With age, our eyes lose the ability to focus on nearby objects, which refers to a condition called presbyopia. Those who prefer the freedom of contact lenses over glasses, multifocal contact lenses have, with time, revolutionised vision correction. These lenses allow the wearer to see clearly at multiple distances, combining convenience along with functionality. However, choosing the right multifocal contact lens can feel a little overwhelming considering the vast number of available options in the market today.
Understanding Multifocal Contact Lenses
The multifocal contact lenses are mainly designed with multiple prescriptions in a single lens to correct vision at various distances—near, intermediate, and far. Unlike the traditional contact lenses that address a single vision-related issue, multifocal lenses, on the other hand, cater to the complex demands of presbyopia. They are available in different designs and materials, which makes them versatile and customisable.
Types of Multifocal Contact Lenses
Multifocal contact lenses are available in various types to suit different vision needs and preferences. Simultaneous Vision Lenses allow light of different distances to focus on the retina simultaneously and come in two designs, namely, the Concentric Ring Design that will alternate between a near zone and a distance vision zone to deliver clear central as well as peripheral vision and the Aspheric Design, transitioning smoothly from a distance to near vision, simulating the normal focus of an eye to make the visual process seamless.
Similar to bifocal or trifocal glasses, segmented lenses have distinct zones for near and distance vision and are made of rigid gas-permeable material, which will stay in place while the eye moves to allow for precise focus through the appropriate zone.
Factors to Consider When Choosing Multifocal Lenses
- Lifestyle Needs: Our daily activities play an important role in determining the best lens type. For example, if one spends long hours reading or working on a computer, then lenses with enhanced near or intermediate vision zones might be the best suited.
- Comfort and Material: Comfort is a very important factor one needs to consider when choosing the right lens to wear. Soft lenses are often preferred for their flexibility and ease of adaptation, while rigid lenses offer us sharper vision and might take longer to get used to.
- Visual Priorities: Many people prioritise distance over near vision or vice versa. Multifocal lenses can be customised to emphasise the specific visual needs of the wearer to ensure optimal satisfaction.
Fitting Process and Adaptation
Fitting multifocal lenses requires a lot of precision. During the consultation, I assess your prescription, corneal shape, and pupil size to recommend the most suitable lenses. You need to be prepared for a brief adaptation period as your eyes adjust to the new vision zones. Regular follow-ups are vital to fine-tune the fit and ensure optimal vision.
Final Words
Multifocal contact lenses have been a game changer for presbyopia, offering a seamless blend of convenience along with clarity. Understanding the different types and considering one’s unique needs helps one to make the right choice for contact lenses.
