A pachymetry is a way for optometry professionals to measure the thickness of the cornea. This test is performed for a variety of reasons, such as to determine if the patient is a good candidate for surgery or to look for indicators of glaucoma (more on this below).

When people hear they need a prescription lens to see more clearly, most automatically think of having to wear glasses. Fortunately, contact lenses can provide the prescription patients need while being discreet. Prescription contact lenses are thin, curved lenses in the shape of small disks that rest on the tear film of a person's eyes.
Prescription contacts are a common form of eyewear that will not be noticeable when the patient wears them. Contact lenses are one of the preferred vision aids for people who would rather not have to wear glasses daily. If you are interested in prescription contacts, call us and schedule an appointment today.
Benefits of wearing prescription contacts
While some people may prefer traditional prescription glasses, others enjoy the discreet appearance of contact lenses. The reasons people may choose contacts instead of eyewear include:
- The convenience of being able to wear certain contact lenses for months at a time
- No need to constantly clean contacts like having to clean glasses
- Being able to avoid the appearance of wearing glasses
- Contacts do not become cloudy or fall off the wearer's face as eyeglasses can
What are prescription contacts?
Contact lenses are typically thin, clear, and transparent. While there are several different types of contact lenses to choose from, a common choice is gas permeable lenses. The durable plastic in this type of lens transmits oxygen to the eye. In some cases, patients can wear these lenses overnight.
Soft lenses are another popular option for most people, given the huge difference in comfort and how long people can wear them. The choice that the patient ends up wearing will depend on various factors such as the prescription they need and their preference.
How prescription contacts work
Prescription contacts work similarly to eyeglasses. They serve as lenses that focus images in the right place on the retina. The retina processes the light that comes into the eyes while the natural lens on each eye and the cornea focus light on the retina. The retina then sends the information to the brain.
When a person has nearsightedness, the light that comes into the eye is sent too far in front of the retina. When the person has farsightedness, the light is sent too far back into the retina. Other issues like astigmatism can also affect how light focuses on the retina.
The different types of prescription contact lenses
With various types of contact lenses, it is important to understand how they work. We can go over these in greater detail with the patient during a consultation.
Soft contact lenses typically consist of flexible, soft plastics that let oxygen get through to the cornea. They are more comfortable than hard lenses and are easier to adjust to.
2. Rigid gas permeable
Rigid gas permeable lenses are more resistant to the buildup of deposits and more durable. They can also provide sharper, crisper vision. They usually last longer than soft lenses and are easier to handle. However, it can take longer to adjust to them.
3. Extended wear
Extended wear contact lenses are a type of soft lens that patients can wear overnight or continuously for up to a month.
Disposable lenses are discarded after each use. They are used for a day and replaced with another set the next day. In many cases, people will need to make regular orders for these lenses.
