Contact Lenses For High Prescription And Astigmatism
Blurred vision. Trouble identifying objects at a distance. Sometimes even headaches, fatigue, and pain in the muscles around your eyes.
These are all common symptoms for people who suffer from astigmatism, a condition in which the cornea or lens of the eye curves at an unusual angle.
If you have astigmatism – and the only way to know for sure is to consult an optician and arrange an eye test – you are also likely to need really strong, high prescription glasses or contact lenses.
But if you don’t want to wear glasses, what is the best way to find contact lenses for high prescription and astigmatism?
High prescription contact lenses are lenses designed for people who struggle with nearsightedness, farsightedness, or astigmatism.
They correct the refractive errors in your eyes by bending light as it passes through the lens.
Refractive errors are measured in units called diopters (D).
“If you are mildly nearsighted, your lens prescription might say -2.00 D,” the online resource, All About Vision, explains.
“If you are highly myopic, it might say -8.00 D. If you are farsighted, you need ’plus’ (+) lenses, which are thicker in the centre and thinner at the edge.”
The Best Provider, According To The Experts
According to the New Grad Optometry website, one of the best providers of high prescription contact lenses is CooperVision, the major California-based company that operates across North America.
“Cooper has several lens options available to patients with high prescriptions,” the site says.
“For high emmetropes, Cooper Biofinity XR is the clear choice, with power ranges from -20.00 to +15.00.
“For those high emmetropes who are also lucky to have astigmatism, my go-to for these patients is still the Cooper Proclear Toric XR. These contact lenses range from spherical powers of +10.00 to -10.00 with cylinder from 2.25 to 5.75 in 5 degree axis steps.
“That is an impressive range of parameters without getting into the strict speciality contact lens manufacturers.”

Experts recommend that you should purchase toric lenses, which are specifically designed to treat astigmatism by curving the front surface of the lens.

These lenses come in a variety of designs, materials, and thicknesses. In some cases, an individual with astigmatism may even need more than one pair.
The reason for this is that every instance of astigmatism is distinct, so it may take more than one kind of soft toric lens, or more than one brand and design, to find the fit that offers the greatest amount of comfort and renders the greatest visual benefit.
Toric lenses also take longer to fit properly than ordinary lenses, and, unfortunately, as a result, that means that the examination and fitting process tends to cost more it does for standard lenses.
Gas Permeable Lenses
Gas permeable lenses or RGP lenses are also very useful for people with astigmatism. Gas permeable lenses facilitate oxygen flow to the eye, which helps keep your eyes moist and clear, and bolsters the cornea as it defends the eye from infection and disease.
They also tend to be less cumbersome than ordinary glasses and less susceptible to climate change, so that changes in your immediate temperature don’t fog up your lenses.
Hybrid Contact Lenses
Hybrid contact lenses are closely related to gas permeable lenses. They are large diameter lenses with a so-called ‘rigid’ gas permeable central zone, ringed by a softer zone made of a silicon material.
Hybrid lenses are specifically designed to improve the visual acuity of people with conditions such as astigmatism but are combined the physical wearing comfort of sort lensed glasses.
Finding The Best Deals
Toric lenses can be purchased from most mainstream retailers, including BioTrue and Acuvue.
But if you’re looking to sift out the very best deals, you can also check-out review sites, such as Top Ten Reviews, which offer a list of all the companies – big and small – that sell contact lenses, as well as a useful overview of their services, including the number of brands they stock and the prices they charge.
You may also want to talk to your optometrist or eye doctor in order to find out which products and retailers they think are worth investing in.
He or she is in a unique position of authority and expertise and can offer specialist guidance on how to identify the best, most affordable, and reliable contact lenses for high prescription and astigmatism.
Finally, it is worth remembering that eye conditions are often hereditary.
So if you are worried that your eyesight is getting worse, and that you may need high prescription or astigmatic contact lenses, talk to members of your family, ask them how strong the quality of their vision is, what sorts of lenses they use, and whether or not they work.
This information could be really helpful in making sure that you are protected from the worst consequences of any eye problems, such as astigmatism, that affect your immediate family members. So make sure you book an appointment with an optometrist in order to further assess your vision and which lenses would be most appropriate for you.
Ultimately, the goal is to find exactly the right set of high prescription and astigmatic contact lenses for you.
Hopefully, the information above will make that search just a little bit easier.
