Must-know of various types of prescription glasses

Virtually any condition can be treated using prescription eyeglasses, which are made specifically for each patient’s visual issue. Patients need to visit an eye specialist to obtain a specific prescription that would assist them in enhancing their vision, in contrast to reading glasses sold over the counter. Even while prescription glasses cost more than reading glasses, they are frequently made with better components, including better lenses and frames. They are sturdier and are available in a variety of forms.

Single Vision

One prescription for near-sightedness or farsightedness is all that single-vision lenses will take. Most prescription and reading glasses come with single-vision lenses. Some individuals can wear their single-vision glasses both near and far, depending on their prescription. Single-vision lenses have a thicker Center for farsighted people. Single-vision lenses have bigger edges for nearsighted users. Typically, single-vision lenses are 3 to 4 mm thick. The thickness varies depending on the frame size and the chosen lens material.

Bifocals

Bifocal lenses have two separate optical powers. Simply put, they are two lenses joined together. The main part of the lens, known as the ‘carrier,’ is used for long-distance vision, while the smaller ‘segment’ bonded to it is used for reading. Bifocals are advantageous for people who require optical correction for two distinct distances, such as long distances and reading because they eliminate the need to carry two pairs of glasses. The lens’s two halves do not always have to be for long-distance and reading. Depending on the wearer’s needs, they may be the long distance at the top and intermediate distance at the bottom. These may be useful for lorry drivers who need to see their instruments at arm’s length. People who spend a lot of time at a desk may prefer an intermediate correction as the main lens in the segment with their reading power.

Multifocal Lenses

Multifocal glasses, also known as progressive glasses, are eyeglasses with multiple prescriptions in the same pair. It enables the wearer to see clearly from a distance, such as while driving or watching a movie, and from a close distance, such as when reading. It is becoming increasingly popular in Malaysia. Many professionals and business people wear multifocal glasses daily because they are extremely convenient and help them see clearly. Multifocal glasses are a pair of glasses with multiple prescriptions that cater to short-sightedness, astigmatism, and presbyopia (inability to read fine print clearly). It benefits people over 40 who have developed presbyopia (inability to see small words clearly) because it consists of reading power. Progressive lenses enable the wearer to glance between close-up items and a great distance away with ease and smooth transition.

Computer Glasses

Computer progressive glasses are intended to correct presbyopia and allow you to focus on a screen while maintaining a natural posture. They are only intended for use on your workstation. If you leave it, you must change your glasses. There are various options for those special progressive lenses. Some allow you to see the entire room clearly, while others only allow you to focus on the screen and the near-range reading distance. This makes deciding on a lens for you and the optician much easier.

Reading

Glasses for reading

Presbyopia is a disorder that most individuals encounter between the ages of 35 and 45, and reading glasses are made to correct it. Presbyopia, which affects one’s ability to see objects up close, is brought on by decreased flexibility in the eye’s lens. The specific strength of these glasses is designed to enhance the wearer’s reading vision. Bifocals are frequently used to switch between short-range and distance vision because standard reading glasses are only made to see items up close. Reading glasses, unlike prescription glasses, are not made to be worn all day. They are not intended to correct vision issues.

Photochromic lenses/transition glasses

Transition glasses are eyeglasses that appear normal indoors but automatically darken when entering brighter environments. The thought of carrying two pairs of regular sunglasses to alternate indoors and while working or walking in the sun sounds extremely tiresome. Wearing prescription eyeglasses in the sun is truly unbearable. Sometimes they get lost and are difficult to locate. However, because of the light-adaptive photochromic lenses, you no longer need to worry about whether you are indoors or outdoors because the two-in-one glasses will change themselves to fit the environment, saving you the inconvenience of constantly carrying and changing an extra pair of eyeglasses.
