High myopia increases the risk of blinding eye conditions, so regular follow-up is essential. At Clarity Optical, we understand your concern with Myopia progression and we make it a priority for prevention and treatment. With the right treatment & plan we an help you slow down that progression.



How to prevent myopia?

Many recent studies state that giving children and yourself  more time for outdoor activities at least 1 hour a day can prevent myopia development, and can reduce the risk of myopia by 30%.


Ortho-K or overnight contact lenses are the most effective optical treatment for myopia control. Studies show continuous wearing of Ortho-K lenses can slow myopia progression by 40-60%.



MiyoSmart Lenses

MiyoSmart lenses are innovative spectacle lenses for myopia control developed by Hoya. With (D.I.M.S) technology work to curb myopia progression average by 60%*. It also decreased axial elongation on average by 60% compared with those wearing single vision lenses.


Atropine Eye Drops

Recent studies state that using low dose of atropine eye drops 0.01%. 0.02%, 0.05% which are topical pharmaceutical method of reducing the progression of myopia. But more research are needed for knowing about the side effects of long-term use of atropine.

MiSight Contact Lenses

MiSight 1 Day is the first soft daily disposable contact lens worn during the day only and is suitable for those who don’t feel comfortable wearing contact lenses to sleep. It is also effective in slowing myopia progression by 50-60% when compared to conventional single vision contact lenses.
