As such, we explore some of the lens options and their functionalities in this article to aid in your decision making process.
1. Transition lens
Transition lenses are designed to be clear for indoor use but automatically darken when they come into contact with sunlight or UV light outdoors. This is caused by the activation of molecules in the lens when they are exposed to ultraviolet (UV) rays. As UV rays can penetrate through clouds, transition lenses also darken even on cloudy days.

Transition lenses are proven for provision of 100% UVA and UVB protection.
2. Anti fatigue lens
These lenses are especially suitable for those who constantly suffer from eye strain and fatigue. The upper portion of the lens offers an ideal distance vision correction, while the lower part eases eye strains caused by close screen proximity thanks to a subtle power change feature. Beyond alleviating discomfort in the eyes when using screens, Anti-fatigue lenses can also be worn for a number of intermediate visual tasks, thanks to its versatility.

- Minus power lens aka myopia correction lens:
In today’s digital age, children are looking at screens more often, which may increase their risk of myopia. Myopia correction lenses help to control myopia and prevent eye degrees of children from increasing. To slow down myopia progression, myopia correction lenses create a volume of signal in the child’s eye against eye elongation. Correction is made through a single vision zone that enables light to be focused onto the retina, which causes the eye to respond by slowing down its axial length elongation. This allows children to have a clear vision.
Advantages:
- Can be worn comfortably by children at a younger age
- Proven to slow down the progression of myopia by about 15-30%
4. Blue light glasses
Excessive blue light may result in damage to your eyes, causing fatigue and unfocused eyes. Sources of blue light include LED lights, sunlight, computer monitors, tablet screens, smartphone screens and more. Blue light glasses prevent glare by filtering out blue light to effectively block the transmission of wavelengths emitted from devices.
Advantages:
- Reduces eye strain
Blue light glasses can reduce eye strain by protecting the eyes from the transmission of wavelengths emitted from screen devices.
- Prevents eye diseases
Too much blue light exposure can cause eye diseases such as age-related macular degeneration, as revealed by some experts. Blue light glasses help to reduce the likelihood of deteriorating eyesight and other eye diseases.
