Why Some Patients Are Hard-to-Fit For Contact Lenses And How We Have You Covered

Contact Lenses, West Vision

An estimated 140 million people globally are wearing contact lenses to correct their vision. It’s no wonder they are so popular: Contact lenses are a highly convenient solution to vision correction.

If you enjoy playing sports, you don’t need to worry about glasses getting in the way of your active lifestyle. When you are wearing contact lenses, you can just wear regular sunglasses as and when required. You also don’t need to carry more than one pair of glasses with you.

Contacts aren’t affected by rain, nor do you need to worry about lens glare in photos.

Your contacts won’t steam up when you open the dishwasher or walk into a steamy bathroom.

Contacts won’t get in the way of a kiss or fall off on a rollercoaster. Most of the time, you can just pop your lenses in and forget you are even wearing them.

There are many benefits to wearing contacts, but for some patients they just don’t seem to work. It can be disheartening when you would like the flexibility of contact lenses but your eyes don’t want to play ball.

If this sounds like you, Dr. West would like to help.

What could make me a hard-to-fit patient?

There are multiple reasons why you may be classed as hard-to-fit as a potential candidate for wearing contact lenses. Some are to do with disease of the eye, some to do with the shape of your eye, and others to do with the type of vision correction you require. Most issues are about discomfort caused by wearing lenses or instability of the lenses.


A few of the major reasons that fitting you with contacts could be challenging are:

Dry eyes - dry eye disease can either occur on its own or as a result of wearing contact lenses. Dry eye can be painful and even result in damage to your cornea.

Astigmatism - a common condition in which the shape of your eye is off-circular. The irregular shape of the cornea means that light is refracted by varying degrees depending on the angle it enters the eye, so vision is blurry. The irregular shape of the eye can be challenging to accommodate with lenses.

Keratoconus or Pellucid Marginal Degeneration - both conditions cause progressive thinning of the cornea. This can cause similar issues to astigmatism in that the shape of the cornea may become irregular.

Presbyopia - this is normal age-related changes to the eye that result in difficulties seeing small print as you age. It is caused by a loss of elasticity in the eye surface.

If you fall into one of these categories, we can still help you find a good contact lens fit

Even if you have tried contact lenses in the past and became one of the up to 50% of people who stop using them within the first three years due to discomfort, we can still help you find the lenses that will work for your eyes.

Scleral lenses are so called because they are designed to rest not just over the cornea, but on the whites of your eyes - known as the sclera. They are much wider in diameter than traditional contact lenses, and there are many benefits.

Effectively, the scleral lenses replace the corneal surface with a smooth, even, optically perfect surface to improve your vision. In addition, the issue of dry eyes caused by contact lens use is eliminated, as the gap between the corneal surface and the scleral lens acts as a fluid reservoir, maintaining optimum moisture levels and preventing friction.

What type of scleral lenses will work for me?

Generally, the size of the problem is reflected in the size of the lens. The more mild the defect in the cornea, the smaller a lens can be but still provide great results. It is best to try the smallest possible scleral lenses to correct your problem, as the larger the lens the higher the cost and implications for looking after the lenses.


At West Vision, we are passionate about helping you find the right contact lens solution, no matter your vision problems or why you may have been diagnosed with hard-to-fit eyes. We believe that if you want to try contacts, we can make it work for you, with a little trial and error.
