses without a prescription by wearing prescription contact lenses you obtain online without an official prescription from an eye doctor: many patients do this and then see their eye doctor when they have a problem. Unless you are checked regularly, you cannot ensure that the fit is proper and that could lead to problems with the cornea such as contact lens overwear syndrome and ulcers. The eyes can naturally change a little over time and just ordering the same lenses over and over again can result in an improper fit and this can be dangerous.Using contact lenses that do not actually have a prescription, as in cosmetic contact lenses for the purpose of changing the eye color or for a novelty look for Halloween for example. This is potentially even more dangerous because many of these cosmetic lenses are not regulated. They are sold through novelty stores. They may not be sterilized. They may not have expiration dates. They may be contaminated with serious pathogens (several cases have been reported). I have treated some of these which have led to serious fungal infections requiring a corneal transplant to save the vision. Bad idea.Hopefully that answered your question.

The process depends on your glasses prescription.Some prescriptions don’t require a conversion at all.Some prescriptions require a simple conversion.Some prescriptions require a complex conversion.Some prescriptions require some conversion and some rounding.Some prescriptions cannot be converted at all.This answer would be insanely lengthy if I described the entire process here, but I have written several articles explain the process for every possible scenario on my contact lens blog Contacts Advice.Give them a read if you’re interested in learning more.Converting Your Glasses Prescription to a Contact Lens PrescriptionConverting Eyeglass Prescription To Contact Lens3 Ways to Convert Your Glasses Prescription to Contact LensesContact Lens Prescription VS Glasses PrescriptionVertex Conversion Charts for Sphere and Cylinder CombinationsConverting a Glasses Prescription To Contact Lenses TUTORIAL – Part 1Converting a Glasses Prescription To Contact Lenses TUTORIAL – Part 2Converting a Glasses Prescription To Contact Lenses TUTORIAL – Part 3Converting a Glasses Prescription To Contact Lenses TUTORIAL – Part 4Keep in mind that converting your prescription yourself is not sufficient to order contact lenses online. In the U.S, you are required to provide your up-to-date contact lens prescription before you can be sold contact lenses.Also, I do not recommend or condone ordering contact lenses without a valid prescription.

In theory, if a certain contact lens is prescribed, that means that that particular lens has been fitted on you and a follow up was performed to ensure that there is a good fit and it provides good vision and the eye tolerates it well as seen in a magnified view.Just because one brand in one material suits you well does not mean that any material will suit you just as well when all these details are evaluated. There are different characteristics between the material and the physical shape of each particular contact lens.That is absurd that there is a fear companies pay kickbacks to doctors to prescribe their brand. You pay the eye doctor for professional services to use their knowledge to be able to figure out a lens Rx that works well for you. They can’t prescribe a lens that isn’t made so must use lenses that are on the market. The companies do market their products to the practitioners so that they are aware of the latest developments available.I can guarantee you that if a particular lens does not work well and I get bad feedback from the times I try to fit it that I will not use that lens, even if the company gave me a pen and a scratch paper pad to use or provided a meal at a restaurant for a lecture I attended to accumulate continuing education points that are required for state licensure or because they stopped in with boxes of pizza when they spoke with us about their products when I was in optometry school. If there are any other “kickbacks” then I am really missing out.In general, the latest contact lens technologies have better comfort and better oxygen transmissability which is healthier to wear and are priced higher than the older technology and inferior products as with just about any product in any other industry. The motivation is not to trick you to spend more money but to get a good result and avoid running into problems in the future from your contact lens use.

