If your vision is blurred, you may have vision problems such as myopia. Glasses can solve the problem and help you see clearly. An ophthalmologist or optician performs an in-depth eye examination to determine which type of lens is best for you. Depending on your vision problems, you may need bi-focal or progressive lenses.
How Common are Vision Problems?
About 11 million People in our country over the age of 12 need vision correction. Regular eye exams can help you control your visual health. Your doctor may prescribe glasses if necessary and immediately diagnose eye diseases.
What Vision Problems can Glasses Fix?
You may need glasses for these kind of problems such as:
Nearsightedness: You can see the things around you clearly, but things that are further away look blurry.

What are Reading Glasses?
Reading glasses are one type of eyeglass lenses. People with presbyopia often see distant objects clearly but have difficulty seeing words when reading. Reading glasses can help. You can often buy them without a prescription at pharmacies or bookstores, but you get more accurate lenses if you meet a prescription health care professional. Discussed readers are useless if left and right eyes have different recipes. Before attempting to use the reader, first consult your ophthalmologist to ensure that you can use it safely.
What is a Multifocal Lens?
If you have more than one vision problem, you may need glasses with multiple lenses. These lenses contain two or more prescriptions for vision correction. Your service provider will discuss your options with you. Options include:
- Bifocal: This lens is the most common type of multifocus. The lens is in two parts. The upper part helps you to see objects in the distance and the lower part allows you to see objects nearby. Bifocal lenses can help people over the age of 40 who suffer from presbyopia, which results in impaired ability to concentrate closely.
- Trifocal: These glasses are two-thirds bi-focal. The third part helps people who have difficulty seeing objects within access.
- Progressive: This type of lens has a rectangular lens, or continuous tilt, between different lens intensities. The lens gradually adjusts its focus when you look at it. It is like a telescope or a three-focus lens with no visible lines on the lens. Some progressive lenses cause more distortion than others. This is because more lens area is used for the transition between different types of lenses. Smaller focus area.
- Computer glasses: These versatile lenses have a special correction for people who need to focus on a computer screen. They help you avoid eye pressure.
