Glasses versus Contact Lenses: What's the difference?
For many individuals who require vision correction, the choice between glasses or contact lenses is a matter of personal preference. While both options offer effective ways to correct vision, there are differences between the two, particularly when it comes to prescription requirements.
So, is a glasses prescription the same as a contact lens prescription? The answer is no. While similar, there are some key differences that must be taken into account when obtaining a prescription for contact lenses.
Differences between a Glasses Prescription and a Contact Lens Prescription
A glasses prescription is defined as the measurement of the corrective power required to correct vision problems such as myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism. This prescription is given in simple diopters units, and it refers only to the optical power requirements necessary for the glasses' lenses.
Alternatively, a contact lens prescription is a more complicated process. Specific measurements are taken of the curvature of the eyes, the size and shape of the cornea, and the amount of tears produced in the eyes. These measurements are then taken into account when determining the contact lens prescription. A contact lens prescription also includes a base curve and diameter to ensure proper fit and comfort.
Benefits of Glasses
Glasses remain the most common form of corrective lenses. There are several advantages to wearing glasses over contact lenses, including:
Easy Paired with Accessories
Since glasses require no direct contact with the eyes, they can be quickly and easily paired with accessories such as eye protection, headphones, hats, and jewelry.
Protection
Glasses provide a necessary layer of protection for the eyes against airborne particles, UV radiation, and other environmental hazards.
Affordability
Compared to most contact lenses, glasses offer a more affordable option for vision correction.
Drawbacks of Glasses
However, there are also several drawbacks to wearing glasses such as:
Limited for Some Activities
Glasses can be cumbersome and limiting for some activities, such as sports or swimming.
Distracting
Glasses can also be distracting and cause discomfort in certain situations, such as tight-fitting glasses or those that do not fit well.
Obstruction
Glasses can also cause obstructions to the wearer's face such as mask wearing.
Benefits of Contact Lenses
For those who prefer contact lenses, there are several benefits, including:
Freedom of Movement
Contact lenses provide more freedom of movement, making them more comfortable for extended wear and ideal for sports and other physical activities.
Unobstructed Views
Contact lenses offer an unobstructed view, not withstanding from wearing a mask.
Change Eye Color
Contact lenses can also be used to change the color of the eyes, making them an attractive option for those who want to alter their appearance.
Drawbacks of Contact Lenses
Despite the numerous benefits, contact lenses also have several drawbacks, including:
Irritation
Contact lenses can cause eye irritation, dryness, and redness, particularly if they are not cleaned and stored properly.
Expense
Contact lenses are more expensive than glasses, requiring regular purchases or replacements.
Complex Usage
Contact lenses also require more complex usage, including cleaning, storing, and disinfecting, which may not be ideal for everyone.
Final Verdict
In conclusion, whether you prefer glasses or contact lenses, it ultimately depends on personal preference and lifestyle requirements. Glasses remain a practical and affordable option for vision correction, while contact lenses offer more freedom and flexibility, although requiring more care and expense.