When contact lenses first came out, they were a lot more complicated and a lot less healthy for you. Each lens had to be custom made for each eye, then often sent back for modifications based on the doctors evaluation of fit and vision. When I was in optometry school (‘98-‘02), we had about 10x more hours of learning /training in fitting hard, PPMA, RGPs than we did in fitting soft contacts. When I stared out in 2002, I saw about 2 of these hard contact patients per week, now it’s about 1 per year. I don’t know if they even still teach hard contact fitting in optometry school.Even though contacts are now a lot safer, and easier to fit, they are not perfect and not (quite) 1-size-fits-all. I have seen an uncountable number of patients with contact lens complications, from Giant Papillary Conjunctivitis (GPC) to Corneal Ulcers. Most of these are from the patients not following the doctors or lens manufacturers recommendations. Can you imagine how this number would skyrocket if they didn’t even need a Dr. to direct and monitor them? We often will switch the patient to a different lens at the follow up or yearly exam, even if they think they are ok. We can see complications in the early phase before they become major sight-threatening issues.Also, contact lens technology is always changing. Not too long ago, most people wore the low-oxygen lenses. As the high-oxygen ones become more popular, and showed a lot less complications compared to the low-oxygen ones, we were able to recommend this new technology to patients with neovascularization, for example. This is a sign of oxygen deprivation and can lead to corneal edema (swelling), bacterial conjunctivitis, and corneal ulcers, which are very painful and can lead to permanent vision loss. Every week or so, I see a patient who’s vision is permanently reduced (although usually minimaly) due to a prior contact lens complication, usually a central corneal ulcer. Most of the severe complications are from people who were able to get contacts without a Drs prescription, usually colored, or from Mexico.I know that most of you are thinking, “Well, I’ve worn the same brand of contacts for years and never had a problem, so why do I have to pay for a Dr to give me permission to buy more?” Well people’s eyes DO change. The lens that was working may no longer be the best, clearest, safest lens for you.

It won’t be dangerous, but you should be aware that they are probably both made to correct your eyesight without anything already on it. So if you wear both the contacts and the sunglasses, you might not see as well and life might get pretty tiring, because you are now walking around with an overcorrection. Which can be dangerous if you are not aware that you don’t see as much as you should.Consult your optometrist if you are not sure if the sunglasses are made to wear with the lenses or not. If you have a normal need for glasses, ie no severe astigmatism, the best bet is that they are meant to be worn separately.

It depends on how different the vision in your eyes is. I’ve always had a 0.25 difference between the prescriptions for my left and right eyes. Ever since I started wearing contacts, my doctor has been prescribing the same strength lenses for both eyes because I wear monthly lenses and tend to get the right and left lens mixed up if they are different, and I don’t even really notice that one eye has slightly worse vision than the other. This hasn’t really caused me headaches or made my vision deteriorate at a different rate in on eye than the other, or caused any other ill effects. Like I said, though, the prescription my “bad” eye should have is pretty close to that of my “good” eye, so someone with a larger difference in prescriptions might experience more issues than I do.

yes, it’s available commercially in USA now, it’s a coloured contact lens under the sun.

Can I use my glasses prescription for contact lenses? The simple answer to this question is no \u2013 you cannot and should not use your glasses prescription to try to calculate your contact lens prescription.

Procedure. 1) Algebraically add the cylinder power to the sphere power to arrive at the new sphere power. 2) Change the sign of the cylinder power. 3) Add or subtract 90 from the axis. Example 1\u2014 Transpose the following prescription. +2.00 \u2013 2.50 x 105. -.50 +2.50 x 15. +1.00 + 3.00 x 35. +4.00 \u2013 3.00 x 125.

There is a separate prescription for your right eye and your left eye. Most of the time, OD and OS are indicated on the left of your prescription and the following numbers show each eye's specific needs. Some glasses prescriptions also include additional numbers such as: Prism: measured in prismatic diopter (p.d.).

Contact lens prescriptions and eyeglass prescriptions are not the same. They are signNowly different because eyeglass lenses are positioned approximately 12 millimeters from your eyes, whereas contact lenses rest directly on the surface of your eyes.

Unfortunately not. Your eyeglass prescription only has the power part of the contact lens prescription. In addition to the power the proper base curve (BC) and diameter (DIA) are needed to order contact lenses. Contact lenses come in different sizes and must be fit to your eye by an Optometrist or Ophthalmologist.
