Eye problems are common problems associated with reduced vision, among other problems like blurry vision, which may result from myopia. The use of eyeglasses helps people with certain conditions correct their problems, making them see clearly.
The healthcare professional for treating eye problems is referred to as an optometrist and usually performs eye exams to figure out the needed eyeglasses or lenses to correct specific conditions. Eyeglasses correct vision problems by increasing how particular things can be seen from a distance. It is estimated that over 11 million Americans over 12 have eye problems requiring prompt medical care.
To ensure complete vision health, individuals must have regular eye exams to help them stay on top of their vision health. Some common problems that can be corrected using eyeglasses include Nearsightedness, also known as myopia, farsightedness, also referred to as hyperopia, astigmatism and presbyopia, which is the ability to lose focus on near objects.
The types of glasses to use
The healthcare provider determines the best type of glasses to use based on the eye exam results. Some of the standard lenses that can be used to cure common eye problems include a concave lens, which is curved inwards for the correction of Nearsightedness. This convex lens is curved outwards to correct farsightedness, cylindrical-shaped lenses to cure stigmatization, and bifocal or multifocal lenses to treat presbyopia. There are different types of lenses which can be used by individuals with various problems related to focusing on objects far or close, including single vision lenses, which can correct myopia, presbyopia, and hyperopia.
What are glasses for reading?
Most people with reading problems use single vision glasses, also called nerd glasses. Reading glasses can correct presbyopia which is seeing distant objects clearly with challenges with seeing things close by or when reading. The problem can be Cured using reading glasses which can be bought over the counter or bought under the prescription of a medical practitioner. In some cases, the eyes can have different conditions, which may require other prescriptions. The main reason is to visit healthcare practitioners to get a prescription on which glasses to buy. There is also the option of buying glasses online, but regardless of the choice or place of purchase, individuals should have a doctor or healthcare prescription before making any purchase.
In some instances, individuals can have more than one vision problem, which needs the use of multifocal lenses to correct the issues. Multifocal lenses use more than a single prescription correcting mechanism, which can be discussed with the patient and the healthcare provider. The different types of multifocal lenses include;
Bifocals-these are particular types of lenses with two sections. The upper part can see things at a distance, while the lower parts are used to see things close. Individuals mostly use glasses over 40 with presbyopia, resulting in a reduced ability to focus.
Trifocals- These are a type of multifocal lenses with three sections. The additional third section helps the users see things and objects at arm’s length.
Progressive lenses- The lenses are designed with an inclined lens which helps by providing different lens power. The progressive lens allows for advanced focus as individuals look closer through them but functions like bifocals or trifocals. Progressive lenses cause more distortion compared to other types of multifocal and single focal lenses because the area between the les allows for additional transformation between the lenses with a smaller focal size.
Computer glasses- Computer glasses are multifocal lenses mainly used by individuals who need increased focus while using computers and can be used to help avoid eye strain.
