Minus On The Contact Lens?
Hello, I have a question. Yesterday I bought a soft lens, -3.00 (right) and -2.25 (left). When I used it it was a bit heavy on the left and it turned out that after I got home I checked the doctor’s prescription for glasses: -3.25 and cylinder 0.5 (right) and -2.00 (left). Do I have to buy more contact lenses according to the size of the glasses? Or only buy sizes -2.00 so that I use sizes -3.00 and -2.00?
Thank you for asking HealthReplies.com.
Minus eye or known as myopia in medical terms is a visual disorder in which the eye cannot focus to see distant objects. The severity of the minus disorders is divided into 3 grades, namely low, medium and severe levels. The low level is assessed if the minus is minus 0.5 to 3 diopters, the medium level is minus 3 to 6 diopters, while the heavy is minus above 6 diopters. The therapy of choice with minus eye conditions is to use glasses or contact lenses according to the disorder.
Meanwhile, cylindrical eye, also known as astigmatism, is a condition in which the eye is unable to focus, it is blurry whether objects are near or far. In addition, people with cylinder eyes also complain that it is difficult to see small writing. As with minus eyes, the therapy that can be done is to use glasses with cylindrical lenses.
In your case where the minus eye and the cylinder eye are at the same time it is necessary to use glasses with a combination lens for the minus eye and the cylinder eye of the appropriate size. If the lenses used are insufficient or inappropriate, the eye cannot focus optimally, causing certain complaints such as dizziness, headaches, nausea and fatigue and eye strain. That way you can't do your activities optimally.
