Glossary - Optical Center 


Astigmatism: Astigmatism is a common eye refractive error, similar to farsightedness and nearsightedness, which can be easily corrected. It is not an eye health issue.

Blue Light: The blue light emitted from computer screens is obviously tiny when compared to that emitted from the sun, but what makes blue light harmful is our prolonged exposure to it from staring at LED screens.

Cataract: A cataract is defined as the clouding of the eye’s natural lens, which is located behind the iris and the pupil. Cataracts are a natural eye condition and are the most common cause of vision loss in people aged over 40.

Computer: These single lens options help to alleviate computer vision syndrome (CVS), which typically includes eye strain, dry eyes, blurred vision, eye fatigue and neck or back pain resulting from working in front of a computer for prolonged periods of time.

Double vision: Double vision (or Diplopia) is a serious medical condition with several possible causes. The most common form is binocular, meaning it affects both eyes, or rather, it affects their ability to collate a single image in your brain.

Gradient lenses: These are sunglasses lenses, as their name suggests. The tint in gradient lenses recedes from top to bottom. The tint is darkest at the top, gradually fading until there is no tint at the bottom.

High Index:  They offer a higher refractive index compared to CR39 and Mid-index lens options of around 1.61.

Mirror lenses: Reflective lenses reflect more light than your average tinted lens, so they are particularly useful in environments where there can be a lot of light bouncing into the eye from a number of surfaces, such as water or snow.

Nearsightedness: Myopia is a common eye refractive error which causes light to reflect unevenly on the retina when focusing on distant objects. People with myopia usually have no problems seeing nearby objects.

Non Prescription: Plano lenses do not contain a corrective prescription. They are used purely for fashion purposes. Plano lenses include the same benefits as our normal prescription lenses, including 100% UV protection.

Normal 1.50: Our brand of lenses with a lens thickness of 1.50.

Ocular hypertension: The term ‘hypertension’ refers to high blood pressure, and ocular hypertension is a condition where the pressure in your eyes exceeds a healthy range.

Plano lenses: Plano lenses are lenses that have no visual correcting power.

Plastic lenses: CR39 1.50 index lenses are an affordable choice for daily use and are 20% lighter than glass lenses. They are made using high-grade plastic and sourced from very reputable suppliers.

Photochromic lenses: Photochromic lenses react when in direct contact with UV light. They offer a great alternative to switching between glasses and prescription sunglasses. In bright sunlit conditions, the lenses will darken, and as conditions become darker, the lenses will once again become clear.

Polarized lenses: Polarized lenses eliminate glare, which is defined as light reflected off any surface. These special lenses make it easy to see in sunny conditions and protect eyes from harmful UV rays.

Polarization: Polarized lenses are used to reduce glare from reflective surfaces, such as the surface of the water or dashboard of a car, by filtering out reflected light.

Polycarbonate: Thanks to their durability to withstand fractures, polycarbonate lenses are most commonly used for both semi-rimless and rimless eyeglass frames.

Presbyopia: Presbyopia is defined as the gradual loss of your eye’s ability to focus on nearby objects. It is an age-related condition and symptoms usually begin at around age 40.

Progressive: Progressive lenses that are multifocal allow for more than two prescriptions for clear vision regardless of an objects distance.

Reading glasses:  If you need optical correction for looking at material close-up, such as reading, typing, and working at a desk, then you require reading glasses.

RX: Prescription lenses.

Silicone Hydrogel lenses: This amazing new technology allows up to seven times more oxygen to reach the cornea compared to traditional hydrogel lenses, meaning that for the first time extended wear contact lenses did not lead to an increased health risk.

Single Vision lenses: Single vision lenses are designed to correct the results of an error in your eye’s refractive power. This allows the focus to be distributed evenly with light rays hitting the retina at the correct points, ensuring that your vision is clear.

Spherical aberration lenses: simple lenses (like those found in magnifying glasses or reading glasses) are parts of a plane or sphere: as such, they do not focus light perfectly, and the degree of imperfection is known as a spherical aberration.

Thin 1.61: Our brand of lenses with a lens thickness 1.61.

Tinted: Tinted lenses are ideal for athletes, outdoor enthusiasts, and anyone who leads an active lifestyle.

Transition: Ideal for watersports, on the road, and outdoor activities. This technology is rapidly becoming the new standard in sunglasses.

Triple Coatings: Free essential coating, Scratch Resistant Coating, Free Anti-Glare Coating, Free UV Protection.

Trivex lenses: Trivex lenses are very similar to polycarbonate lenses in terms of their thin and lightweight material, durability index, and UV protection.

Ultra-Thin 1.74: Our brand of lenses with a lens thickness 1.74.

Very Thin 1.67: Our brand of lenses with a lens thickness 1.67.
