Medicated glasses and sunshades serve different purposes. Both can be made with prescription lenses; medicated glasses are primarily for vision correction, while sun shades are for eye protection. Medicated glasses correct refractive errors in vision, while sun shades protect eyes from the sun’s harmful UV rays and reduce glare.
What is Medicated Glasses?
Medicated or prescription or corrective glasses are lenses specifically designed to correct refractive errors in vision, such as nearsightedness, farsightedness, and astigmatism. The lenses of medicated glasses are customised to the individual’s specific needs and are prescribed by an eye doctor or optometrist. The prescription is based on the person’s visual acuity, determined by a comprehensive eye exam.
Medicated glasses can also correct other vision issues, such as presbyopia, an age-related condition affecting the ability to focus on close objects. In addition to improving vision, medicated glasses can protect the eyes from harmful UV radiation, reduce glare, and improve contrast.
What is Sun Shades?
Sun shades, or sunglasses or shades, are eyewear designed to protect the eyes from the sun’s harmful ultraviolet (UV) rays. They are typically made with lenses with a special coating or material that filters out UV radiation. In addition to protecting the eyes from UV rays, sun shades also reduce glare and improve visibility in bright sunlight, making them useful for activities like driving, outdoor sports, and spending time at the beach or in other bright environments.
Sun shades come in various styles, including aviator, wayfarer, round, and sport-specific designs. They can be made with different lens colours and tints to enhance or optimise vision for specific activities or environments. They can also be made with prescription lenses for those who need image correction.
Difference Between Medicated Glasses and Sun Shades
The main difference between medicated glasses and sunshades is their primary function. Medicated glasses, also known as a prescription or corrective glasses, are designed to correct refractive errors in vision, such as nearsightedness, farsightedness, and astigmatism. They are customised to the individual’s needs and prescribed by an eye doctor or optometrist. The lenses of medicated glasses are typically straightforward and do not have any special coatings or tints.
On the other hand, sun shades, also known as sunglasses or dyes, are designed to protect the eyes from the sun’s harmful ultraviolet (UV) rays. They are typically made with lenses with a special coating or material that filters out UV radiation. In addition to protecting the eyes from UV rays, sun shades reduce glare and improve visibility in bright sunlight. While medicated glasses and sun shades can be made with prescription lenses for those needing vision correction, their primary functions differ. Medicated glasses are designed to correct vision, while sun shades protect the eyes from the sun’s harmful rays and improve visibility in bright sunlight.
