So how do the lenses work? Contacts are small prescription lenses which are worn in contact with the eye, they float on the surface of the cornea; specifically on the tear film layer. Like glasses, they are made to correct refractive errors and keep ocular health maintained. They function a lot like glasses, by focusing and refracting light so that everything appears clearly.

What types are there? Contact lenses are available in many different forms, each specifically designed to meet the person’s purpose. The forms can differ from their ‘modality’, or how often someone wants to change the lens. Contacts are fitted for different needs, such as nearsightedness, astigmatism and more. They also come in various strengths (diopters). These can be identified by looking at the prescription box; you will find plus or minus signs, accompanied by numbers. These identify the shapes.

Soft contact lenses, released in 1971, completely transformed the industry. Originally, contacts were not comfortable due to the hardness and rigidity. Thomas Young was the first to wear contacts; they were secured on with wax! In 1996 daily lenses came around; and now silicone hydrogel are the current market leader. These offer much more comfort, and can be worn for longer in comparison to predecessors.

The functionality of contact lenses today makes them accessible to more people. At Spurrett Optometry we have worked hard to become the most professional provider of contact lenses Kendal has. We help people to choose the right products for their needs, ensuring they are comfortable.
