![]() ![]() – The majority of rigid contact lenses are fitted for patients with a distortion on the front of their eye or very high prescriptions.īut a lot of it gets down to that curve on the front of the eye. So there’s that fine line between the lenses moving too much, not enough, to just perfect. But over time, it will cut down the amount of oxygen to the eye.Īnd we’ll get more blood vessels and it’s gonna cause a lot of complications. And a tight lens feels fantastic because it doesn’t move. So, you can go to the extremes where it’s moving too much, or the other side where it’s too tight. (Leigh) – And just like a shoe, we want it to move a little bit but not too much. But it is definitely smaller and we fit them a lot differently to soft lenses. So, we need to make sure that the lenses move. And all contact lenses, when a patient blinks, the lens should move, and we have this tear pump that pumps tears out, and pulls new ones underneath. So a soft lens will cover across the coloured part of their eye onto the onto the white, whereas a rigid lens is just gonna sit within the coloured part so it’s a lot smaller. (Damon) -If we look at a soft lens has a diameter of say 14.3 millimetres, a rigid lens is anything from say, 8.6 millimetres up to 11 millimetres. What do rigid lenses look like, say a corneal lens? So we do like to replace every couple of years. And we recommend two years, ’cause as you get closer to two years, well as lenses get older, through wear and tear they will warp and change shape so they’re no longer a size 10 shoe, they’ve now moved up to 11 and a half, and the pores in the lens will block up so they will breathe less. So if you look after them well, you get the two years. (Damon)- So the majority of our patients would get two years out of their contact lens. And what’s the typical lifespan for a rigid lens? It does happen.īut if you can keep it clean, and you know it’s just some, it is an easier lens to keep clean for longer. (Damon) – Being soft lenses so much more porous and absorb more bacteria, protein, calcium from your tears and things like that, whereas a rigid lens, even though it breathes, it’s a lot harder to get a build up on the lens. Whereas soft lenses, it’s a lot harder to get a physical rub onto them with any punch to it. You can actually put a little bit more pressure on and clean them and rub them. (Damon)- Because it’s a rigid lens it’s literally firm. (Leigh) – What is it about rigids that’s easy to keep them clean? We start at the basics, and then the different options from there. ![]() And if it is a rigid lens, we’ll talk to them about the different options. (Damon) When a patient comes in, we will talk to them about what you need. So the quality of their vision cannot compare to what you get with a soft lens. But most of my rigid contact lens patients love them and their vision is sensational. You take a little bit longer to get used to it than a soft lens. They breathe more than the soft lenses, and they’re just so much healthier. So rigid lenses are easy to clean, keep clean. Most of my contact lens complications I get is with soft lenses. There’s different materials, the majority the materials we use, we really narrowed it down to one or two because they’re nice and stable and they are a high breathing material. There’s many different types of rigid contact lenses. And if it’s distorted or irregular, that is exactly what the patient needs. It really gets down to the shape on the front of their eye. And we need a rigid contact lens for certain patients, because of the shape of their eye. A rigid lens is rigid material that doesn’t flex. So you know we prefer to deal with the talk about a rigid contact lens. ‘Cause hard lenses, patients get a sense that this is something that’s not as comfortable. – Thanks Leigh, so you know in the contact lens world, there’s soft lenses, which I think the majority of the world know about, and then there’s rigid lenses.Īnd I prefer to talk about hard lenses and call them rigid lenses. ![]() (Leigh) In this video we’re covering what are hard contact lenses, and to give you more of a picture of more of an understanding of what they are. (Damon) Thank you, thank you for the invite. I’m here with contact lens specialist and owner of Ezekiel Eyes, Damon Ezekiel. ![]() Here’s the full text from the video above: ![]()
