Eye examinations for getting contact lenses have special tests as well as measurements that are generally not included in routine eye exams for glasses. If you already have contact lenses or wish to switch to them instead of glasses, you need to schedule an appointment with a good doctor to get your prescription updated. When the appointment for the exam is scheduled, your doctor gets time to perform all the tests needed so that you can get the proper contact lenses fitted and your prescription updated.
What should you expect from contact lens exams?
During the contact lens exams, doctors will test the visual acuity of the patient with an eye chart. Besides this, a number of tests will be performed for determining the health of your eye and whether you need to wear prescription glasses for the correction of any kind of refractory error. You get other information so that the correct eye lenses can be given to you or if you already have contact lenses, they need to be evaluated and changed.
General questions about your contact lenses
Your doctor might ask you some general questions about your contact lenses relating to your preferences and lifestyle. For instance, you may wish to change the color of your eye with contact lenses or are more interested to choose contact lenses that can be disposed of away daily. In some cases, you might wish to choose contact lenses you can wear throughout the night.
Rigid gas permeable contact lenses
Your doctor might recommend you to take rigid gas permeable contact lenses known as GP or RGP in the market. They offer you sharper vision over soft contact lenses. You might be asked to correct problems in vision with age, and here you can choose contact lenses for the purpose. After the age of 40 years, one suffers from a vision condition called presbyopia that reduces the ability of a person to read the small fine print or even focus on objects that are nearby.
In order to correct this condition of presbyopia, your doctor provides you with the option of contact lenses that are multi-focal or bifocal. There is another alternative called monovision. This is a special type of contact lens where the lens fitted on one eye is for distance vision, and the lens fitted on the other eye is for near vision.
There are no uniform contact lenses for everyone
Note that when you go for contact lenses examinations, there is never a single product that fits everyone. Measurements need to be taken during the exams. They must be accurate, or else you will face a lot of discomfort in the eye.
During contact lens exams, measurements of the cornea, pupil, and iris are taken by the doctor. The doctor ensures you get contact lenses that are clean, safe, and comfortable for your vision. Like prescription glasses, you need to care for them well and regular check-up with your doctor so that you face no hassles in the future with vision at all!
