Full Eye Sclera Contact Lenses
Regular contact lenses only cover your eye's cornea. Sclera contact lenses cover the entire eye, making them perfect for certain special effects, and for treating a range of eye conditions.
The term 'sclera' is probably unfamiliar to most of us, but it is simply the technical name for the white part of our eyeball. Sclera contact lenses are ones which are designed to sit on this part of the eye rather than the cornea as with a normal contact lens.
Because they are designed to sit on the white part of the eye, sclera contact lenses are much larger than regular ones. In fact, they are typically at least twice the diameter, and can in fact be so large that they cover the entire visible part of the eye!
Although this may sound daunting, the sclera is actually much less sensitive than the rest of your eyeball, which means that sclera contact lenses are actually very comfortable to wear. So if you're worried about the size of sclera contact lenses, and are wondering if it will make them uncomfortable, then you can rest assured that they'll actually feel better on your eye than normal lenses.
Some people wonder how easy sclera contact lenses are to put in and take out. Well, it depends on the size of the lens, because generally smaller lenses are easier to fit and remove. However, because they are made from a soft, flexible plastic, they are in fact very easy to use, and will not cause you any problems. If you are used to using normal contact lenses then you will have trouble adapting to sclera contact lenses.
Because they are made from a soft material, sclera contact lenses also mold to the shape of your eye, making them fit every ridge and contour perfectly. They are actually custom made for each individual eye. This is done by scanning the eye with a lazer and then manufacturing the lens to match. This ensures a perfect fit and maximum comfort.
Due to the fact that they extend well onto the white part of your eye, sclera lenses have an invisible fluid reservoir built in around their outer edge. This helps to keep the eye moist and lubricated, making them perfect for people who get dry eyes with normal contact lenses.
Generally sclera contact lenses are only used for people with rare eye conditions such as corneal irregularity or keratoconus. In some cases the results have been near miraculous. In fact it is not uncommon for patients with very poor eye sight to suddenly find themselves with almost normal vision when transferring to sclera contact lenses.
As well as being used in treating eye conditions, sclera contact lenses are also very popular in movie special effects. Because they cover a large portion of the eye, or even the entire eye, they can be used to create some fantastic effects.
The most popular type of sclera contact lenses used in special effects are those which are entirely black. This can give a creepy, hollow look to the eye socket - perfect for scary creatures! There's a huge range of theatrical contacts available in all colors, designs and styles, the perfect choice for vampires, zombies and witches.
