One wrong concept most people often commit regarding eye care is getting a contact lens right after they have their eyes examined. This is obviously wrong in the sense that the prescription is typically for eyeglasses only.
The most accurate prescription for a contact lens can only be issued after several tests and eye exams. The best thing you can do if you hate wearing eyeglasses and you want to wear contacts is to ask your doctor about your concern. They usually will schedule your appointment in addition to your eye exam.
Eye doctor use an instrument called keratometer in contact lens fitting. This device measures the curve at the front surface of your eyes. It gets the measurement of the curve and its size. They also use additional computerized measurement to get the exact size of the entire surface of your eyes.
Too steep or too loose contacts are uncomfortable to the eyes, and may result damage at the cornea. There are also many things you have to consider if you want to wear contacts. Too dry eyes for example, should not wear contacts. Some use artificial tears to moisten their eyes.
Good doctors will make sure you won’t have any problem wearing your contact lenses. Biomicroscope is a device use by eye doctors to evaluate the health of your cornea. When you wear your contacts, make sure you won’t have any difficulty on it. Consult your eye doctor regularly for your inquiries.
Trial lenses are used to evaluate how your contacts will make in your eyes at each blink you make. Some lenses may appear to fit perfectly with your eyes, and tighten up in your eyes after several hours of use.
Lastly, ask your doctor on how long you can wear a particular contacts per day, and how you should take care of it.
