Normal Vision - This is called emmetropia a condition in which a person can see 20/20 without any effort. These people never need glasses to see far away but may need reading glasses around the age of forty. Although glasses are not necessary for seeing clearly, it is healthy to wear glasses to protect the eye from ultraviolet radiation. Please ask our opticians about UV protection and polarized lenses.
Far Sighted - This is called hyperopia, a condition in which a person is able to see both far and close range but has to focus harder than the normal eye to see. Only some hyperopic people need glasses, some do not. However most far sighted people struggle at the computer and with extensive reading tasks but do not realize a need for computer glasses or reading glasses. The most troubling cases are children who can see 20/20 but have to work so hard to read that they give up in school. A lifetime of poor achievement and self esteem can easily be avoided by correcting a very simple but frequently overlooked problem. It is important to have an eye exam if you do a lot of computer work. Parents should bring their children in for an eye exam by 5 years of age to screen for hyperopia.
Near Sighted - This is called myopia, a condition in which a person is able to see at close range but not in the distance without glasses. This is the simplest visual problem correct. A near sighted person can be taught behaviors that would limit an increase in prescription. See our doctor for suggestions which are appropriate for your eyes.
Power -3.00 90 degree axis
180 degree axis
So up and down the eye may have a power of -3.00 but side to side the eye has a pwer of -6. 00. This is a normal condition of uneven curvatures as in an football. Astigmatism can be corrected with glasses. Occasionally hard contact lenses maybe suggested if the prescription is too strong.
Age Related Vision Change - This is Presbyopia , a condition in which the eye loses its natural ability to focus at a close target. In a hyperopic person this can happen in the late 30’s and in most people it starts at the age of 40. Near sighted people will always be able to see up close despite their age.
Getting the proper prescription which addresses all your visual needs will help you see your best. When buying glasses first consider focusing on lenses you need to see. If you are like most people, you choose frames first. As a result, you may end up with lenses that don’t fit right in the frame. Or miss out on features that can greatly enhance comfort and eye protection. To get glasses that achieve healthy sight, both now and in the future, start by choosing your lenses.
